1.2 Technical Data

Table 1 Technical data for Gerapid 2607 - 8007with arc chute 1X2.

1.3 Short DescriptionGerapid high-speed DC circuit breakers aresingle-pole circuit breakers designed for use inrailway propulsion-power distribution systemswith operating currents up to 6000 A andoperating voltages up to 800V dc. They have avery high interruption capacity combined with acurrent limiting characteristic.

Closing of the circuit breaker is performed througha high-power activation magnet. Duringinspections, opening and closing may be carriedout by means of a hand lever, which can bemounted onto the armature of the activationmagnet.Overload tripping is achieved directly via a shortcircuit trip or, depending on the rate of currentrise, by an external current-rise release with aninternal capacitor trip (ed - trip available as anaccessory). Indirect remote tripping can beachieved by means of a shunt trip or anundervoltage release.The arc chute works on the basis of a highlysophisticated, asbestos-free, arc splittingprinciple.A wide variety of accessories and spares parts isavailable for maintenance, repair, or possibleextension.

1.4 Structure and ComponentsType Gerapid high speed DC circuit breakershave a compact and enclosed construction. Theyare IP 00 protected. All parts are mounted onthick-walled, non-breakable and fireproofinsulation panels, whose large covers protect thebreaker’s mechanism from damage. Transparentplastic side covers are available as an optionalaccessory to protect metal connecting elementson the panel.

Gerapid breakers are equipped with a two-stagecontact system. The main contacts are coated with asilver composite material; the arcing contacts are madefrom copper and can be easily replaced. The flexiblecontact is linked to the connection by means of verytight braids.

An attachment set is used to mount the various arcsplitting systems for different operating voltages to thebreakers. The arc chutes consist of a highly durable,arc-proof material, into which the arc plates have beenintegrated. The arc plates of split the arc into partialarcs and increase the arcing voltage by multiplying theanode and cathode voltage drop. Because of their highheat capacity, the plates and arc chute walls absorb alarge amount of the arc’s energy.

The overload trip design uses a release magnet withtwin magnets, optimizing the twin magnetic fieldprinciple. This technology ensures equally fast trippingin both current directions. The magnetic system doesnot require an auxiliary voltage. The system consists ofthe holding circuit, the flexible armature and the trippingcircuit. The holding magnet and the tripping magnet areboth excited by the main current.Until the static overload release’s response thresholdhas been reached, the flexible armature is held inposition by the holding circuit’s magnetic field and thecounter spring. If the main current exceeds the setstatic response threshold, the tripping circuit’s powertakes over and pulls the flexible armature downsuddenly. During this operation, the armature trips therelease lever. The main latch and contacts are openedimmediately. The response threshold can be easilyadjusted by turning the adjustment nut with a SW6hexagon wrench. In combination with the transparentside cover accessory, a fixed-mounted insulated knobis available (accessory).

To detect high short circuit currents early and to recordleakage currents in long peripheral sections (for railwayequipment), whose final values are lower than thehighest operating currents, protective relays formonitoring a current increase should be installed. If afault occurs, a release signal can be passed on to thecapacitor release, which causes the breaker to openrapidly (opening delay <3ms). This tripping mechanismcan be ordered as an accessory for the breaker.(Alternatively, or additionally, it is possible to activate ashunt trip or an undervoltage release).

The breaker can be equipped with either a shunttrip or an undervoltage release. The shunt trip canbe used for remote actuation. The undervoltagerelease can be used for remote actuation and, incombination with an optional electronic trip unitincorporated into the breaker, for voltage control.Both trips work on a voltage level of 24V. Avoltage transformer, which is integrated into thedevice, adapts to other voltage levels bytransferring the energy required by the breakermechanism (except for the drive). The releasemechanism is tripped by potential free contactsat 24V level. The shunt trip is designed for shorttime action and is always connected through anauxiliary contact. This ensures that the shunt tripis only energized during the time until the breakeris opened. The undervoltage release’s winding isdesigned for continuous operation. In case of avoltage drop, the release mechanism opens thebreaker. It is therefore possible to use the releasein combination with the electronic trip unit forvoltage monitoring, i.e. for motor switches, wherean unintended re-start of machines after atemporary voltage breakdown is to be prevented.Due to their operational mode, undervoltagereleases are self-monitoring devices, i.e. when thebreaker is tripped upon a break of the pilot wire(EMERGENCY-OFF principle).

