100th Anniversary of DEHN....from a workshop to an

industrial enterprise

In our great-grandparents’ timeelectricity was by no means amatter of course. In the early20th century sufficient illumina-tion used to be a luxury and aprivilege of the upper class.

Electricity was at best availablein large cities but rarely in ruralareas. The first long-distancetransmission of alternating cur-rent took place in 1891.At that time Oskar von Millersucceeded in transporting elec-trical energy for the first timeover a distance of 176 kilome-tres from Lauffen / Neckar toFrankfurt / Main via a high-

voltage power line (20 kV).This marked the breakthroughof the transmission of alternat-ing current and was a signifi-cant step forward. But it wasstill a long way to go beforethe total population was effi-ciently and reliably suppliedwith electricity. It was only inthe early 1920s that electricitywas made accessible to manysmall towns for the first time.

During this eventful time, HansDehn founded his electricalinstallation company in Nurem-berg on 21st January 1910.

Now, many years later, and yetwithin a comparatively shortperiod of time, which was char-acterised like no other by thechangeful history of Germanyand its people, success and set-

back, war, reconstruction andeconomic crisis, DEHN celebrat-ed its 100th anniversary on21st January 2010.

Starting as a small electricalinstallation company, DEHNbecame a globally operatingfamily-owned company.

The following pages showsome milestones in the com-pany’s history of 100 years.

On 21st January 1910 the electrician Hans Dehnlaid the foundation for today’s company whenregistering an electrical installation business inNuremberg.

Since electric current had to be transported to theconsumer, building installation and particularlythe construction of overhead lines were the mainfields of activity for DEHN electricians under themanagement of Hans Dehn.

1910

After the first successful business years, a sub-sidiary is opened in Neumarkt i.d.Opf. locatedabout 45 km southeast of Nuremberg toadvance electrification in Upper Palatinate.

1921

Apart from overhead lineconstruction and building

installation, the installation of lightning protec-tion systems on buildings is an integral part of our business activities. Hans Dehn also starts todevelop and manufacture lightning protection

and earthing components.

1923

The company grows year after year and HansDehn’s sons Walter and Willy become partners.From now on, the family-owned company oper-ates under the name of DEHN + SÖHNE. In1941 the youngest son Richard becomes apartner.

1933

Hans Dehn quite early deals with lightning pro-tection. His first patent in this field is grantedin 1918.

1918



The Second World War inevitably slows downbusiness development. The premises in Nurem-

berg and Neumarkt are considerably damagedduring the war. Highly motivated, the familystarts reconstruction.The starting point for post-war activities inNeumarkt was a warehouse built in the lastmonths of the war near Hans-Dehn-Straßewhere our head office is located today.

1939 – 1945

The decision to builda hot dip galvanisingplant in Neumarkt

paves the way forthe extension of thesubsidiary to a pro-duction site.

1948

In the post-war period, businessbegins to pick up again:DEHN + SÖHNE presents light-ning protection and earthingproducts at the Hanover tradefair for the first time. Theincreasing market demand

requires a further extension of the production facilities inNeumarkt.

1952

DEHN seizes the opportunity to market itsproducts abroad: Austria becomes the firstexporting country.

1953

Due to our technical expertknowledge and entrepreneurialvision, we are the world’s first

manufacturer to realise thatexternal lightning protectionhas to be combined with inter-nal lightning protection.The first generation of surgeprotective devices is launched.

1954

The third product field besideslightning and surge protection -safety equipment - is launched.

The ball pin patented for DEHN+ SÖHNE in 1953 significantlyinfluences the state of the art.



The pioneering innovation of the separableearth rod considerably complements the rangeof earthing components and is still in greatdemand today.DEHN + SÖHNE becomes well-known in thefield of earthing technology.

1958

The product range is continuously complement-ed, especially in the field of surge protection.New protective devices such as VA 280 andBLITZDUCTOR are presented on the market.

1970 – 1980

The first lightning current carrying surgearrester enters the market: VGA 280/4, alsoknown as DEHNventil. It globally becomes asynonym for a new generation of surgearresters. DEHN + SÖHNE captures a leadingposition in the sector of surge protection.

1984

Foundation of DESITEK A/S in Denmark. It isthe first of today’s 10 sales companies in for-eign countries.

1988

The success story of surge protection startswith VM 280, the world’s first arrester with amodular width of 17.5 mm.

1986

The KS connector is devel-oped to reliably connectcircular conductors to flatprofiles.

1956

The universal MV clamp from our lightningprotection portfolio is launched.

In Switzerland DEHN + SÖHNE participates in theELVATEC AG, which has been distributing DEHNproducts on the Swiss market for several years.

1990



Development and implementation of the masterplan DEHN 2000.A milestone in the company’s history:DEHN+SÖHNE prepares for the future.National and international success requires com-prehensive restructuring, reorganisation andreorientation.

1991

The new energy-coordinated Red/Line arrester family for low-voltage consumer‘sinstallations is launched.Surge protective devices such as DEHNport and DEHNguard start their story ofsuccess.Red/Line becomes the general term for all protective devices for use in powersupply systems.

1993

The new energy-coordinated Yellow/Linearrester family for the protection of data tech-nology and automation systems, including thekey product BLITZDUCTOR CT, is another mile-stone of our research and development.

1996

The positive development in Spain requires newdistribution channels. DEHN IBERICA S.A. is found-ed in co-operation with our long-standing partner.

1992

In this year DEHN + SÖHNE is ready to makethe leap to America. DEHN Inc. is founded.

DEHN POLSKA Sp. z o.o. is founded in Warsawto serve the Polish market more efficiently.

1999

Failures of technical systems and installations are very unpleasantfor the operators. These require faultless operation from theequipment both under “normal“ conditions and in case of thun-derstorms. Loss reports of insurance companies show clearly that

there is a backlog demand both in the private (Fig. 1) and com-mercial sector (Fig. 2). A comprehensive protection conceptwould help to achieve this aim.The Lightning Protection Zones Concept enables designers, con-structors and operators to plan, perform and control protectionmeasures.All relevant devices, installations and systems are thusreliably protected and furthermore with economically acceptableefforts.

Sources of interferenceSurges arising due to thunderstorms are caused by direct or closelightning strokes or distant lightning strokes (Fig. 3).Direct or close lightning strokes are strokes into the lightning pro-tection system of a structure, into its immediate surroundings orinto the conductive systems entering the structure (e.g. low-volta-ge power supply, telecommunications lines and control lines...).

Due to their amplitudes and energy loads, the arising impulse cur-rents and impulse voltages as well as the corresponding electro-magnetic field (LEMP) represent a special risk for the system tobe protected.

In case of a close or direct lightning strike, the surges (Fig. 3:

Case 1a) are caused by a voltage drop at the impulse earthingresistance and the resulting potential rise of the structure towardsthe distant surroundings. This is the maximum load on electricalinstallations in structures.

The characteristic parameters of flowing impulse currents (peakvalue, rate of current rise, load, specific energy) can be describedwith the impulse-current wave form 10/350 µs (Fig. 4) and aredefined in international, European and national standards as testcurrents for components and devices for protection against directlightning strokes.

In addition to the voltage drop at the impulse earthing resistance,surges arise in the electrical building installation and the systems

connected to it and equipment due to the induction effect of theelectromagnetic lightning field (Fig 3: Case 1b).The power of these induced surges and the resulting impulse cur-rents is considerably lower than the power of a direct lightningimpulse current and is therefore only described with the impulsecurrent wave 8/20 µs (Fig. 4). Components and equipment, whichdo not have to conduct currents from direct lightning strokes, aretherefore tested with impulse currents of 8/20 µs.

Protection philosophyDistant strokes are lightning strokes from a distance to the objectto be protected, lightning strokes into the medium voltage over-head line network or into its immediate surroundings or lightningdischarges from cloud to cloud (Fig. 3: Cases 2a, 2b and 2c).

In analogy to induced surges, the effects of distant lightning stro-kes on the electrical system of a structure are controlled by devi-ces and components, which are designed accordingly for impulsecurrent wave 8/20 µs.Surges due to switching operations (SEMP) are caused by e.g.

– switching off inductive loads(e.g. transformers, coils, motors),

– ignition and interruption of electric arcs(e.g. arc welding device),

– tripping of fuses.

The effects of switching operations in electrical installations of structures can also be simulated with impulse currents of waveform 8/20 µs for testing purposes.

Lightning/Surges



To ensure continuous availability of complex power sup-ply and IT systems even in case of a direct lightningeffect, further measures for surge protection of electricaland electronic installations are necessary based on abuilding lightning protection system. Taking all causes of surges into consideration is very important. For this pur-pose, the Lightning Protection Zones Concept of IEC62305-4 is applied (Fig. 5).A structure is subdivided in different risk zones. These

zones help to define the necessary devices and compo-nents for lightning and surge protection.Part of an EMC-conform lightning protection zones con-cept is an external lightning protection system (includingair-termination system, down-conductor system, earth-ing), equipotential bonding, spatial shielding and surgeprotection for the power supply systems and IT systems.The lightning protection zones have to be definedaccording to Table 1.

In correspondence with the requirements and loads on

surge protective devices with respect to their installationsites, these are classified as lightning current arresters,surge arresters and combined lightning current andsurge arresters.The highest requirements for the discharge capacity aremade on lightning current and combined lightning cur-rent and surge arresters used for the transition fromLightning Protection Zone 0A to 1 or 0A to 2.

These SPDs must be able to conduct partial lightningcurrents (wave form 10/350 µs) several times withoutdestruction in order to prevent the penetration of

destructive partial lightning currents into the electricalinstallation of a building.At the boundary from LPZ 0B to 1 or downstream of thelightning current arrester at the boundary from LPZ 1 to2 and higher, surge arresters are used for protectionagainst surges. Their function is to further reduce boththe residual loads of the upstream protection levels andlimit the induced or own surges.

The aforementioned lightning and surge protectivemeasures at the boundaries of the lightning protection

zones apply to both power supply systems and IT sys-tems to the same extent.All measures described in the EMC-conform LightningProtection Zones Concept help to achieve a permanentsystem availability of a modern infrastructure.

DEHN – Technical Definitions.

Surge Protective Devices (SPD)

Surge protective devices are items of equipmentwhose basic components are voltage-controlledresistors (varistors, suppressor diodes) and/orspark gaps (discharge paths). The function of surge protective devices is to protect other elec-trical equipment and installations against imper-missibly high surges and/or to establish theequipotential bonding.Surge protective devices are classified

a) according to their application in

– Surge protective devices for power sup-ply systems and equipmentfor nominal voltage ranges up to 1000 V

• according to EN 61643-1:2001 as SPD Types1/2/3

• according to IEC 61643-1:1998-02 as SPDsClass I / II / III

– Surge protective devices for IT systemsand equipmentfor protection of modern electronic systems intelecommunications and signal-processing net-works with nominal voltages up to 1000 V a.c.(root-mean-square value (rms)) and 1500 Vd.c. against indirect and direct effects of light-ning strokes and other transients.

• according to IEC 61643-21:2000 + Corrigen-dum:2001, EN 61643-21:2001 and DIN VDE0845 Part 3-1.

– Isolating spark gaps for earth-termina-tion systems or for equipotential bond-ing

b) according to their impulse current dis-charge capacity and their protective effectin

– Lightning current arresters /

Coordinated lightning current arrestersfor interference due to direct or close light-ning strokes for protection of installationsand equipment (for use at the boundaries of Lightning Protection Zones (LPZ) 0A and 1).

– Surge arrestersfor distant lightning strokes, switching over-voltages as well as electrostatic dischargesfor protection of installations, equipment andterminal devices (for use at the boundariesdownstream of LPZ 0B).

– Combined lightning current and surgearrestersfor interference due to direct or close light-ning strokes for protection of installations,equipment and terminal devices (for use atthe boundaries between LPZ 0A and 1 as wellas 0A and 2).

Technical data of surge protective devices

The technical data of surge protective devicescomprise information defining the applicationconditions upon

– application(e.g. installation, mains conditions,temperature)

– performance in case of interference(e.g. impulse current discharge capacity,follow current extinguishing capability,voltage protection level, response time)

– performance during operation(e.g. nominal current, attenuation,insulation resistance)

– performance in case of failure(e.g. backup fuse, disconnection device,fail-safe)

Categories according to IEC 61643-21: 2001(DIN VDE 0845 Part 3-1)

For testing the current carrying capability andvoltage limitation under influences of impulses,a variety of impulse voltages and impulse cur-rents is described in IEC 61643-21:2001 (DINVDE 0845 Part 3-1). They are sorted in Table 3

and provide preferred values. In table 2 of IEC61643-22 (DIN VDE 0845-3-2) the source of transients is assigned to the different impulsecategories according to the coupling mechanism.Category C2 includes inductive couplings(surges), category D1 galvanic couplings (light-ning currents). The relevant category is specifiedin the technical data.

Cut-off frequency fG

defines the frequency-dependent performanceof an SPD. Cut-off frequencies are frequencies

causing an insertion loss (aE) of 3 dB under cer-tain test conditions (see EN 61643-21:2001).If no other value is indi-cated, the frequencyvalue refers to a 50 Ωsystem.



DEHN + SÖHNE surge protective devicesexceed the values indicated in the categories.The explicit value for the impulse current carry-ing capability is therefore indicated by the

stated nominal discharge current (8/20 µs) andlightning impulse current (10/350 µs).

Combined impulse UOC

is generated by a hybrid generator (1.2/50 µs,8/20 µs) with a virtual impedance of 2 Ω.Theopen-circuit voltage of this generator is de-fined as UOC. UOC is especially indicated forSPDs Type 3.

