Masterpact Schneider Electric1

The original Masterpact has set a new standard for power circuit breakersaround the world. Over the years, other major manufacturers have tried tokeep up by developing products incorporating Masterpacts mostinnovative features, including the breaking principle, modular design andthe use of composite materials.

Today, Schneider Electric continues to innovate with the new Merlin GerinMasterpact NT and NW ranges.

In addition to the traditional features of power circuit breakers(withdrawability, discrimination and low maintenance), Masterpact nowoffers built-in communications and metering functions, all in optimisedframe sizes.

Masterpact NT and NW incorporate the latest technology to enhance bothperformance and safety. Easy to install, with user-friendly, intuitiveoperation and environment-friendly design, they are, quite simply, circuitbreakers of their time.

Five performance levels

N1 - for standard applications with low short-circuit levels.H1 - for industrial sites with high short-circuit levels or installations withtwo parallel-connected transformers.H2 - high-performance for heavy industry where very high short-circuitscan occur.H3 - for incoming devices supplying critical applications requiring bothhigh performance and a high level ofdiscrimination.L1 - for high current-limiting capability and adiscrimination level (37 kA) as yet unequalled byany other circuit breaker of its type; intended forthe protection of cable-type feeders or to raise theperformance level of a switchboard when thetransformer power rating is increased.

Integration in a communications network

Masterpact can be integrated in a general supervision system to optimiseinstallation operation and maintenance. The communication architectureis open, and may be upgraded for interfacing with any protocol.

Switch-disconnector versions

The switch-disconnectors are derived directly from the circuit breakersand offer the same features and performance levels. They are available inHA, NA and HF versions, depending on the models. The HF versionincludes instantaneous protection to prevent closing on a short-circuit.Once closed, the switch-disconnectors are unprotected and behave likeordinary switches. They are often used for busbar coupling.

The smallest circuit breakerin the world

Masterpact NT innovates by offering all theperformance of a power circuit breaker in anextremely small volume. The 70 mm pole pitchmeans a three-pole drawout circuit breaker canbe installed in a switchboard section 400 mmwide and 400 mm deep.

Practical installation solutionsThe new range improves upon all theinstallation solutions which have already madeMasterpact a success. It has been designed tostandardise switchboards, optimise volumesand simplify installation:c incoming connection to top or bottomterminals;c no safety clearance required;c connection:v horizontal or vertical rear connection;v front connection with minimum extra space;v mixed front and rear connections;c 115 mm pole pitch on all versions;c no derating up to 55 C and 4000A.

Optimised volumes

Up to 4000 A, Masterpact NW circuit breakersare all the same size, the same as the old M08to 32 range.

From 4000 A to 6300 A, there is just one size,much smaller than before.

Retrofit solutionsSpecial connections are available to replace afixed or drawout Masterpact M08 to 32 with aMasterpact NW, without modifying the busbarsor the door cut-out.

Greater dependabilityFiltered breakingThe patented new design of the arc chutes includes stainless-steel filters.The chutes absorb the energy released during breaking, thus limiting thestresses exerted on the installation. They filter and cool the gasesproduced, reducing effects perceptible from the outside.

Automatic unlatchingThe automatic unlatching of the circuit breaker operating mechanism forhigh short-circuits extends performance up to 150kA. It produces ultra-fast tripping for all short-circuits higher than 37 kA (L1) and 65 kA (H3).For lower short-circuits, the system does not react so that the control unitcan provide total discrimination with downstream devices.

More intelligent trip unitsToday, with the high speed of calculation, the small size of memories andadvances in miniaturisation, trip units have become circuit breaker controlunits offering increasingly powerful functions. They accurately measuresystem parameters, instantly calculate values, store data, log events,signal alarms, communicate, take action, etc. The new Masterpactranges, equipped with Micrologic control units, constitute both anextremely reliable protective device and an accurate measurementinstrument.

User friendlyIntuitive useMicrologic control units are equipped with a digital LCD display used inconjunction with simple navigation buttons. Users can directly accessparameters and settings. Navigation between screens is intuitive and theimmediate display of values greatly simplifies settings. Text is displayed inthe desired language.

backed by incomparable securityProtection functions are separate from the measurement functions andare managed by an ASIC electronic component. This independenceguarantees immunity from conducted or radiated disturbances andensures a high degree of reliability.A patented double setting system for protection functions establishes:* a maximum threshold set using the control-unit dials;* fine adjustments via the keypad or remotely. The fine adjustments forthresholds (to within one ampere) and tripping delays (to within a fractionof a second) are displayed directly on the screen.The control unit cover can be lead-sealed to prevent uncontrolled accessto the dials and protect the settings.

Ready forthe futureCompliance withenvironmental requirements

Schneider Electric fully takes into accountenvironmental requirements, starting right from thedesign phase of every product through to the end ofits service life:c the materials used for Masterpact are notpotentially dangerous to the environment;c the production facilities are non-polluting incompliance with the ISO 14001 standard;c filtered breaking eliminates pollution in theswitchboard;c the energy dissipated per pole is low, makingenergy losses insignificant;c the materials are marked to facilitate sorting forrecycling at the end of product service life.

Simple upgrading ofinstallations

Installations change, power levels increase, newequipment is required and switchboards must beextended. Masterpact is designed to adapt to thesechanges:c all control units are interchangeable;c communication with a supervision system is anoption that may be added at any time;c a reserve chassis can be pre-addressed so thatsystem parameters do not have to be modified whena drawout device is installed at a later date;c any future changes to the products will bedesigned to ensure continuity with the currentranges, thus simplifying installation upgrades.