The activation magnet is mounted at the front ofthe breaker and is equipped with a groundedcasing. The drive includes a self-interrupt controlcircuit (SU-control). This circuit enables a shortactivation with a minimum command duration ofapproximately 300 ms, causing the voltageapplied to the magnet to be switched off afterapproximately 400ms and prevents, duringcontinuous operation, repeated activation (anti-pumping) due to an existing short circuit. Inaddition, the switch-in mechanism is electricallyblocked for approximately 10s after activation.This prevents premature activation following ashort circuit.

The breaker is equipped with up to ten isolatedform C (1 NO/NC) auxiliary contacts. Theauxiliary contacts are activated by the movablemain contact. They are wired to 15-pin controlplugs. As an accessory, the circuit breaker canbe equipped with auxiliary switches for indicationof short circuit tripping and for the presence of thearc chutes.


2 Installation and Operation

2.1 TransportationThe circuit breaker must always be transported to theinstallation site properly and fully packed. Thepackaging protects the device against damage anddust; it should only be removed prior to installation.If the packaging is damaged, the breaker and the arcchutes must be inspected for damage. Ensure that allpackaging materials have been carefully removed priorto breaker installation.

2.2 InstallationThe breakers, as delivered, are IP00 protected. Theymust be installed in a dry, preferably dust-free room.They must not be subjected to strong vibration.

The lower and upper connections must be connecteddirectly to the main cables and busbars.

The breaker must only be used in an uprightoperating position with the arc chute in place andfully secured. After installation, both the arc chuteand special threaded joints must be checked fortightness.

The safety distances as shown in the dimensionaldrawings [Fig.9,10,11] must be maintained to groundedor insulated parts. Suitable measures must be takento protect personnel from arcs.

Strong, external magnetic fields caused by improperlylocated supply conductors or stray fields from otherdevices, can lead to a shift of the trip settingthresholds. This may result in premature tripping, or notripping at all, during low-level short circuit currentevents. This has to be accounted for when installingand operating the device with shielding added ifappropriate.

The control wires must be connected as shown in theschematic circuit diagram [Fig.23].The protective grounding wire must be connected at themarked terminal.

2.3 Setting the Overload ReleaseThe adjustment of the static overload release [Fig.1]within a specific adjustment range is made by turningthe regulating screw. This procedure requires an SW6hexagon wrench. The adjustment must only be carriedout after the breaker has been disconnected from themain circuit and has been grounded.

Turning the adjustment screw clockwisedecreases the trip threshold, turning the screwcounter-clockwise increases the trippingthreshold. Adjustment is performed by aligningboth the arrow and the marking line to one line.

2.4 OperationMaximum operating voltage and current ratingsare as shown on the breaker nameplate.

During continuous operation, it must be loadedwith its rated operating current at maximum. Loadcurrents in excess of breaker nameplate ratingare allowable for brief periods. Refer to the shorttime currents listed in Table 1. Do not exceedthe rated operating voltage shown on the breakernameplate.

The drive and auxiliary trips function within thespecified control voltage range. The auxiliary tripsmust be loaded with the values listed in Table 1 atmaximum.

Fig.1 Setting the overload release


3 Inspection and Maintenance

Prior to carrying out maintenance, inspection orchecks on the circuit breaker, the breaker must beopen, the connections on both sides must begrounded, the circuit breaker must be switched offand the control plugs removed.Non-compliance with these warnings can result indeath, severe physical damage and extensivedamage to equipment.Metric tools are needed for all screws.

3.1 GeneralRegular inspection and maintenance must be carriedout to ensure the proper functioning of the circuitbreaker and in order to achieve a long working life. Theintervals at which inspections must be carried out maybe determined by evaluating the breaker’s duty cycle.Table 2 provides an overview of checks to be carried outand lists the appropriate inspection intervals. Table 3provides indicators for maintenance work. In order tocheck the latch mechanism, the breaker can beopened and closed with a hand lever.Fig. 2 shows the correct use of the lever.