Degree of protection

The degree of protection (IP) corresponds tothe subdivision into degrees of protection inaccordance with DIN EN 60529 (VDE 0470Part 1).

Disconnecting time ta

is the time passing until the automatic discon-nection from power supply of the electricalcircuit or equipment to be protected in case of a failure. The disconnecting time is an applica-tion-specific value resulting from the intensityof the fault current flowing and the character-

istics of the protective device.

Disconnection capacity / Follow currentextinguishing capability Ifi

The disconnection capacity is the uninterfered(prospective) rms value of the mains followcurrent, which can automatically be extin-guished by the surge protective device at pres-ence of UC. It can be proven in the scope of anoperating duty test according to EN 61643-11.

Frequency range

characterises the transmission band or let-through frequency of an SPD according tothe described attenuation characteristics.

Insertion loss

With an indicated frequency, the insertion lossof a surge protective device is defined by therelation of the voltage value at the installationsite before and after installing the SPD.If no other value is indicated, the value refersto a 50 Ω system.

Repeated discharges with values beyond thespecifications of the device may overload SPDsused in IT systems. In order to ensure a high

system availability, SPDs should therefore besubject to systematic tests. LifeCheck allowsfor quick and easy SPD testing (refer also topage 177).

Lightning impulse current Iimp

is a standardised impulse current curve, with awave form of 10/350 µs. Its parameters (peakvalue, charge, specific power) simulate theloads of natural lightning currents.Lightning current and combined lightningcurrent and surge arresters must be capable of discharging such lightning impulse currentsseveral times without consequential destruc-tion of the equipment.

Mains-side overcurrent protection /Backup fuse

is an overcurrent protective device (e.g. fuse orcircuit breaker), which is installed outside of the surge arrester on the supply side to inter-rupt the power-frequency follow currents, if the breaking capacity of the surge protectivedevice is exceeded.

Max. continuous operating voltage UC

is the root mean square (rms) value of themaximum voltage, which may be applied tothe correspondingly marked terminals of thesurge protective device during operation. It isthe maximum voltage on the SPD in thedefined non-conductive state, which ensuresthat this state is regained after response anddischarge.The value of UC shall be chosen in accordancewith the nominal voltage of the system to beprotected and the requirements of the installa-tion provisions (IEC 60364-5-534).

Max. discharge current Imax

is the maximum peak value of the impulse cur-rent (8/20 µs), which can be safely dischargedby the device.

Max. transmission capacity

defines the maximum RF capacity which canbe transmitted via a coaxial surge protectivedevice without interfering with the protectivecomponent.

Nominal discharge current In

is the peak value of an impulse current (waveform 8/20 µs), which the surge protectivedevice is rated for according to a certain testprogramme.



Nominal load current (nominal current) IL

is the highest permissible operating current,which may be permanently conducted via thecorrespondingly marked terminals.

Nominal voltage UN

corresponds to the nominal voltage of the sys-tem to be protected.The nominal voltage isoften indicated for surge protective devices usedin IT installations for type designation purposes.For a.c. voltages it is indicated as rms value.

N-PE surge arresters

are surge protective devices exclusively designedfor installation between the N and PE conductor.

Operating temperature range TU

indicates the range in which the devices can beused. For devices without self-heating, it is equalto the ambient temperature range. The tempera-ture rise of devices with self-heating must notexceed the maximum value indicated.

Protective circuit

Protective circuits are multi-stage, cascaded pro-tective devices. The individual protection stagescan consist of discharge paths, varistors, semi-conductor elements. The energy coordination of the individual protection stages is performedwith decoupling elements.

Protective conductor current IPE

is the current flowing through the PE connectionwhen the surge protective device is connected tothe maximum continuous operating voltage UC,corresponding to the installation instructionsand without load-side consumers.

Response time tA

Response times generally characterise theresponse performance of the individual protec-tion elements used in surge protective devices(refer also to page 371).Depending on the steepness du/dt of the im-pulse voltage or di/dt of the impulse current, theresponse times can change within certain limits.

Return loss

indicates for high-frequency applications, howmany rates of the “forward“ wave are reflectedat the protective device (“transition point“).It is a direct measure for rating the adjustment

of the protective device to the surge impedanceof the system.

Series impedance

is the impedance in the direction of the signalflow between input and output of the SPD.

Shield attenuation

Relation of the power fed into a coaxial cable tothe power radiated through the cable from thephase conductor.

Short-circuit withstand capability

is the value of the prospective power-frequencyshort-circuit current controlled by the surge pro-tective device if it is supplied with an upstreambackup fuse.

SPD class (Yellow/ Line)

All DEHN surge arresters for use in IT systemsare assigned a Yellow/Line SPD Class and aremarked correspondingly with a symbol in thetechnical data sheet and on the rating plate

(refer also to page 151).

Thermal disconnector

Surge protective devices for use in power supplysystems, which are supplied with voltage-con-trolled resistors (varistors), mostly have an inte-grated disconnection device, which isolates thesurge protective device from mains in case of overloads and indicates this operating state.The disconnector reacts to the “joule heat“generated by an overloaded varistor and discon-nects the surge protective device from mains, if a certain temperature is exceeded.The disconnection device is designed to discon-nect the overloaded surge protective device intime to avoid a fire hazard. It is not designed toensure the protective measure of “protectionagainst indirect contact“.The function of these thermal disconnectors canbe tested by simulated overloads/ageing of theSPD.

Voltage protection level Up

The voltage protection level of a surge protectivedevice is the maximum instantaneous value of

the voltage on the terminals of a surge protec-tive device, determined from the standardisedindividual tests for

– Lightning impulse sparkover voltage1.2/50 µs (100%)

– Response voltage for a steepness of 1 kV/µs

– Residual voltage for nominal dischargecurrent Ures

The voltage protection level characterises thecapability of a surge protective device to limitsurges to a residual level. If used in power sup-ply systems, the voltage protection level defines

the location of use by the overvoltage categoryaccording to DIN VDE 0110-1:2003-11 (DIN EN60664-1, IEC 60664-1). For surge protectivedevices designed for protection of IT systems,the voltage protection level has to be adaptedto the immunity of the equipment to be protect-ed (IEC 61000-4-5: 2001-12).

Equipotential bonding

For lightning and surge protection reasons, it is strongly recommended toconnect the PV frame as follows to the equipotential bonding system:

• Defined connection with at least 16 mm2 copper at the PV frame (b).

• Defined connection with at least 6 mm2 copper at the PV frame(a + c).

• Electrically conductive connection of the PV frames has to be ensured.

• The earth conductor is connected to the main earthing busbar of thebuilding on ground level.

• The earth conductor has to be installed in parallel and in close proxi-mity to the d.c. and a.c. cables / lines and accessory.

DEHNventil® modular

Multipole modular combined lightning current andsurge arresterSPD Type 1 according to EN 61643-11

SPD Class I according to IEC 61643-1

• Prewired spark-gap-based combined lightningcurrent and surge arrester, consisting of a basepart and plug-in protection modules

• Maximum system availability due to RADAXFlow follow current limitation

• No tripping of 20 A gL/gG fuses up to short-cir-cuit currents of 50 kArms

• Discharge capacity up to 100 kA (10/350 µs)

• Protection of terminal devices

• Operating state/fault indication by indicatorflag in the inspection window

• Easy replacement of protection modules with-out tools due to module locking system withmodule release button

• Vibration- and shock-tested according to EN60068-2

For protecting low-voltage consumer´s installations against surges andeven direct lightning strikes. For installation in conformity with the light-ning protection zones concept at the boundaries from 0A – 2.

With their functional Red/Line design, the devices of the modularDEHNventil family combine safety and innovation. Designed for ”all-in-one installation”, the SPDs integrate lightning equipotential bonding andprotection against surges in a single device.This function is particularly of advantage in compact electrical installations. The design of the SPDsaccording to energy coordination criteria even allows protection of termi-

nal devices if they are close to the consumers ( 5 m). With their light-ning current discharge capacity up to 100 000 A, the SPDs ensure highavailability of the electrical installation to be protected. Even for expand-ed electrical installations, the modular DEHNventil devices offer variousapplication possibilities. Red/Line surge arresters installed at the bound-aries of the individual lightning protection zones are already energy-coor-dinated with DEHNventil devices. By using encapsulated creepage dis-charge spark gaps, combined with a compact design, DEHNventil unitsare well suited for use in switchgear installations or distribution boards.A special feature of the new modular DEHNventil family is its functionaldesign.The module release button is a key element. It ensures reliable fix-ation of the protection module to keep the safe connection to the basepart even in case of maximum loads. If protection modules have to bereplaced, the module is released without tools and can be removed easi-ly.The devices incorporate double terminals which are suitable for all con-ductors, allowing series connection in a space- and cost-effective wayaccording to IEC 60364-5-53 requirements for nominal currents up to125 A. For connecting further DIN rail mounted devices, busbars of type

MVS 3 8 6 and MVS 4 11 8 can beused. The right DEHNventil devicescan be easily chosen according tothe system configuration of thelow-voltage consumer´s installa-tion and type designation of the

device.

The patented RADAX Flow technol-ogy ensures follow current limita-tion and extinction as well as max-imum system availability of electri-cal installations to be protected. Even in case of short-circuit currents ashigh as 50 kArms, mains follow currents are reduced in such a way thatthere is a selectivity to lower fuse values, i.e. upstream fuses will not tripdue to arising mains follow currents.

The operating state/fault indication of each protective circuit immediate-ly provides information on the operating state of the surge arrester evenif no operating current is present. Apart from the standard green and redindicator, DEHNventil M ... FM devices feature a three-pole terminal forremote signalling.With their floating changeover contact, the remote sig-nal can be used as a break or make contact according to the particular cir-cuit concept.

• Protection of terminal equipment

• Maximum system availability

For protecting low-voltage consumer´s installa-tions against surges and even direct lightningstrikes. For installation in conformity with thelightning protection zones concept at theboundaries from 0A – 2.

The DEHNventil ZP combined lightning currentand surge arrester is specifically designed forconnection to busbar panels of supply meters. Itcan be snapped directly onto the busbar systemwithout the need for tools. Its reduced sizeleaves enough space for connecting cables fromthe service entrance box (SEB), even if threeselective main circuit breakers are installed.The operating state of the SPD is indicated by alight indicator which is controlled by a button.

Both with this kind of operating state controland due to its design as a spark-gap-based SPD,the DEHNventil ZP device has no leakage andoperating currents.The RADAX Flow spark gap technology allowsthe required selectivity for follow currents evenfor small-sized fuses in the service entrancebox. Unwanted interruptions of the power sup-ply due to tripping of main fuses are thus avoid-ed.The dimensioning of the parameters as well asthe complete concept of the device are fullycompliant with all requirements of the new

German VDN* Directive on the use of surge protective devices in primary power systems.

DEHNlimit PV 1000

Type 1 combined lightning current andsurge arrester for use in photovoltaic systems SPD Type 1 classification according to EN 61643-11

SPD Class I classification according to IEC 61643-1

• Prewired combined lightning current and surgearrester for use in photovoltaic generator cir-cuits

• For use in photovoltaic installations up to1000 V UCPV

• High lightning current discharge capacity dueto approved spark gap technology

• Maximum system availability due to spark gaptechnology with d.c. current extinction

DEHNlimit PV 1000: Combined lightning current and surge arrester for use in photovoltaic power supply systems up to1000 V d.c.

For protecting photovoltaic inverters against surges and even direct light-ning strikes. For use in accordance with IEC 60364-7-712:2002-05(Installation of photovoltaic power supply systems).

The combined lightning current and surge arrester of type DEHNlimit PV1000 was specifically developed for use in photovoltaic power supply sys-tems. The approved encapsulated creepage discharge spark gap technol-ogy allows reliable protection of photovoltaic generators and inverterseven in the event of direct lightning impulse currents. It is the voltage pro-tection level of DEHNlimit PV 1000 and reduction of the impulse time dueto the spark gap technology that allow for coordination of the SPD withthe equipment to be protected.

The d.c. extinction by the spark gap is a unique feature of DEHNlimit PV1000. Potential short-circuit currents up to 100 A caused by a trippingspark gap are interrupted within only a fraction of a second in case of aphotovoltaic voltage up to 1000 V d.c.

The combination of lightning current carrying capability, protection capa-bility and follow current extinction provides maximum availability of thePV system protected by DEHNlimit PV 1000.

DEHNbloc® M

Single-pole modular coordinatedlightning current arresterSPD Type 1 according to EN 61643-11


• Coordinated spark-gap-based lightning currentarrester consisting of a base part and plug-inprotection module




• Directly coordinated with DEHNguard surgeprotective devices without additional cablelength

• Low voltage protection level• Operating state/fault indication by indicator

flag in the inspection window


DEHNbloc M 1 ...: Single-pole modular coordinated lightning current arrester with high follow current limitation

DEHNbloc M 1 ... FM: With remote signalling contact for the monitoring system (floating changeover contact)


The modular devices of the DEHNbloc M product family are coordinatedlightning current arresters with a functional design.

Energy coordination with Type 2 surge arresters of the DEHNguard fami-ly is ensured without additional cable lengths or decoupling coils. This isone of the most important characteristics of the Red/Line product family.

The DEHNbloc M devices stand for performance and user friendliness in aconcise form.Their electrical parameters were rated for maximum require-ments for lightning and surge protection systems. DEHNbloc M is the ideal

device for use in main distribution boards of low-voltage consumer´sinstallations of a building. Equipped with the latest RADAX Flow sparkgap technology, the most important goal of DEHNbloc M is to ensure pro-tection and availability of electrical installations.