Control unitsMicrologic P power


Micrologic P control units include all thefunctions offered by Micrologic A.In addition, they measure voltages andcalculate power and energy values.They also offer new protection functionsbased on currents, voltages, frequency andpower reinforce load protection.

Protection settings........................................................ + The adjustable protection functions are identical to those of Micrologic A(overloads, short-circuits, earth-fault and earth-leakage protection).

Double settingWithin the range determined by the adjustment dial, fine adjustment of thresholds(to within one ampere) and time delays (to within one second) is possible on thekeypad or remotely using the COM option.

IDMTL settingCoordination with fuse-type or medium-voltage protection systems is optimised byadjusting the slope of the overload-protection curve. This setting also ensuresbetter operation of this protection function with certain loads.

Neutral protectionOn three-pole circuit breakers, neutral protection may be set using the keypad orremotely using the COM option, to one of four positions: neutral unprotected (4P3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t) andneutral protection at 2 In (4P 3t + 2N). Neutral protection at 2 In is used when theneutral conductor is twice the size of the phase conductors (major load imbalance,high level of third order harmonics).On four-pole circuit breakers, neutral protection may be set using a three-positionswitch or the keypad: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t+ N/2), neutral protection at In (4P 4t). Neutral protection produces no effect if thelong-time curve is set to one of the IDMTL protection settings.

Programmable alarms and other protection ......................Depending on the thresholds and time delays set using the keypad or remotelyusing the COM option, the Micrologic P control unit monitors currents and voltage,power, frequency and the phase sequence. Each threshold overrun is signalledremotely via the COM option. Each threshold overrun may be combined withtripping (protection) or an indication carried out by an optional M2C or M6Cprogrammable contact (alarm), or both (protection and alarm).

Load shedding and reconnection........................................Load shedding and reconnection parameters may be set according to the power orthe current flowing through the circuit breaker. Load shedding is carried out by asupervisor via the COM option or by an M2C or M6C programmable contact.

Measurements .......................................................................The Micrologic P control unit calculates in real time all the electrical values (V, A,W, VAR, VA, Wh, VARh, VAh, Hz), power factors and crest factors.The Micrologic P control unit also calculates demand current and demand powerover an adjustable time period. Each measurement is associated with a minimeterand a maximeter.In the event of tripping on a fault, the interrupted current is stored. The optionalexternal power supply makes it possible to display the value with the circuit breakeropen or not supplied.

Histories and maintenance indicators ................................The last ten trips and alarms are recorded in two separate history files.Maintenance indications (contact wear, operation cycles, etc.) are recorded forlocal access.

Indication option via programmable contactsThe M2C (two contacts) and M6C (six contacts) auxiliary contacts may be used tosignal threshold overruns or status changes. They can be programmed using thekeypad on the Micrologic P control unit or remotely using the COM option.

Communication option (COM)The communication option may be used to:c remotely read and set parameters for the protection functionsc transmit all the calculated indicators and measurementsc signal the causes of tripping and alarmsc consult the history files and the maintenance-indicator register.An event log and a maintenance register, stored in control-unit memory but notavailable locally, may be accessed in addition via the COM option.

Demand meteringThe demand is calculated over a fixed or sliding time window that may beprogrammed from 5 to 60 minutes. According to the contract signed with the powersupplier, an indicator associated with a load shedding function makes it possible toavoid or minimise the costs of overrunning the subscribed power. Maximumdemand values are systematically stored and time stamped (maximeter).

Software

DevicesCircuit breakers equipped with Micrologic control units may be connected to eithera Digipact or Modbus communication bus. The information made availabledepends on the type of Micrologic control unit (A, P or H) and on the type ofcommunication bus (Digipact or Modbus).Switch-disconnectors may be connected exclusively to the Digipact communicationbus.

Communication bus

DigipactThe Digipact bus is the internal bus of the low-voltage switchboard in which theDigipact communicating devices are installed (Masterpact with Digipact COM,PM150, SC150, UA150, etc.). This bus must be equipped with a DC150 dataconcentrator (see the Powerlogic System catalogue).

AddressesAddressing is carried out by the DC150 data concentrator.

Number of devicesThe maximum number of devices that may be connected to the Digipact bus iscalculated in terms of communication points. These points correspond to theamount of traffic the bus can handle. The total number of points for the variousdevices connected to a single bus must not exceed 100.If the required devices represent more than 100 points, add a second Digipactinternal bus.

Communicating device Number of pointsDC150 data concentrator 4Micrologic + Digipact COM 4PM150 4SC150 4UA150 4

Length of busThe maximum recommended length for the Digipact internal bus is 200 meters.

Bus power sourcePower is supplied by the DC150 data concentrator (24 V)..


ModbusThe Modbus RS485 (JBus) system is an open bus on which communicatingModbus devices (Masterpact with Modbus COM, PM300, Sepam, Vigilohm, etc.)are installed. All types of PLCs and microcomputers may be connected to the bus.

AddressesThe software layer of the Modbus protocol can manage up to 255 addresses (1 to 255).The device communication module comprises three addresses linked to:b circuit-breaker manager;b measurement manager;b protection manager.The craddle communication module comprises one address linked to:b the craddle manager.The division of the system into four managers secures data exchange with thesupervision system and the circuit-breaker actuators.The manager addresses are automatically derived from the circuit-breaker address@xx entered via the Micrologic control unit (the default address is 47).