Due to the unique follow current limitation and follow current extinction,a follow current breaking selectivity is ensured even for small-sized fusesin installations. DEHNbloc M is leakage-current-free and has a mechani-cal operating state indication, allowing the device to be installed evenupstream of meter panels in low-voltage consumer´s installations.

When installing this modular arrester, the user of DEHNbloc M has allsafety characteristics and features this design has to offer. The vibration-

proof module locking system, for example, is unique. Shock or vibration

during transport or operation orenormous mechanical impulseloads resulting from discharges donot affect the module locking sys-tem which ensures safe fixationboth for the base part and protec-tion module. Nevertheless, the pro-tection modules can be easilyreplaced without tools by simplypressing the user-friendly module

release button. In order to avoidincorrect insertion by the installeror user when replacing the modules, both the base part and protectionmodule are mechanically coded. DEHNbloc M devices incorporate doubleterminals which are suitable for all conductors, allowing series connectionof the SPDs in a space- and cost-saving way according to IEC 60364-5-53requirements for nominal currents up to 125 A.

The operating state/fault indication of DEHNbloc M immediately providesinformation on the availability of the device even if no operating currentis present. Apart from the standard red and green indicator, DEHNbloc M... FM devices have an additional remote signalling output. With theirfloating changeover contact, the remote signal can be used as a break or

make contact according to the particular circuit concept.

DEHNbloc Maxi 1 255 S: Coordinated lightning current arrester with integrated backup fuse for busbars

For protecting low voltage consumer´s installations against surges. Forinstallation in conformity with the lightning protection zones concept atthe boundaries from 0A – 1.

DEHNbloc Maxi S allows to better integrate surge protective devices intoapplication environments of a low-voltage switchgear installation or dis-

tribution board.Due to its unique mechanical design, the coordinated DEHNbloc Maxi Slightning current arrester can be mounted directly onto the PEN/N busbarof a switchgear installation without requiring additional adapters.With the backup fuse integrated into the device, no further separate back-up fuses need to be installed.Installing the DEHNbloc Maxi S devices directly into the terminal panel of the switchgear installation upstream of the circuit breaker ensures shortcable lengths of the SPDs and a low voltage protection level for the instal-lation.With a discharge capacity of 25 kA (10/350 µs) DEHNbloc Maxi S fulfilsthe most stringent requirements of national and international lightningprotection standards for all three-phase current applications in TN and TTsystems.For “3+1“ circuits, DEHNgap Maxi S provides a powerful creepage dis-charge spark gap with a discharge capacity of 100 kA (10/350 µs).

DEHNbloc Maxi S also features the patented RADAX Flow follow currentlimitation thus allowing selectivity, even for small-sized fuses.

The capability of conducting lightning impulse currents without damageand suppressing mains follow currents without tripping upstream over-current protective devices ensures the availability of the switchgearinstallation in case of a lightning strike and considerably reduces the riskof arc formation in the installation.Combined with the DEHNsignal remote signalling system, the availabilityof DEHNbloc Maxi S devices can be monitored at any time.An optical fibre transmission to the DEHNsignal E 3 receiver module,which is easy to perform, ensuressafe electrical isolation betweenthe power circuit and the remotesignalling circuit.

The receiver module for opti-

cal fibre transmission of typeDEHNsignal E 3 transmitsremote signals of DEHNblocMaxi S and DEHNgap Maxi Ssurge protective devices.

The receiver module for opti-cal fibre transmission of typeDEHNsignal E 3 is particular-ly adapted to the place of installation of the coordinat-ed DEHNbloc Maxi S andDEHNgap Maxi S surge pro-tective devices.

The receiver module for opti-cal fibre transmission is ableto telemonitor three DEHN-bloc Maxi S SPDs and, if required, the N-PE protectivecircuit via optical fibre cables.

Considering the special installation environment of the surge protective

devices in a switchgear installation, communication via optical fibre cablebetween the protective devices and the DEHNsignal E 3 receiver moduleis a considerable benefit in terms of safety.The readiness for operation of the individual SPDs is transmitted to theDEHNsignal E 3 receiver module in the form of a visual signal via EMC-safe plastic optical fibre cables. The visual signals are evaluated in theDEHNsignal E 3 receiver module and are converted into an electrical sig-nal. The signal of the operating states can be directly read out at theDEHNsignal E 3 receiver module or is provided via a floating changeovercontact. The DEHNsignal E 3 receiver module features a green indicatorlamp to check its operating state. In addition to the function indication,the three indicator lamps of the selective operating state indication showthat the assigned protective devices are ready for operation. The receivermodule indicates if a protective device of a phase fails. The surge protec-

tive devices and the DEHNsignal E 3 receiver module are easily connect-ed via optical fibre cable by using the accessory parts described.

The spark gaps of the DEHNbloc lightning current arresters allow for acompact structure of low-voltage distribution boards. Using pressurisedencapsulated creepage discharge spark gaps, safety distances from elec-trical busbars and special flameproof enclosures are not required.

With a lightning current discharge capacity up to 50 kA (10/350 µs) perpole, DEHNbloc devices fulfil the most stringent requirements of nationaland international lightning protection and application standards.

The consistent development of the integration concept has made theDEHNbloc devices even more powerful: With the product designationDEHNbloc ... H, the groundbreaking RADAX Flow spark gap technology

for follow current extinction and follow current limitation was integratedinto the DEHNbloc family.

The RADAX Flow technology prevents operational interruptions caused bytripping conductor protection due to responding SPDs. In times where allsystems increasingly depend on a functioning electrical infrastructure, thisis an indispensable product feature. Due to the patented RADAX Flowprinciple, even the amplitudes of short circuits in installations up to 50kArms can be limited to approx.500 A and extinguished after approx.5 ms.This performance allows a breaking selectivity of the SPD even in case of small-sized fuses.

But the concept of the DEHNbloc H family also stands out due to otherproduct features:With its phase-side and earth-side double terminals, thesingle-pole device of type DEHNbloc 1 255 H offers a wide range of appli-cation possibilities.

DEHNbloc incorporates double terminals which are suitable for all con-ductors, allowing a series connection of three-pole DEHNbloc 3 255 HSPDs in a space- and cost-saving way according to IEC 60364-5-53requirements for nominal currents up to 125 A.

For application with other DIN rail mounted devices, multifunctional ter-minals are ideally suited for providing connection for conductors and bus-

bars.

DEHNbloc NH00 255 H wasespecially developed for usein industrial distributionboards and in power supplysystems. It can be installedinto size 00 NH fuse holdersor NH disconnectors accor-ding to the particular sys-tem.

DEHNbloc 1 440 is suitable

for rated voltages of 440 V.

For protecting low voltage consumer’s installations against surges andeven direct lightning strikes. For installation in conformity with the light-ning protection zones concept at the boundaries from 0A – 1 with 3+1 cir-cuits.

Being total current arresters between neutral and protective conductorsin TT systems, the single-pole N-PE lightning current arresters DEHNgapM, DEHNgap Maxi, DEHNgap Maxi S, DEHNgap BN and DEHNgap B NHare designed to meet the requirements for the protection of persons andmaterial assets in ”3+1 circuits”.The creepage discharge spark gaps werespecifically developed to meet this challenge. With a discharge capacityup to 100 kA (10/350 µs) they fulfil the highest requirements specified innational and international lightning protection standards. The leakage-current-free spark gap design allows the devices to be used upstream of

the meter according to national regulations (e.g. German VDN Directive).Being coordinated N-PE lightning current arresters, DEHNgap M,DEHNgap Maxi and DEHNgap Maxi S are different from other total cur-rent arresters. Due to their response performance, they can be coordinat-ed directly with N-PE surge arresters of the DEHNguard M family andDEHNgap S surge arresters without additional decoupling coil. If lightningcurrent and surge arresters have to be installed together at one site, noadditional DEHNgap S is required thanks to the low voltage protectionlevels of DEHNgap M and DEHNgap Maxi.The design and installation of DEHNgap Maxi S are adapted to the spe-cial characteristics of low voltage switchgear installations and entirelycomplement the application of DEHNbloc Maxi S.DEHNgap B NH was specifically developed for industrial plants as well asfor supply systems.This SPD can be easily integrated into existing size 00

NH fuse holders. The multifunctional terminals of the DIN rail mounteddevices DEHNgap M, DEHNgap Maxi and DEHNgap BN are suitable for

connecting conductorsand busbars, allowingwiring with other DINrail mounted terminals.The functional Red/Linedesign of DEHNgap Moffers many features forsafe and easy handling.The mechanical operat-

ing state and fault indi-cation, for example,stands for fulfilling the high safety requirements, just like the module lock-ing device which is unique for use with surge arresters. It fixes the protec-tion modules and the base part of the device firmly in place. Neither vibra-tion nor shock during transport nor the enormous electromagnetic forcesof lightning discharge can loosen the protection modules. Nevertheless,they can be easily replaced without tools by pressing the user-friendlymodule release button of the protection module. Each protection moduleis mechanically coded to avoid incorrect insertion by the installer or user.Apart from the standard visual indication of DEHNgap M, DEHNgap M ...FM features a three-pole remote signalling terminal. With its floatingchangeover contact, the remote signal can be used as a break or makecontact according to the particular circuit concept.

DEHNguard M ... CI 275 FM: with remote signalling contact for the monitoring device (floating changeover contact)

For protecting low-voltage consumer’s installations against surges. Foruse in conformity with the lightning protection zones concept at theboundaries from 0B – 1 and higher.

The modular surge arresters of the DEHNguard M ... CI family with theirfunctional Red/Line design combine short-circuit protection and surgeprotection in a single protection module.This sets new standards for user-friendly surge and short-circuit protection.The protective circuit with the arrester backup fuse integrated in the pro-tection module and the heavy-duty zinc oxide varistor in combinationwith the dual Thermo Dynamic Control monitoring device offer the advan-tage of easy installation and minimum space requirements.Due to the integrated arrester backup fuse the user does not have to

worry about arrester-specific dimensioning requirements such as backupprotection in case of short-circuits and impulse current carrying capacity.

The user has the possibility to implement space-saving surge protectionmeasures in installations up to short-circuit currents of 25 kArms whichcover all functions specified in the IEC 60364-5-53 installation standard.All circuits including the N-PE circuit feature an operating state indicationrequired in accordance with the IEC 60364-5-53 standard.The ”Thermo Dynamic Control“ monitoring device does not only evaluatethe surface temperature of the heavy-duty varistor but also the intensityof the discharge current. The mechanical visual indication with green andred flags, which is free of operating currents, shows if every protective cir-cuit is ready for operation. The visual indication indicates the activation of

the ”Thermo Dynamic Control“ monitoring device and the integratedarrester backup fuse.

Apart from the mechanical operating state/fault indication, the ...FM ver-sion of the DEHNguard M ...CI devices features a three-pole remote sig-nalling terminal. With its floating changeover contact, the remote signalcan be used as break or make contact according to the particular circuitconcept.

All benefits of the modular design of the DEHNguard M family were com-pletely integrated into the new DEHNguard M ... CI family.The system-configuration-specific product designation as well as the

”Thermo Dynamic Control“ monitoring device reflect the high safetyrequirements.The unique module locking system prevents the protection modules frombecoming loose due to shock during transport or due to the enormousforces of discharge. Nevertheless, the protection modules can be easilyreplaced without tools, the need to de-energise and removing the coverof the distribution board by simply pressing the user-friendly modulerelease button of the protection modules.To prevent incorrect insertion bythe installer or user, every protective circuit of the multipole and single-pole SPDs and every protection module is mechanically coded.

The surge arresters of the mutlipole modular DEHNguard M ... CI familyfeature multifunctional terminals on a standardised spacing of 1 module

for connecting conductors and busbars, allowing easy wiring with otherDIN rail mounted devices.Thus,a variety of applications can be easily con-nected in series in accordance with IEC 60364-5-53 for optimal protec-tion.

Multipole, modular surge arresterSPD Type 2 according to EN 61643-11SPD Class II according to IEC 61643-1

• Prewired complete unit consisting of a basepart and plug-in protection modules


• High discharge capacity due to heavy-duty zincoxide varistors/spark gaps


• Easy replacement of protection modules due tomodule locking system with module releasebutton

DEHNguard M WE ...: Modular surge arrester especially for use in wind turbines

DEHNguard M ... FM: With remote signalling contact for the monitoring device (floating changeover contact)

For protecting low-voltage consumer´s installations against surges. Forinstallation in conformity with the lightning protection zones concept atthe boundaries from 0B – 1 and higher.

The modular DEHNguard M ... surge arresters with their functionalRed/Line family design set new standards in terms of safety and user-friendliness. The approved protective circuit with heavy-duty zinc oxidevaristors in combination with the dual Thermo Dynamic Control monitor-ing device characterise the DEHNguard technology.

Many features of the device show that both safe surge protection and

reliability of the devices are the key element of the new modularDEHNguard. The application-oriented product designation, which makesthe choice of the adequate devices considerably easier, as well as themodule locking device, which is unique for use with surge protectivedevices, stand for fulfilling stringent safety requirements. It fixes the pro-tection modules and the base part of the device firmly in place. Neithervibration during transport nor the enormous electromagnetic forces of discharge can loosen the protection modules. Nevertheless, they can beeasily replaced without tools by simply pressing the user-friendly modulerelease button of the protection modules. In order to avoid incorrect inser-tion by the installer or user when replacing the modules, each protectivecircuit of the multipole surge arresters and each protection module aremechanically coded.

The dual Thermo Dynamic Control monitoring device was not only devel-oped on the basis of national and international product standards, but italso stands for experience of decades in the international use of surgeprotective devices and considers many fields of application where SPDsmight be damaged. Like with all DEHN surge arresters with ThermoDynamic Control, evaluation is based on the intensity of the dischargecurrent and the surface temperature of the heavy-duty varistor.The green

and red indicator shows if each protective circuit is ready for operation.Apart from this standard visual indication, DEHNguard M ... FM devicesfeature a three-pole terminal for remote signalling.

With their floating changeover contact, the remote signal can be used asa make or break contract according to the particular circuit concept. Thesurge arresters of the multipole modular DEHNguard M family featuremultifunctional terminals on a standardised spacing of 1 module for theconnection of conductorsand busbars, allowingeasy wiring with otherDIN rail mounted devices.Thus a variety of applica-tions can be connected inseries according to IEC60364-5-53 for optimalprotection.

DEHNguard® S / DEHNguard® S FM

Single-pole, pluggable surge arresterSPD Type 2 according to EN 61643-11SPD Class II according to IEC 61643-1

• Multi-purpose surge arrester consisting of abase element and plug-in protection module

• High discharge capacity due to heavy-duty zincoxide varistor



• Narrow (modular) design acc. to DIN 43880

• Multifunctional terminals for connecting con-ductors and busbars

• Easy replacement of protection modules due tomodule locking system with module releasebutton


DEHNguard S ...: Pluggable surge arrester consisting of a base part and plug-in protection module

DEHNguard S ... FM: With remote signalling contact for the monitoring device (floating changeover contact)


The universal features are characteristic of the single-pole devices of theDEHNguard S product family. Be it as a single device or in combinationwith other devices – DEHNguard S surge arresters always provide theright protective circuit. The modern Red/Line family design and its univer-sal features ensure safety and user-friendliness. The module release but-ton and the approved Thermo Dynamic Control SPD monitoring devicewith dual tripping performance characterise the devices of theDEHNguard S series.

Experience of decades in the international use of surge arresters has fur-

ther improved the latest DEHNguard generation compared to the previoustypes.

The module locking system, which is unique for use with surge protectivedevices, fixes the protection module and the base part firmly in place.Neither vibration during transport nor the enormous electromagneticforces of discharge can loosen this connection. Nevertheless, the modulescan be easily replaced without tools by simply pressing the user-friendlymodule release button of the protection modules.

In order to avoid incorrect insertion by the installer or user when replac-ing the protection modules, every base part and protection module ismechanically coded by the manufacturer.

Like with all DEHNguard surge arresters, the users of DEHNguard S canrely on the dual Thermo Dynamic Control SPD monitoring device. Thisensures maximum reliability of the devices, even under unfavourableenvironmental conditions. The green and red indicator shows if DEHNguard S is ready for operation.Apart from the standard visual indi-cator, DEHNguard S ... FM features a three-pole terminal for remote sig-nalling. With its floating changeover contact, the remote signal can beused as a break or make contact according to the particular circuit con-cept. The multifunctional terminals of DEHNguard S surge arresters aresuitable for connecting conductors and busbars, allowing an easy connec-

tion to other DIN rail mounted devices. Series connection according to IEC60364-5-53 for optimal protection is therefore possible for a wide rangeof applications.

DEHNgap C S

N-PE surge arresterSPD Type 2 according to EN 61643-11SPD Class II according to IEC 61643-1

• Specifically designed for use in ”3+1” and”1+1” circuits of TT systems acc. to IEC 60364-5-53 between neutral conductor N and protec-tive earth conductor PE

• High discharge capacity

• Two-part unit consisting of a base part andspark-gap-based plug-in protection module



• With remote signalling contact for SPD moni-toring device

• Easy replacement of protection modules with-out tools due to module release button


DEHNgap C S: N-PE surge arrester consisting of a base part and plug-in protection module

DEHNgap C S FM: With remote signalling contact for monitoring device (floating changeover contact)


The N-PE surge arrester DEHNgap C S ideally complements the single-poleDEHNguard S surge protective devices. Being a total current arresterbetween neutral conductor and protective conductor in TT systems, itsfunction is to ensure that the requirements for protection of persons andmaterial assets in so-called ”3+1” and ”1+1” circuits are fulfilled.

With the modern Red/Line design, DEHNgap C S provides safety and per-formance just like the DEHNguard S devices.The module locking system,which is unique for use with surge protective devices, combines the spark-gap-based module and base part to a powerful unit. Neither vibration

during transport nor the enormous electromagnetic forces of dischargecan loosen the protection module. Nevertheless, the protection modulescan be easily replaced without tools by simply pressing the modulerelease button of the protection module. The mechanical coding at theprotection module and base part prevents incorrect insertion by theinstaller or user.

Monitoring of the arrester temperature and an integrated disconnector,which is connected in series to the surge arrester, further increase thesafety of DEHNgap C S.

The green and red indicator shows if DEHNgap C S is ready for operation.

Apart from the standard visual indicator, DEHNgap C S ... FM incorporatesa three-pole terminal for remote signalling. With its floating changeovercontact, the remote signal can be used as a break or make contact accord-ing to the particular circuit concept. The N-PE surge arrester DEHNgap C

S features multifunctional terminals for connection of conductors andbusbars, allowing easy wiring with other DIN rail mounted devices. Seriesconnection according to IEC 60364-5-53 for optimal protection is there-fore possible for a wide range of applications.

• Prewired complete unit for standard systemconfigurations consisting of a base part andplug-in protection modules

• Clear operating state indication due to 3-stagevisual service life indicator <GREEN-YELLOW-RED> with linked remote signalling function

• ”Pro-Active Thermo Control” SPD monitoringdevice

• Recommends the user to replace the protectionmodule <YELLOW> before the SPD is threat-ened by overloads


DEHNguard TNC H LI: Multipole surge arrester with service life indicator for use in TN-C systems

DEHNguard TNS H LI: Multipole surge arrester with service life indicator for use in TN-S systems

DEHNguard TT H LI: Multipole surge arrester with service life indicator for use in TT and TN-S systems (”3+1” circuit)

DEHNguard T H LI: Single-pole surge arrester with service life indicator


The single-pole and multipole surge arresters of the DEHNguard ... H LIfamily provide maximum safety and user-friendliness and set new stan-dards in surge protection.With the Pro-Active Thermo Control concept, they are the first ”intelli-gent” surge arresters to warn the user of failures of the surge protectionsystem in due time. With this technique, this new SPD monitoring devicemeets the steadily increasing requirements on the availability of electricalsystems in industrial, commercial and domestic environments. The 3-stagevisual indicator along with a floating changeover contact for remote sig-

nalling always informs the user on the operating state of the SPD. If thereis a risk that the varistor might be irreversibly damaged due to anincreased energy load, the user is informed by the yellow indicator andthe remote signalling function that the surge protection module should bereplaced – before the installation is unprotected!Like the well-known multipole DEHNguard family, the application-basedtype designation makes the choice of products of the prewired completeunits considerably easier. Less installation errors and saving of installationwork at the same time are unbeatable advantages for the customer. Both

the triple monitoring device of each circuit with Pro-Active ThermoControl and the coding of the pluggable protection modules characterisethe maximum degree of safety of the devices. Damage caused by incor-rect subsequent insertion by the installer or the user is very unlikely.With DEHNguard T H LI, the user is also provided with a single-pole devicefor universal use.All types of DEHNguard ... H LI feature a three-pole terminal for remotesignalling. With their floating changeover contact, the remote signal canbe used as a make or break con-

tact according to the particularcircuit concept.All surge arrestersof the DEHNguard ... H LI familyincorporate multifunctional ter-minals for the connection of con-ductors and busbars, allowingeasy wiring with other DIN railmounted devices.

DEHNguard® M YPV SCI ... (FM)

Multipole arrester for use in photovoltaic systemswith three-step d.c. switching device SPD Type 2 classification according to EN 61643-11

SPD Class II classification according to IEC 61643-1

• Prewired modular complete unit for use in pho-tovoltaic systems consisting of a base part andplug-in protection modules

• Combined disconnection and short-circuitingdevice with safe electrical isolation in the pro-tection module prevents fire damage due tod.c. arcs

• Approved fault-resistant Y circuit preventsdamage to the surge protective devices in caseof insulation faults in the generator circuit

• Safe replacement of protection modules with-out arc formation due to integrated d.c. fuse

• Suitable for all PV systems in accordance withIEC 60364-7-712

DEHNguard M YPV SCI 600: Multipole, modular surge arrester with three-step d.c. switching device; for use in photo-voltaic systems up to 600 V

DEHNguard M YPV SCI 1000: For photovoltaic systems up to 1000 V

DEHNguard M YPV SCI 1200: For photovoltaic systems up to 1200 V

DEHNguard M YPV SCI ... FM: With remote signalling contact for a monitoring device (floating changeover contact)

For protecting low-voltage consumer’s installations against surges. Foruse in accordance with IEC 60364-7-712:2002-05 (installation of photo-voltaic power supply systems)

The modular surge arresters of type DEHNguard M YPV SCI ... (FM) werespecifically designed for protecting equipment in photovoltaic systems.The innovative three-step d.c. switching device makes these arrestersespecially safe so that they fulfil the requirements for modern photovolta-ic systems.The application features of the modular Red/Line family design are simi-larly unique as the three-step d.c. switching device. The module lockingsystem firmly fixes the protection modules in the base part of the arrester.Neither shock nor vibration nor the enormous forces of discharge affectthe safe connection to the protection module. Nevertheless, the protec-tion modules can be easily replaced without tools by simply pressing theuser-friendly module release button of the protection modules. Every pro-

tective circuit of the DEHNguard M YPV SCI ... (FM) and every protectionmodule is mechanically coded to avoid incorrect insertion by the installeror user.To fulfil the specific requirements for photovoltaic systems, the approvedsafety philosophies of the fault-resistant Y circuit consisting of three pro-tective circuits of the varistor and the combined disconnection and short-circuiting device were integrated in a single device.This synergy reduces the probability of an arrester failure in case of oper-ating and fault states which have to be considered in photovoltaic sys-tems.This ensures that the arrester is protected in case of overload with-out presenting a fire risk to the system. Even in case of voltages up to1200 V d.c. an arc, which is likely to occur in the surge protective deviceif a conventional disconnection device is activated, is extinguished imme-

diately and without risk. Fire protection is the top priority of theDEHNguard M YPV SCI ... (FM) arrester. A fuse particularly developed for

photovoltaic systems was integrated into the short-circuit path to ensuresafe electrical isolation in case of a faulty surge protection module, allow-ing de-energised replacement of the protection module without arc for-mation in case of a faulty surge protection module. This unique designcombines surge protection, fire protection and the protection of persons.DEHNguard M YPV SCI ... (FM) can be used in all low-, medium- and high-performance photovoltaic systems without backup fuse due to this inno-vative and unique design.

The green and red indicator flags show if every protective circuit is readyfor operation. Apart from this standard visual indication, DEHNguard MYPV SCI ... (FM) arresters also feature a three-pole terminal for remote

signalling. With their floating changeover contact, the remote signal canbe used as make or break contact according to the particular circuit con-cept. Like all surge arresters of the modular DEHNguard M family,DEHNguard M YPV SCI ... (FM) arresters incorporate multifunctional ter-minals on a standardised spacing of 1 module for connecting conductorsand busbars, allowing easy wiring with other DIN rail mounted devices.

V NH / VA NH

NH Surge arrestersSPD Type 2 according to EN 61643-11SPD Class II according to IEC 61643-1

• Surge arrester for use in size 00 and 1 NH fuseholders

• Zinc oxide varistor with monitoring device, dis-connector and integrated backup fuse (VA NHwith additional spark gap connected in series)

• Energy coordination within the Red/Line prod-uct family

• Fault indication by tripping indicator

V(A) NH00 280: Surge arrester for use in size 00 NH fuse holders

V(A) NH1 280: Surge arrester for use in size 1 NH fuse holders

V(A) NH00 280 FM: With fault indicator for remote signalling; allows for use of NH fuse holders with microswitch (tripping

distance of fault indicator max. 7 mm)

For protecting low voltage consumer´s installations against surges. Forinstallation in conformity with the lightning protection zones concept atthe boundaries from 0B – 1 and higher. German patented design.

The single-pole V NH and VA NH surge arresters show that surge protec-tive devices do not necessarily have to be designed exclusively for DINrails or socket outlets. Being adapted to the conditions in industrial sub-circuit distribution boards, V NH and VA NH devices are designed in theform of an NH fuse holder.This allows for easy integration into busbar sys-tems, as often applied in zones belonging to the operators of power sup-ply systems or in industrial installations. Thus, the advantages of busbarsystems such as easy installation, less installation time and reducedwiring also apply to surge protection. The idea of such a busbar system isconsistently continued with SPDs in NH design. V NH and VA NH surge

arresters can be installed and removed by means of a fuse switch discon-nector and a fuse handle.This makes it considerably easier to measure theisolation of the installation as the SPD does not have to be disconnectedany more.

Another considerable advan-tage of the V NH / VA NH fam-ily is the already integratedbackup fuse. If SPDs areinstalled in an earth fault- andshort-circuit-proof way, thisconsiderably saves space andcosts in distribution boards. In

case of type VA NH,a spark gap was connected in series to the heavy-dutyzinc oxide varistor with thermal monitoring and disconnection device of the V NH devices. VA NH devices provide reliable protection especially forlarge-scale systems with permanent isolation control. Apart from thestandard visual indication by a fault indicator, V(A) NH ... FM devices pro-vide a microswitch integrated into the NH fuse holder for remote sig-nalling.

DEHNrail M 2P ...: Two-pole surge arrester consisting of a base element and plug-in protection module

DEHNrail M 2P ... FM: With remote signalling contact for the monitoring device (floating changeover contact)

For protection of the power supply circuit of industrial electronics equip-ment against transient surges in switchboards. For installation accordingto the lightning protection zones concept at the boundaries from 1 – 2and higher.

The modular devices of the DEHNrail M product family stand out due totheir high performance parameters and new straightforward Red/Linedesign. The devices combine safety and user-friendliness in a single mod-ule.The low voltage protection level and comprehensive common and dif-ferential mode protection are ideally suited for the protection of terminaldevices in industrial electronic environments. The design of the deviceswith input and output terminals for series connection and the protectivecircuit designed for high load currents underline this concept.

Compact in design, DEHNrail M surge arresters feature a distinctive Y pro-

tection circuit and a combined SPD monitoring device and disconnectionmechanism.

The base part and protection module are coded thus preventing incorrectinsertion by the installer or user.

The new module locking system of the DEHNrail M product family isunique for surge protective devices. It fixes the surge protection moduleand the base part of the SPD firmly in place. Neither vibration duringtransport nor the electromagnetic forces of discharge can loosen the con-nection.

If the protective circuit is overloaded despite of the powerful characteris-tics of the devices, the module release button allows quick replacementof the protection modules without tools.

In addition to the standard greenand red indication, DEHNrail M ...FM devices feature a three-poleterminal for remote signalling.Withtheir floating changeover contact,the remote signal can be used as abreak or make contact according tothe particular circuit concept.

• Four-pole surge arrester consisting of a baseelement and plug-in protection module

• High discharge capacity due to heavy-duty zincoxide varistor/spark gap combination



• Easy replacement of protection modules with-out the use of tools due to module locking sys-tem with module release button

EN 60068-2

DEHNrail M 4P ...: Four-pole surge arrester consisting of a base element and plug-in protection module

DEHNrail M 4P ... FM: With remote signalling contact for the monitoring device (floating changeover contact)

For protecting the power supply circuit of industrial electronics equipmentagainst transient surges in switchgear cabinets. For installation in con-formity with the lightning protection zones concept at the boundariesfrom 1 – 2 and higher.

The four-pole, modular DEHNrail M 4P ... (FM) surge arrester was specifi-cally developed for protecting three-phase industrial electronics terminalequipment. Adapted to this kind of environment, the SPD with the newRed/Line design is suitable for 35 mm DIN rails. The low voltage protec-tion level and the comprehensive common and differential mode protec-tion are characteristic of DEHNrail M 4P ... (FM). In order to provide opti-mal low voltage protection levels for the terminal equipment to be pro-tected, the device features input and output terminals for series connec-tion. DEHNrail M 4P ... (FM) devices ideally adapt to the cable runupstream of the terminal equipment therefore not requiring additionalterminal blocks for outgoing cables.The very compact design of DEHNrailM 4P ... (FM) already incorporates the tried and tested disconnector. It dis-connects an overloaded SPD circuit from the mains without interruptingthe supply circuit.

The base part and protection module of the device are coded thus pre-venting incorrect insertion by the installer or user.

The new module locking system of the DEHNrail M family is unique forsurge protective devices. It fixes the surge protection modules and thebase part of the SPD firmly in place. Neither vibrations during transportnor the electrodynamic forces of discharge can loosen the connection.

If the protective circuits, which are rated for high load currents up to25 A, are overloaded despite of the powerful characteristics of the device,the protection modules can be easily replaced without tools by simplypressing the module release button.

Apart from the standard green and red visual indication, DEHNrail M 4P

... FM devices feature a three-pole remote signalling terminal. With theirfloating changeover contact, the remote signal can be used as a break ormake contact according to the particular circuit concept.

NF 10

The NF 10 mains filter is the ideal completion of surge protection for

industrial terminal equipment. Being a DIN rail mounted device, the mainsfilter is ideally suited for installation downstream of surge protectivedevices (e.g. DEHNrail M 2P 255). In addition to surge protection, thisensures protection against balanced and unbalanced high-frequency

interferences. The separate input and output terminals of the mains filter

ensure that an optimal protective effect of the device is provided for theequipment to be protected. This also allows to meet electromagnetic com-patibility requirements for constructing control systems and installationswhich do not relate to surge protection.

SPS Protector: Two-pole surge arrester with interference suppressor filter

SPS Protector

Two-pole surge arrester with filter

The SPS Protector combines surge protection and interference suppressorfilter in one compact device. This makes the device ideal for protectingsensitive terminal equipment in industrial automation systems (e.g. pro-grammable logic controls ”PLCs”). The coordinated surge protection andfilter functions complement one another and prevent core saturation of the filter in the event of high-energy transients. The separate input andoutput terminals ensure that an optimal protective effect is provided for

the device to be protected. The metal enclosure of the SPS Protectorensures that high-frequency interferences are discharged without interfer-ing with other devices close to the installation.The compact design of theSPS Protector already incorporates the approved disconnector. In case of overload, it disconnects the SPD from the mains without interrupting thesupply circuit. Apart from the green light, standard SPS Protector devicescan also be used for remote signalling.

DEHNsafe 230 LA: Surge protective device for use in cable ducts

DEHNsafe

Surge arrester for use in cable ducts

The DEHNsafe surge arrester particularly stands out due to its flexibleapplication options. DEHNsafe is a two-pole surge protective device for230 V terminal equipment which can be installed into cable ducts, butalso into flat flush-type boxes due to the minimal installation depth of only 31 mm. DEHNsafe incorporates a monitoring device and a thermaldisconnector. In addition to a visual operating state indication, the devicefeatures a programmable acoustic fault indication. With such an acousticsignal, the fault indication can be programmed for three different operat-ing states:

– Acoustic fault indication,

– Test function,

– Muting of the acoustic signal.

A triple TAE cover plate of any switch pro-gramme manufacturer can be used for coveringit. Thus, DEHNsafe adapts ideally to any socketoutlet design.The two available terminals for L, N and PE allowfor series connection to ensure that the surgeprotection is situated in parallel to the circuit tobe protected. If DEHNsafe surge arresters are

overloaded, the surge protective device does not necessarily interrupt thecircuit to be protected. DEHNsafe surge arresters feature a green and redLED for visual indication of the protective device.

Surge protective adapterType 3 according to EN 61643-11Class III according to EN 61643-1


• Visual operating state (green) and fault indica-tion (red)

• Mains filter (DEHNpro 230 F-Protector only)


DEHNpro 230: Protection for terminal devices

DEHNpro 230 F: Protection for terminal devices with mains filter

Adapters for protecting the power supply circuit of electronic devicesagainst transient overvoltages as well as high-frequency interferencevoltages (DEHNpro 230 F-Protector). For installation in conformity withthe lightning protection zones concept at the boundaries from 1 – 2 andhigher.

The surge protective adapters of the DEHNpro family provide surge pro-tection for electronic consumers connected to final circuits. In theDEHNpro 230 F-Protector, the powerful surge protective circuit of DEHNpro 230 Protector was supplemented by an interference suppressorfilter with a balancing and unbalancing effect. This combination of surgeprotection and filter prevents a core saturation of the filter in case of high-energy transients. The nominal current carrying capability of 16 A forDEHNpro 230 and 10 A for 230 F-Protector allows flexible use of these

devices in final circuits.The distinctive Y protection circuit ensures protec-tion even if the phase and neutral conductors in standard earthed socketoutlets cannot be identified. The integrated disconnector also contributesto the safety of devices and installations.The standard green and red LEDsinform the user on the operating state of the surge protective devices.The modern design of DEHNpro devices and the use of high-quality mate-rials ensure safety in a sophisticated appearance. The DEHNpro devicesthus ideally adapt to the environment. They create the right technicalambience already at the socket outlet for connecting the latest communi-cation and multimedia systems. The curved enclosure surfaces and thesmooth surface structure ensure that the DEHNpro devices will not losetheir original properties even after several years of application.

BLITZDUCTOR® XTUUniversal lightning current / surge arrester with actiVsense® technology

• Automatically detects the operating voltage• Optimally adjusts the voltage protection level to the voltage currently applied

Application:

• Suitable fo the vast majority of applications in information technology systems

• Ideally suited for telecommunications systems, bus systems and measuring and control equipment

The nominal current of the SPD is limited to 100 mA, allowing the device to be used for the vast majority of applicationsin information technology systems. In some applications where the signal line is also used for power supply the currentmay exceed 100 mA.

All signals are transmitted with signal frequencies up to 25 MHz.

In bus systems the SPD can be used for applications based on RS 485 / RS 422 interfaces (not RS 232).

For more detailed information, please refer to page 179.

SPDs for Information Technology Systems

General

The surge protection components of SPDs have no radioactive isotopesand usually consist of at least one voltage-limiting or voltage-switchingdevice, and sometimes of overcurrent-limiting components as well. SPDsconsisting of several stages, must be designed without blind spot, i.e. it hasto be ensured that the different protective stages are fully coordinatedwith each other. Otherwise, the protective stages will respond only partial-ly and lead to faults within the surge protective device.

Selection of SPDs

When selecting SPDs, the following aspects must be especially taken into

consideration:– Protective effect [Yellow/Line SPD class (discharge capacity and protec-

tion level)]

– System parameters (system voltage, nominal current and transmissionparameters)

– Installation environment (design, connection conditions and certifica-tions)

The selection guide according to interface/signal on pages 156 to 174 shallfacilitate the choice of the right SPD.

Relevant product standard for the SPDs:

IEC 61643-21 / EN 61643-21Low voltage surge protective devices – Part 21: Surge protective devicesconnected to telecommunications and signalling networks – Performancerequirements and testing methods.

Discharge capacity

According to IEC 61643-21 / EN 61643-21, SPDs must be tested with atleast one impulse voltage or impulse current as mentioned in thefollowing table, with the indicated number of impulses. Further tests canbe performed – even with different pulse amplitudes or quantities. Themaximum protection level during this or these tests is indicatedas voltage protection level UP measured at the output of the device.Category C represents especially disturbing pulses with a steep rate of rise

and less energy, compared to the disturbing pulses of category D, which issupposed to simulate high energy loads due to induced partial lightningcurrents.The category is also indicated in the technical data of the SPDs –both in the description of the discharge capacity (In, Iimp) and protectionlevel (UP).

Immunity of terminal devices to be protected

Within the scope of the test for electromagnetic compatibility (EMC), elec-trical and electronic equipment (devices) must have a predefined immuni-ty against conducted pulse interferences (surges).Requirements for the immunity and test set-up are specified in EN 61000-4-5.Different electromagnetic environmental conditions make different de-mands on the immunity of the devices. The immunity of a device is linkedto the test level applied. For classifying the different immunities of termi-nal devices, the test levels are subdivided into four different stages. Testlevel 1 includes the minimum requirements for the immunity of the termi-

nal device. Generally, the test level can be taken from the documentationon the device or requested from its manufacturer.

Test levels Corresponds to charging voltage

according to EN 61000-4-5 of the test generator

1 0.5 kV

2 1 kV

3 2 kV

4 4 kV

Protective effect of SPDs

Yellow/Line SPDs for use in IT systems can limit conducted interferences to

safe values to ensure that the immunity of the terminal device is notexceeded. For protecting a terminal device tested for test level 2, a surgearrester with a let-through value below the EMC test values of the termi-nal device has to be chosen:Impulse voltage < 1 kV in combination with a pulse current of someamperes (depending on the coupling network).

LifeCheck® SPD Test

Testing an SPD module via RFID technology (LifeCheck)

SPDdiagnostics with early

warning function!

Regular testing of SPDs installed

During operation, an SPD can be overloaded by discharge processesexceeding the equipment specification. In order to ensure high systemavailability, it is therefore essential to test SPDs on a regular basis.DIN EN 62305-3, supplement 3 (see table excerpt) specifies the maximumintervals between tests of external and internal lightning protection sys-tems.

Easy testing with LifeCheck

Maintenance of BLITZDUCTOR XT with integrated LifeCheck is particular-ly easy.LifeCheck uses modern RFID (Radio Frequency Identification) tech-nology for monitoring the protective circuit and for communication.Irrespective of downtimes of the system, LifeCheck allows for quick andeasy testing of SPDs by means of the hand-held DRC LC M3+ reader or astationary DRC MCM XT condition monitoring unit.

Signal before arrester failure

The 3-stage LifeCheck monitoring circuit with early warning functiondetects the extreme electrical or thermal load of all protection elements

of an SPD below their destruction limit. This can be read out within sec-onds and without contact by means a RFID reader. If the reader displays“OK“, no extreme load was detected. If the contrary is the case, the mod-ule has to be replaced as soon as possible in order not to threaten theavailability of the protected circuit.

Functional principal of the LifeCheck diagnostics systems

The diagnostics system consists of two functional units:

1. RFID reading and signalling device (reader)

Combined with a visual and electrical display, an electronic systemtransmits energy without contact to the RFID transponder in the SPD

via antenna. If the operating state can be read out, an “OK“ messageis displayed.

2. Monitoring unit within the SPD:

Diagnostics of the 3-stage LifeCheck monitoring circuit is combinedwith communication of the RFID transponder:

• Diagnostics of electrical overload (impulse current)

Lightning strikes or overvoltage exceeding the specified dischargecapacity of the SPD will damage or even destroy the protection ele-ments.This electrical overload is detected by the LifeCheck monitor-ing device. When reading out the transponder, the ”Replace SPD!”message appears.

• Diagnostics of thermal overload (overheating)

Active and passive protection elements which are operated in the

critical temperature range will be pre-damaged or even destroyeddepending on the type and duration. This overload is detected by theLifeCheck monitoring device.When reading out the transponder, the”Replace SPD!” message appears.

PLUGGABLE SPDs FOR DIN RAIL MOUNTING

BLITZDUCTOR® XTU

Universal lightning current /surge arrester

• With actiVsense technology

– Automatically detects the operating voltage of

the wanted signal from 0 to 180 V– Optimally adjusts the voltage protection level to

the operating voltage currently applied

– Low voltage protection level, also suited for the

protection of terminal equipment

• Eases your processes

– Reduction of the variety of types

– Only one type of SPD for different signal lines

– Easy planning and storage

– Can be easily retrofitted

Example of use of BLITZDUCTOR XTU.

BLITZDUCTOR XTU combined lightning current and surge arresters for theprotection of information and automation systems stand out due to theirnew, revolutionary technology: The nominal voltage is not specified thus

the arrester can be used for any voltage in the range from 0 to 180 V d.c.Its innovative technology allows the arrester to automatically detect thesignal voltage of the wanted signal and to adjust its protection perform-ance to this voltage. Moreover, it continuously adjusts its voltage protec-tion level to the operating voltage currently applied and is thus ideallysuited for all applications where changing voltages occur.

In case of interference, BLITZDUCTOR XTU arresters always have anadjusted, minimal residual voltage for every signal voltage thus providingmaximum protection for the devices and systems connected to them.

BLITZDUCTOR XTU arresters also considerably reduce planning effortsand minimise storage requirements. Even if it is not known at the plan-

ning stage which voltages are used for signal transmission, BLITZDUCTORXTU arresters now allow to specify a concrete protective device even atthe planning stage thus facilitating procurement and storage at the exe-cution stage of the project.BLITZDUCTOR XTU arresters are also ideally suited to be retrofitted intoexisting systems or to replace existing arresters as it is frequently notentirely clear which types of nominal voltage are to be used.This does notmatter if BLITZDUCTOR XTU arresters are used.

Completely mounted BLITZDUCTOR XTU.Two-part design with base part and SPDmodule. Particularly space-saving, for DIN

rail mounting.

c l i c k

The function-optimised design of the arrester allows both to safely plugthe arrester module into the base part and to remove it without problems.The module is secured in the base part by snapping it in (audible click).When pressing the grey buttons, the module can be removed with littleeffort. This is ensured by the laminated contacts in the base part and therelease spring of the module. A mechanical reverse voltage protectionensures that the module is installed in the correct position.

BLITZDUCTOR XTU arresters are pluggable, multipole and universal DINrail mounted lightning current and surge arresters for the protection of measuring and control circuits, bus systems and telecommunication sys-

tems in which high levels of availability are essential. For effective pro-tection of terminal equipment against lightning effects and surges, BLITZ-DUCTOR XTU arresters combine the permanently high impulse currentdischarge capacity of a lightning current arrester with the low voltageprotection level of a surge arrester which is optimally adjusted to theoperating voltage currently applied.

LifeCheck allows easy and fast testing of SPDs without removing themodule from the system circuit. Integrated into the SPD modules,LifeCheck permanently monitors the proper condition of the SPD and actslike an early warning system, detecting imminent electrical or thermaloverload of the protection components. The LifeCheck status can be readout within a matter of seconds via contactless RFID technology by means

of the portable DEHNrecord LC reader and shows the date of the last testof the SPD module.Stationary installed, a condition monitoring system allows condition-based maintenance of 10 BXT arresters (for more detailed information,please refer to page 359).

The module locking mechanism ensures safe operation, thus the arresterprovides protection against vibration effects and shock loads up to a 30-fold acceleration of gravity.The function-optimised design of the arresterensures both fast and easy replacement of the arrester module whichhouses all relevant protection elements.

A wide range of accessories makes the BLITZDUCTOR XTU arrester partic-ularly user-friendly. Elements for labelling, earthing of unused lines or

easy testing of lines complete the product range.

Example of use of BLITZDUCTOR XT with an earthing module (grey). Thelines can be measured by means of the measuring module (grey strings)without disconnecting the clamps.

BLITZDUCTOR XT combined arresters are pluggable, multipole, universalDIN rail mounted lightning current and surge arresters for the protectionof measuring and control circuits, bus systems and telecommunicationsystems. They are particularly suited for installations and systems in whichhigh levels of availability are essential. For effective protection of termi-nal equipment against the effects of lightning and overvoltages, BLITZ-DUCTOR XT arresters combine the permanently high impulse current dis-charge capacity of a lightning current arrester with the low protectionlevel of a surge arrester.LifeCheck allows quick and easy SPD testing without removing the mod-ule.

Information on SIL

The term safety integration level (SIL) is defined in the internationalIEC 61508 and IEC61511 standards and is used in the field of functionalsafety. It is intended for assessing the reliability and safety of electrical,

electronic or programmable electronic systems. "Functional safety"describes the safety level of a system or installation, which depends onthe correct operation of sub-systems and external installations to reduce

the risk. The aim of functional safety is to minimise the risk of failure of the individual sub-systems so that the risk for the entire system or instal-lation is reduced to an acceptable level.The values in the table below can

be used for calculating the functional safety of systems with the surgeprotective devices used.

DEHNconnect RK

Terminal block with integratedsurge protection

• Minimum installation width of only 6 mm

• Quick installation with jumper bar

(accessory part)• Spring-loaded connection system

6 mm two-pole terminal block with integrated surge protection and cageclamp terminal. Earthing via DIN rail or clamp.

DEHNconnect RK is a 6 mm terminal block with integrated surge protec-tion and has five spring-loaded cage clamp terminals allowing two linesto be protected and equipotential bonding to the terminal equipment tobe established.The snap-in fixing at the supporting foot allows the device

to be safely earthed via the DIN rail. For reduced wiring, jumper bars canbe plugged into the protected side of the SPD to transmit signals.As theenclosure of the SPDs is open on one side to minimise the width, a cov-ering plate should be used at the end of every SPD block.

DEHNconnect RK is available in two per-formance classes:DCO RK M:

Surge arrester with energy-coordinatedprotection stagesDCO RK E (D):

Surge arrester with diodes only, forimproving the electromagnetic compati-bility (EMC) of terminal equipment

DCO RK

A wide range of accessories such as jumper bars, marking plates or coveringplates make DCO RK a system easy tooperate, which has been specificallydesigned for use in industrial environ-ments.

DCO RK Accessories

IP 20

In order to minimise the width, the enclo-sure is open to one side. For protection

against electrical shock, the SPD can beclosed with a covering plate (accessories).If several devices are arranged next toeach other, one covering plate could besufficient.

BLITZDUCTOR® VT

Lightning current / Surge arrester

• Cost-effective protection of multi-core signallines

• Interface-specific types, e.g. TTY, RS 485• Types for d.c. power supply systems

Compact protection with screw terminals for multi-core lines for DIN railmounting.

BLITZDUCTOR VT is a family of compact DIN rail mounted SPDs and con-sists of different types of enclosures. Most of the SPDs protect 4-wire sig-

nal lines or special applications. The equipment is earthed via a screw ter-minal.

BVT enclosure family

The enclosure concept of BLITZDUCTOR VTis variable. Depending on the application,SPDs are distinguished between

– width: 1.5 modules,4 protected signal lines

– width: 1.5 modules,2 protected lines for d.c. power supplysystems

– width: 3 modules,6 protected lines for RS 485/422

Connection to the ground has to be performedwith a terminal instead of the snap-on DIN rail.Direct equipotential bonding can be establishedto the terminal device with the second terminalcompartment of this double terminal.

The resistors at the circuit output protect theoptocoupler and protective diodes in the terminal

equipment against overloads.

Dimension drawing BVT TTY

Owing to the additional decoupling resistors at the output, only diodes in the terminal equipment,which can withstand loads only to a certain extent, are integrated into the energy coordination of the protective stages. This is especially important for optocoupler interfaces.

COM PACT SPDs FOR DIN RAIL MOUNTING

BLITZDUCTOR ® VT KKS

Combined lightning current and

surge arrester for cathodic corrosion prot ect ion systems

• M aximum efficiency due to high dischargecapacity

• Easy maintenance due to remote signallingcontact

• Resistant to permanent interference voltagesup to 65 V a.c.

SPD for protecting active cathodic corrosion protection systems.

Integrated floating remote signalling contact (break contact) for function

monitoring.

The protective circuit and voltage measuring circuit are protected against

surge impulses caused by atmospheric discharges (lightnin g) or swi tching

operations (in power supply lines).

The devices are designed for operation at permanent interference volt-

ages up to 65 V a.c. betw een pipelines and earth. If thi s value is exceed-

ed, the relevant regulations for protection against electrical shock have to

be considered and further measures have to be taken.

The devices can be overloaded by overcurrents caused by mains faults

(short circuits or earth faults). Therefore, they should be installed into a

separate metallic enclosure or a prewired terminal unit (ITAK) should be

used.The integrated remote signalling contact ind icates thermal overload

of the discharge paths.

In cathodic corrosion protection systems,

SPDs for protective circuits and voltage

measuring circuits are often used at the

same t ime. For easy identi f icat ion, the

SPDs have different colours, i.e. yellow f or

voltage measuring circuits and red for

protective circuits.

BVT KKS surge arr ester fam ily

Experience has shown that the installa-

tion of SPDs into a separate metal enclo-

sure is reasonable as the enclosure pro-

vides additional protection from over-

loads caused by short circuit s. Wit h ITAK,

DEHN provides adequate prewired units

for cathod ic corrosion prot ection systems.

The ITAK serial number serves as refer-

ence number for ordering.

ITAK, Serial No. 4305

DEHN has long-

standing experience

in using SPDs for

p ipel ine networks

and wou ld bepleased to assist

you to f ind the

appropriate protec-

tion for your appli-

cations.

Lightning current arrester for 10 pairs.DRL plug (1 pair):Surge protective plug for 1 pair, energy-coordinated withDRL plug-in SPD blocks.

Lightning current arrester, surge arrester or combined lightning currentand surge arrester, pluggable into type 2 LSA disconnection blocks. The10-pair plug-in SPD block with lightning current carrying capacity incor-porates gas discharge tubes (optional visual fault indication) and discon-nection block contacts. This allows for testing, disconnecting or patching

of pairs with plugged-in protection or the additional attachment of single-pair surge arresters for optimal protection of terminal equipment. Thesurge arresters snap into the earthing frame and can be removed as ablock, whenever required.

The plug-in SPD block has disconnection contacts that are compatiblewith the disconnection block. A measuring or disconnection adapter canbe plugged into the DRL in the same way as a disconnection block toensure protection during maintenance operation.

With the appropriate earthing frame, the fine limiting DEHNrapid LSA sin-gle-pair surge arresters can be plugged directly into the DRL plug-in SPDblock or optionally into LSA disconnection blocks.The decoupling imped-

ances integrated in the protective plugs allow energy coordination withthe DRL plug-in SPD block irrespective of the cable length. The single-pairplug also allows partial insertion of disconnection blocks including thepossibility to plug protective plugs with different circuits or nominal volt-ages into one block.

The integrated unit of plug-in SPD block, earthing frame and protectiveplug (combined lightning current and surge arrester) can be completelyremoved and plugged in. The combined lightning current and surgearrester corresponds to SPD Class GO.

Pluggable surge arresters for use as protection blocks in IT installationsand devices, which have to be connected via terminal or disconnectionblocks with LSA IDC terminal. Installation onto terminal blocks, however,is the preferred method, as their contact forces provide better fixation –

even in case of slight vibrations.

The surge arresters for 10 pairs can be easily installed and removed fortesting purposes.The contact to earth via the mounting frame is automat-ically established when plugging in the SPD. After being overloaded, theprotection elements can be individually replaced.

DEHN Enclosure for Equipotential Bonding

Enclosure system for SPDs protecting IT equipment

• Premounted enclosure system for wiring andprotection components

• Tested lightning impulse current carryingcapacity

• Optimised for equipotential bonding (surgearrester and shield connection)

• Metal enclosure, lockable against unauthorisedaccess

DEHN enclosures for equipotential bonding (DPG) are lockable metalenclosures and intended for installation of wiring and protection compo-nents. Available in four different sizes, the enclosures which are capableof carrying lightning currents provide terminals to integrate surgearresters and shields into the equipotential bonding.

Enclosure with lightning current carrying capacity, IP 40, for differentdesigns of distribution boards and for the insertion of surge arresters. Thecover can be removed from the wall plate without tools and is equipped

with a lock with cylinder quarter turn and a key. The C-shaped design of the wall plate facilitates installation work by sidewise or front access. LSAmounting frames or DIN rails can be attached to the wall plate by meansof cable entry plates and cable rails.

Despite of a high packing density, a structured cabling management isensured – crossings between cabling and wiring are avoided and thecabling of e.g. the LSA blocks becomes concise due to the 30 mm grid. For

this kind of cabling, an optional shield connection system is available(constant force spring). The sophisticated earthing system permanentlyconnects all conductive components of the enclosure system by mechan-ical contacting or earth conductors by means of an earthing block.

DEHN enclosures for equipotential bonding (DPG) are available in 4 dif-ferent sizes, allowing for the insertion of 3/6/12/22 LSA blocks. Even if 20/50/100/200 pairs are used, enough space is provided for the earth con-ductor block for supporting shielded sheath wires.

DEHN enclosures for equipotential bonding (DPG) in 4 different sizes

The shields of incoming conduc-tors can be contacted with con-stant force springs of type SA KRFin a space-saving way and withlightning current capacity. All

equipotential bonding conductorsare led together in the centralearthing block.

DEHNpatch

Surge arrester

• Patch cable with built-in surge protection

• Cat. 6 according to ISO/IEC 11801

• For universal use up to 48 V

• Easy to retrofit

DEHNpatch is the first Cat. 6 certified patch cable with built-in surge pro-tection that can be used universally according to EN 50173 for voltagesup to 48 V d.c.

Designed as a patch cable, DEHNpatch is easy to install.The unit is equal-ly suited for use in new installations or retrofitting into existing installa-tions at any time with little effort.DEHNpatch is simply plugged in between the patch panel and the activecomponent (a switch for example) instead of the conventional patch

cable.The snap-in mechanism of the supporting foot allows the device tobe safely earthed via the DIN rail. For single applications, a section of DINrail and a fixing device are included as a standard while for multiple appli-cations in 19“ distribution boards an optional DEHNpatch mounting setis available as an accessory. DEHNpatch fulfils the requirements of

Category 6 and can be universally used for all data services up to nomi-nal voltages of 48 V. It is equally applicable to existing services in officesand industrial environments such as Gigabit Ethernet, ATM or ISDN aswell as future systems such as Voice over IP and Power over Ethernet.Thanks to its fully shielded design, DEHNpatch can be used in shielded

and unshielded networks. Its width is similar to that of an RJ45 socketthus allowing up to 24 devices to be installed in one series and integrat-ed into a 19” rack.DEHNpatch is supplied with a standard patch cable length of 3 m and 5 m(other lengths available on request).

DEHNgate

Lightning current and surge arrester

• Application-specific SPD designs

• SPD for use in satellite and cable TV systems

with measuring output• Combined lightning current and surge arrester

with a high discharge capacity and low protec-tion level

• Contact materials with extremely highendurance

Lightning current and surge arrester for use as cable adapter to protectcoaxial systems such as CCTV, mobile radio stations and antenna systemsfrom potential damage.

DEHNgate is a family of lightning current and surge arresters with a cableadapter design for protecting coaxial systems such as mobile radio sta-

tions and antenna systems from potential damage. Depending on theapplication, different mechanical and electrical types are available.

DGA FF TV can be mounted onto a DIN railin a space-saving way to protect satellitesystems with several outputs. For singleapplications such as cable TV, the devicecan be simply snapped into a wall-mount-ed adapter. 2 F cable connectors are alsoincluded.

Delivery of DGA FF TV

The coaxial DGA arrester family comes indifferent designs for different applica-tions. Different types of plugs and arrestertechnologies allow for optimised solu-tions. Further types are available onrequest.

DGA arrester family

If high partial lightning currents can becoupled into antenna lines or if very high

transmission performances are required,the use of Lambda/4 surge arresters isadvisable. If additional remote supply isneeded for the antenna, a combination of a gas discharge tube and Lambda/4 tech-nology (DGA LG) should be used. Thesurge arresters are made of top-qualitymaterial and provide excellent endurance.

Application of Lambda/4arresters

The Lambda/4 surge arresters of typeDGA L4 feature an internal coaxial con-nection of the inner conductor as a band-pass. Only frequencies within this bandare transmitted. For low-frequency

impulses, such as lightning currents, theycause a short circuit. This makes themmechanically very robust and mainte-nance-free. Due to their low protectionlevel and high discharge capacity, theycan be used as combined lightning cur-rent and surge arresters.

Principle of Lambda/4

Spark-gap-based surge arresters have an internal gas-filled surge arrester and can bedefined as a low pass.This also allows for d.c. transmission (antenna supply). Peak volt-ages exceeding the threshold value of the gas discharge tube are discharged.These surgearresters provide extensive contact surfaces from the inner conductor to the gas dis-charge tube. This minimises burn-off of the material during the discharge process andensures a constant transmission performance.

SPDs FOR TERMINAL CONNECTION

DSM

Surge arrester

• SPD for telecommunications equipment

• For space-saving flush mounting

• Easy installation due to plug-in terminals

Surge arrester for protection of telecommunications equipment for instal-lation into flush-type boxes or small-sized distribution boards. Plug-in ter-minals at the input.

In a typical installation, DSM surge arresters are integrated into the dis-tribution socket downstream of the socket outlet of the terminal equip-ment or into the cable duct. This makes them independent from the switchor box programme and protect, invisibly for the user, telecommunications

systems or devices. Of course, the SPDs can also be integrated into small-sized distribution boards. The use of the removable plug-in terminalsmakes the installation of DSM easier. As each plug-in terminal is designedfor four lines, through-wiring of an S0 bus, for example, is possible.

DSM is compact enough to allow forthe types to be installed easily eveninto small-sized distribution boards

situated in damp rooms.

SCREWABLE SPDs

DEHNpipe

Surge arrester

• Maximum protection due to installation intothe cable run

• Surges are discharged via the enclosure of thefield device

• For nearly all types of two-conductor fielddevices with suitable cable gland

Surge arrester for outdoor use to be screwed onto two-conductor fielddevices. Stainless steel, IP 67.

DEHNpipe is made of corrosion-resistant stainless steel and is screwedonto the field device instead of a conventional cable gland. The perma-nently installed lines are then connected to the terminals of the fielddevice. Thus the protective components are directly situated in the cablerun. This provides an energy-coordinated surge protection. The SPD pro-

tects the inside of the field device against dangerous overvoltage with theinterfering impulses being discharged via the metal enclosure only andnot via the inside of the field device. Earthing accessories are also avail-able for plastic field enclosures.

DEHNpipe is designed for two-conductormeasuring sensors with 4-20 mA inter-faces.The surge arresters provide energy-coordinated surge protection for space-limited field devices in outdoor areas andreduce installation work.

Due to the two-part design of the SPD, the field cable can be connectedas usual, just like being connected to a measuring sensor.

Thanks to the cable gland a degree of protection of IP 67 is achieved.DEHNpipe supports common earthing concepts for cable shield treatmentof field cables. Depending on the cable gland used, the cable shield isearthed directly or indirectly or is not earthed at all. Indirect earthing inte-grates the shield into the protective concept – without leakage pickups.

BLITZDUCTOR® XT Ex (i)

Surge arrester

• Effective protection with minimum spacerequirements

• For use with 2-pole, 3-pole or 4-pole intrinsical-ly safe interfaces

• Function-optimised design for safe handlingand easy installation

• Quick testing of LifeCheck-equipped SPD mod-ules

• ATEX approval, FISCO

Pluggable, multipole, universal surge arrester for use in intrinsically safesystems with integrated LifeCheck monitoring device.

BLITZDUCTOR XT EX is a pluggable, four-pole, universal DIN rail mountedsurge arrester designed for the most stringent requirements on the avail-ability of intrinsically safe measuring and control circuits and bus systems.With regard to intrinsic safety, the SPD is considered earth-free and itsself-inductance and self-capacitance are negligibly small. The high

impulse current discharge capacity (min. 10x) and the low voltage protec-tion level are supported by the low-impedance design of the device.LifeCheck allows for quick and easy testing of SPDs. However, the SPDmodules may only be read out by means of the hand-held DRC LC readerin non-explosive atmospheres.Integrated into the SPD modules, LifeCheck permanently monitors the

proper condition of the SPD. Like an early warning system, LifeCheck reli-ably detects potential electrical and thermal overloads of the protectioncomponents. The LifeCheck status can be read out within a matter of sec-onds by means of DEHNrecord LC via contactless RFID technology andalso shows the date of the last test of the SPD module. A stationary con-

dition monitoring system allows status-oriented maintenance of 10 BXT.To ensure safe operation, the SPD provides protection against vibrationeffects and shock up to a 30-fold acceleration of gravity. The function-optimised design of the devices allows both quick and easy replacementof SPD modules which house all relevant protection elements. The SPDmodule and the base part must be ordered separately.

Completely installed BLITZDUCTOR XT EX.Two-part design with universal base partand application-specific SPD module.Particularly space-saving, for DIN railmounting.

Shield connection system for anchor bars which is capable of carryinglightning currents. The yield of the cable materials used is compensatedby a slipping spring element.

Shield connection system, tested with lightning currents, for specific useon anchor bars. As, in the course of time, the conductor materials are subject to a yield, this yield is compensated by a slipping spring element. Theshield connection of the rail types can also be installed using adequate

insulating elements after isolating it from local potential.

This very robust shield connectionsystem is particularly suited forcables with medium-sized diame-ters. It has been tested with light-ning currents and was approvedfor nuclear installations.

Shield Connection on DIN Rails


• Corrosion-resistant stainless steel material• Permanent shield connection with spring ele-

ment

Shield connection system with lightning current carrying capability,partic-ularly suited for smaller cables, for DIN rails with slipping spring elementfor compensating the yield of the cable materials.

Shield connection system, tested with lightning currents, for versatileapplications in DIN rail installations. Suitable especially for smaller cablediameters such as bus cables. As, in the course of time, the conductor

materials are subject to a yield, this is compensated by a slipping springelement.The shield connection of the rail types can also be installed usingadequate insulating elements after isolating it from local potential.

Shield Connection for Cables


• Extremely space-saving• Permanent shield connection with spring ele-

ment

Extremely space-saving shield connection system for use as constantforce spring. A spring element compensates the yield of the cable materi-als used.

The shields of incoming IT and power supply lines can be contacted bymeans of constant force springs of type SA KRF in a space-saving way andwith lightning current carrying capability. As, in the course of time, the

conductor materials are subject to a yield, this can be compensated by aspring element. For permanent corrosion protection of the clamping point,it is wrapped with a self-bonding SKB rubber tape.

For use in explosion-hazard areas

Ex isolating spark gaps of the EXFS L / EXFS KU product family are usedwhen the direct interconnection of electrically conductive installationcomponents in Ex areas is not applicable. As, for example, in case of cathodically corrosion protected pipeline sections.ATEX-certified EXFS L and EXFS KU spark gaps provide approved and test-ed safety in accordance with harmonised European standards.The arc-resistant tungsten-copper electrodes ensure a long service life of the Ex spark gaps.The approved type EXFS L with flexible conductor connection quicklyadapts to any application environment. The prewired spark gaps provideconnecting cables with different lengths with cable lugs, screws and M10nut. The flat or angled connection brackets (IF), which are available as

accessories, allow for easy connection of the spark gap to pipelineflanges.The EXFS KU type is enclosed in a damp-proof PVC enclosure and is idealfor underground installation at insulating couplings.

Pipe Clamp for Explosion Hazard Areas

For fixing at pipes in explosion hazard areas

• For use in explosion hazard areas Ex zones 1and 2 (gases, vapours, fogs) as well as Ex zones21 and 22 (dusts)

• Tested for explosion group IIB

• Time-saving installation – deactivation of thesystem/areas for welding or drilling work notnecessary

Pipe clamp for explosion hazard areas from Ø26.9 mm(¬”) to Ø88.9 mm (3”); Ø88.9 mm (3”) to 300 mm andfrom Ø300 to 500 mm.

Separate clamping body for endless tightening strap (PartNo. 540 901) from Ø26.9 mm (¬”) to 500 mm.

Pipe clamp for electrical contacting of pipes in explosion hazard areas, for

implementing of lightning equipotential bonding according to EN 62305-3(VDE 0185-305-3)

So far, the method of choice for implementing equipotential bonding andlightning equipotential bonding terminals in explosion hazard areas hasbeen welding or threaded bushings. Using pipe clamps was only permit-ted if there was proof of ignition spark immunity in case of lightning cur-rent loading. DEHN + SÖHNE has now provided evidence of ignition sparkabsence for a pipe clamp at lightning current loading. By realising the testaccording to EN 50164-1 (VDE 0185-201): Requirements for connectioncomponents (clamps and connectors) in a potentially explosive atmos-phere, absence of ignition sparks was proved for the test sample with alightning current carrying capability up to 50 kA (10/350 µs). The designof this novel pipe clamp for explosion risk areas not only provides a safeelectrical contact by means of two contact clips, but also the mechanicalfixing by an electrically insulated clamping body.

The Ex pipe clamp can be connected by

– round conductor, Cu, St/tZn,Al, StSt with Ø8/10 mm or flexible / strand-ed copper conductors, cross section 16-35 mm2

, with E-Cu crimpedcable lug (DIN 46235)

– flat copper conductor with minimum dimension 20x2.5 mm and aØ10.5 mm bore hole

SDS

Voltage Limiting Device

• Electrical isolation of insulated track sectionsand earthed parts of installations

• Safe equipotential bonding in case of a shortcircuit or earth fault at the overhead contactline due to high-current-resistant welding ofthe electrodes

• Discharge of surges without formation of shortcircuits due to lightning-resistant SDS ... volt-age limiting device

• Short-circuit withstand capability 25 kArms /100 ms; 36 kArms / 75 ms

SDS ...: Cylindrical SDS spark gap unit for insertion into rail adapter Siemens No. 8WL6503-xx

DIN EN 50122-1 describes the use of voltage limiting devices for d.c. anda.c. railways for so-called ”open earthing of railways” for live compo-nents of overhead contact lines and current collectors.In order to prevent the occurrence of hazardous surges between the insu-

lated tracks or track sections of electrical railways and earthed parts of the installation, voltage limiting devices (SDS ...) are used.

Their function is to connect parts of the installation in overhead contactlines and current collectors permanently to the return circuit, as soon asthe threshold voltage is exceeded.

In case of atmospheric overvoltages, the lightning-resistant SDS ...voltagelimiting device is capable of returning to its initial state after dischargingthe impulse current. Only if the specified lightning current loads areexceeded, a permanent short circuit is initiated by heavy-current-resistantwelding of the electrodes and the fuse link has to be replaced.

The SDS voltage limiting device consists of a spark gap unit and therespective connecting kit for direct connection to the rail or overhead con-tact line tower.

The spark gap unit type SDS 1, Part No. 923 110, developed by DEHN +SÖHNE, has also been approved by the German Federal Railway Authority(EBA).

Condition Monitoring System LifeCheck®

• Maximum protection and availability of sys-tems by means of permanent condition moni-toring of LifeCheck-equipped SPDs

• The early detection system already detectsarrester overload and warns of imminent fail-ure of the arrester

– Visual indication of faulty or previously dam-aged SPDs

– Compact dimensions and minimum wiring

– Monitoring of up to 10 SPDs (40 signal lines)

– Remote signalling contact

– Remote signalling also via RS 485 interfaceand PC software

Example of use of the DEHNrecord condition monitoring system.

Condition Monitoring:

The DRC MCM XT condition monitoring system is a compact DIN railmounted device for monitoring the condition of up to 10 pre-programmedBXT arresters with integrated LifeCheck monitoring circuit.

ntegrated into the SPD modules, LifeCheck permanently monitors the

proper condition of the SPD and acts like an early warning system,detect-ing imminent electrical or thermal overload of the protection components.The LifeCheck status can be read out within a matter of seconds via con-tactless RFID technology by means of the portable DEHNrecord LC deviceand also shows the date of the last test of the SPD module. Stationaryinstalled, the condition monitoring system supports condition-basedmaintenance of 10 BXT.

The unit acts like an early warning system, generating a fault messageeven in case of imminent arrester overload, indicates it by means of theintegrated three-colour LED and transmits it to one of the two integratedremote signalling contacts. Failure of the monitoring unit, e.g. due to avoltage breakdown, is also indicated via the remote signalling contact.The Show function integrated into the DRC MCM system allows to detect

previously damaged SPDs in the monitoring group.

If several condition monitoring systems are used in one switchgear cabi-net, these systems are connected via the integrated RS 485 interfaces tosynchronise the monitoring cycles. Up to 15 DRC MCM systems can beconnected to the RS 485 bus. Thus, up to 150 BLITZDUCTORs or 300 pairscan be monitored simultaneously with minimum wiring effort.

The ”Status Display and Service Console” PC software

is an optional user software for the DRC MCM XT condition monitoringsystem which indicates the status of the SPDs and addresses LifeCheck-equipped BLITZDUCTOR modules.The software can be installed on a standard PC using an RS485/USB inter-face converter of type ”USB-NANO 485” which is available as accessory.

The software can be downloaded free of charge fromwww.dehn.de/download/ or is available as CD for a nominal fee.

Graphical status indication of DRC MCM XT monitoring devicesand of all programmed protection modules assigned to them.

The Service functions allow to switch to the ”Service Console”function complex. The protection modules can be easily addressed,

tested and reset due to the user-friendly user interface.

LifeCheck® SPD Test Device

• A higher degree of protection and availability isachieved by preventive maintenance.

– The LifeCheck monitoring device detectsthermal or electrical overload of all compo-nents.

– To avoid imminent failure and thus systemdowntime, the SPD module should bereplaced as soon as possible.

• This type of SPD testing has the following ben-efits:

– Very easy and within a matter of seconds

– Module does not have to be removed duringsystem operation

– Detection of thermal or electrical overload ofall components

Preventive maintenance:

When using this maintenance strategy, SPDs are tested and measured at

regular intervals. The SPDs are assessed according to certain criteria and,if required, replaced.

In the past, this was very time consuming, expensive and required down-time of the system.For some years, SPDs with LifeCheck feature have been available whichallow to determine the status of the SPD via RFID technology. A monitor-ing circuit with a transponder in the SPD permanently monitors the pro-tective circuit for impermissible overload due to thermal overheating orelectrical impulse currents.

Information is read out via a hand-held tester. This tester incorporates thereader, an RFID reader unit.It contactlessly transmits electromagnetic energy to the transponder in

the SPD, reads out the status and displays it. Information is simple: "SPDOK" or "Replace SPD!". This test is carried out easily within a matter of seconds and without removing the SPD.The test can be carried out at anytime without interruption as it does not interrupt signal transmission.

This type of monitoring reliably detects thermal and electrical overload of all components, generally before the SPD fails and the availability of thesystem to be protected is limited. In addition, no expertise is required fortesting. The reader also facilitates documentation of the test results,which is mandatory in compliance with the EN 62305-3 standard.The test data (date, time, results) of all SPDs are saved and can be trans-mitted to a PC for printing or storage via USB interface. Thus a higher

degree of protection and availability is achieved by means of preventivemaintenance with LifeCheck as it already detects overload of componentsbefore the protection of the system circuit fails.

III and IV 2 years 4 years 1 year

It makes no sense to inspect SPDs for information technology systemsvisually since the status of the devices is generally not visible. For this pur-pose, another method has to be selected as is the case for completeinspections. In the past, measurement equipment was used to test SPDs.These measurements were very time consuming, required expertise andthe measurements did not provide sufficient information.

General Terms of Sale

1. General,Scope

1.1 All deliveries and services in business dealings withentrepreneurs take place exclusively under our generalterms of sale (hereinafter “terms of sale”). We opposedeviating regulations,especially conflicting terms of pur-chase of the customer, unless we expressly agreed to thevalidity in writing. Our terms of sale apply even if wecomplete unconditional delivery to the customer whileknowing that the terms of sale of the customer are in

conflict with our own.1.2 Our terms of sale only apply to entrepreneurs within the

meaning of section 310, paragraph 1 of the German CivilCode (BGB), to current business relationships and to allfuture transactions with the customer.

2. Offer and Order, Reservation of Right of Modifi-

cation and Copyright

2.1 Insofar as not expressly indicated by us as binding, doc-uments such as diagrams, drawings, and measurementsare only roughly binding.

2.2 Should our order confirmation contain reasonable expan-sions, limitations, or other modifications with respect tothe order, then the customer’s agreement is implied, if itdoes not immediately, at the latest however within 3business days from receipt of the order confirmation,oppose it.

2.3 Any order placed in our web shop shall be regarded as anoffer to conclude a sales contract. A sales contract only

comes into existence if the customer receives a writtenorder confirmation or the goods are delivered / servicesare rendered.

2.4 Our goods are only delivered in the packaging units indi-cated in the catalogues. If a different number of items isordered, the amount and price of the next larger packag-ing unit is considered agreed upon.

2.5 We reserve the right to make technical modifications toour services, insofar as such modifications promote tech-nical progress or are unavoidable based on other circum-stances and are reasonable for the customer.

2.6 We reserve ownership and copyright rights to diagrams,drawings, calculations, and other documents; these maynot be made available to third parties without ourexpress written consent.

3. Prices, Value-Added Tax, Packaging Costs

3.1 Our prices are subject to change without notice.3.2 Prices include, insofar as nothing else is arranged, cus-

tomary packaging from our plant without value-addedtax. On the day of invoicing, the legally identified VATamount is to be reimbursed to us.

3.3 The cost of non-customary packaging, e.g., collective orseaworthy packaging, is invoiced separately. The custo-mer bears the cost of the disposal or return of packaging.

4. Passing of Risk, Optional Insurance

The risk of accidental loss, destruction, or deteriorationpasses to the customer upon dispatch to the customerfrom our plant, even if carriage-paid delivery is agreedupon. At the request and expense of the customer, wewill insure the delivery against breakage, damage togoods in transit and fire damage.

5. Payment Due Dates, Discounts, Right of Refusal,

Default, Small Order Quantity Surcharge

5.1 Unless otherwise agreed, invoices are payable net 10days. Purchaser shall pay the costs of payment. Discount

amounts are deductible only if they have been agreed onwith us and all accounts payable due have been paid.

5.2 If purchaser is in default with his payments, interest onthe outstanding amount shall be payable at the rate of 8 % above the base interest rate. We reserve the right toprove and allege higher default damages. We reserve theright to cause default by demanding early payment. If weare required to advance performance and, if after theexecution of the contract, it becomes apparent that ourclaim, in particular for payment, may be jeopardised bypurchaser’s inability to perform we may refuse perform-ance.

5.3 The customer cannot charge counter-claims against ourdue payment claims or exercise a right of retention,unless the customer is entitled to a claim recognised bydeclaratory judgement that is not contested by us and if,while exercising the right of retention, the counter-claimfrom the customer is based on the same contractual rela-tionship.

5.4 Orders, with the exception of cash sales, for which thenet amount (invoiced amount without shipping costs andvalue-added tax) is less than € 75.00, a small order sur-charge of € 25.00 will be charged.

6. Retention of Title, Assignment, Release of Securities

6.1 Delivered goods remain our property until the paymentof all open business claims up to the point of invoicing.The claims of the customer including value-added taxfrom the resale of reserved goods, i.e., from a work per-formance using our goods, should already be transferredto us in the amount of the open invoice. In the case thatthe reserved goods from the customer are sold togetherwith other goods that do not belong to us, whether it be

without or after processing, or are delivered within theframework of a working contract, the assignment of theresulting claim of the reserve buyer is calculated in theamount of the value of the reserved goods.

6.2 Should the value of the granted securities exceed theclaims by more than 10 %, we are obliged to retransferor release the securities upon request. We shall select thesecurities to be released.

6.3 Our goods may only be transferred within the frameworkof proper business activity. The customer is not allowedto pawn or transfer the ownership of goods that are stillin our possession.

6.4 At our request, the customer is obliged to inform us of the purchaser and the arranged price and to show theassignment to its debtor.

7. Delivery Period and Appointment

7.1 The start of the delivery period presupposes the involve-ment of the customer for the clarification of all technical

questions.7.2 Delivery periods as well as delivery schedules will be

appropriately extended if they cannot be adhered to as aresult of military mobilisation, war, uprising, strike orlockout, delayed delivery of raw and auxiliary materials,late delivery by our suppliers, or similar circumstancesbeyond our control.A lasting obstruction under these cir-cumstances gives us the right to withdraw from the con-tract without liability for damages.

8. Liability for Material and Title Defects

8.1 Insofar as there exists a defect of the contract subjectthat was beyond our control, we can choose to fix thedefect or provide a defect-free contract subject (replace-ment).

8.2 Should the replacement (No. 8.1) not function properly,or should it be unreasonable to the customer, or shouldwe seriously and conclusively refuse it or unreasonablydelay it, or if other circumstances exist that,upon weigh-

ing mutual interests, justify immediate resignation orcompensation, then the customer is entitled to choose tolower the contract price or to withdraw from the contractand/or demand compensation (No. 8.3). The customer isnot entitled to withdraw from the contract if onlyinsignificant contract inconformities exist, especiallyinsignificant defects.

8.3 Should the customer exclusively choose compensationafter proper replacement (No. 8.2), the contract subjectremains with the customer,if it considers this reasonable.Compensation is limited to the difference between thepurchase price (without value-added tax) and the valueof the defective subject of the contract that remains withthe customer.

8.4 Material and title defect claims, including claims for com-pensation due to material and title defects, with theexception of claims under the Product Liability Act, lapse12 months after delivery of the goods.

8.5 Numbers 8.1 through 8.4 do not impair the customer’s

rights if we maliciously concealed a defect or if weoffered a quality guarantee.

9. Liability for Other Reasons

9.1 Our liability is excluded for slightly negligent infringe-ment of immaterial contractual obligations. Our liabilityis limited to the contractual, foreseeable damage fornegligent infringement of other obligations.

9.2 The above regulation does not apply to claims under theProduct Liability Act. Insofar as the limitation on liabilitypursuant to No. 9.1 for claims from the producer’s liabil-ity pursuant to § 823 of the German Civil Code does notinterfere, our liability is limited to the replacement of theinsurance. Insofar as this does not occur or does notoccur in full, we are liable up to the insured amount.

9.3 Insofar as our liability is excluded or limited, this alsoapplies for the personal liability of all of our employees,representatives, and vicarious agents.

9.4 Our liability is unrestricted if the customer loses his/her

life or suffers a bodily or health injury due to an action orfailure attributable to us.

10. Return of Goods without Legal Liability

10.1 If no legal claim to return exists, delivered goods willbe accepted only with previous agreement from us.Returns without previous agreement will be send back– postage-due – to the sender without inspection. Thecustomer bears the shipping costs for the return deliveryin No. 10.1.

10.2 The goods must still be in their original packaging.Special orders or deliveries, which date back more than

three months or the net value of which is less than€ 75.00, cannot be returned.A processing fee of 15 % of the net value of the goods will be charged to cover thecost of the return. If the goods can no longer be resold atthe list price at the time of the return, an additionaldeduction (old goods deduction) will be made in additionto the processing fee. If we make an exception and agreeto accept the return of parts that are unpackaged or thatare no longer in their original packaging, an expenseremuneration of at least 15 % will be charged forreworking and repackaging in addition to the processingfee and, if applicable, the old goods deduction.

10.3 Returned goods will only be credited to a new invoice.Credits cannot be used to clear invoices due at the timeof the return.

11. Product Information, No Advisory Obligation

Our deliveries are intended only for speciality stores orskilled users. Our user information and instructions are

limited to the details of each written product information(e.g., installation instructions, catalogues, data sheets).Further advisory obligations do not exist. Application,use, and processing of the products lie solely in the cus-tomer’s realm of responsibility.

12. Use and Protection of Customer Data

We use customer data, which concern the business deal-ings with the customer, in terms of the Federal DataProtection Act.

13. Applicable Law, Jurisdiction

13.1 German law applies to the mutual contractual obliga-tions, their materialisation, interpretation, and imple-mentation as well as all resulting contractual and busi-ness relationships. The application of the UN Agreementon Contracts on the International Purchase of Goods andthe thereafter enacted laws of the Federal Republic of Germany is excluded.

13.2 Place of performance and jurisdiction for delivery, pay-ment, and for all obligations, including those from ex-change and cheque payments, is exclusively Nuremberg.We reserve the right to file a complaint against the cus-tomer at its official location.
