1. Warnings
Warnings:
During operation, electrical equipment carries
dangerous voltages. In addition, circuit breaker
emits hot, ionized gases when switching
currents, especially short circuit currents.
Installing, commissioning, maintaining, changing
or refitting of this equipment must be carried out
only by qualified and suitably trained personnel
and under strict observation of national and
international applicable safety regulations.
During their operation, circuit breakers must be
equipped with appropriately fitted covers, e.g. in
suitable enclosures or panel boards. Safety
distances must be preserved. Suitably trained
service personnel shall only carry out certain
works.
Non-compliance with these warnings may result
in death, and/or severe physical damage and
extensive damage to equipment.
Prior to carrying out maintenance, inspection or
checks, the circuit breaker must be open, the
both terminals must be grounded, the circuit
breaker must be switched off and the control
plugs removed.
Manual activation of the breaker while energized
is forbidden. Manual activation must only be
used for maintenance and inspection purposes,
when breaker power is off and grounded.
The circuit breaker consists of high energy
moving components. Do not touch the circuit
breaker while it is being switched ON (closing) or
OFF (opening). There is a high risk of major injury.
The control circuits may include capacitor banks,
which can be charged with dangerous voltages.
Work on this section must be carried out
carefully.
2. General usage conditions
2.1 Transportation and storing
• The breaker is transported on wooden palette. It is fixed
by shrunken plastic film. A cardboard box covers the
breaker on the palette. Truck, railway, airplane and ship
transport is possible. In case of sea transport, special
protection against salty and humid environment is
provided.
• The circuit breaker must always be transported to the
installation site vertically and fully packed. The packaging
protects the device against damage and dust; it should
only be removed prior to installation.
• If the packaging is damaged, the breaker and the arc
chute must be inspected for damage. Ensure that all
packaging materials have been carefully removed prior to
breaker installation.
• For handling the unpacked breaker use the lifting rings
provided [Fig.0]. The rings are located on both sides of the
breaker. For lifting, it is recommended to use 4-leg wire
rope slings of 1 m length (max. 8mm diameter) or 4-leg
chain slings of 1.5 m length (max. 20 mm chain diameter).
Lifting rings
Fig. 0 Lifting rings for handling the breaker
• WARNING: Breaker and arc chute must be transported
separately. Never handle the breaker with arc chute
installed!
• Take care that the bottom isolation plate of the unpacked
breaker is not damaged during handling. Do not push the
breaker back and forth on any rough surface.
• The breaker’s weight, including arc chute is listed in Table
1. Arc chute’s weight is approximately 30 kG (66 lb) for
“1x_” type.
WARNING:
• Store in original packaging!
• Do not store outdoors!
• Use protection against crush and impact!
• Do not store the breaker in a damp area!
• Storing temperature-range –25 °C…+60 °C!

2.2 Installation
2.2.1 Operational environment
• The breaker, as delivered, is IP00 (NEMA 1) protected. It is
intended to work in indoor applications, without
pollutions, with non-conductive dust, protected against
high humidity and condensation. Low conductivity dust
deposit due to frequent condensation of humidity is
acceptable. General environmental conditions refer to EN
50123-1 - annex B, and IEC 60947, class PD3.
• The breaker can operate at rated current within ambient
temperature range of –5 °C to +40 °C (23 to 104 °F).
Maximum operating ambient temperature is +55 °C
(130 °F) with continuous current derated by 10 %.
• The breaker can operate at altitude up to 2000 m
(~6500 ft) without derating.
• The breaker shall not be subjected to strong vibrations.
Maximum vibrations of 0.5 g per 30 sec are allowed.
Resonance frequency is in range of 31 to 33 Hz.
• Air shall be clean and its relative humidity shall be not
more than 50 % r.h. at the maximum temperature of
+40 °C (104 °F). Relative humidity may be higher if the
temperatures are lower, for example, 90 %r.h. at +20 °C
(68 °F). Slight condensation might occur during variations
of temperature
2.2.2 Installation and interfaces
• The lower and upper main terminals (Code 4) must be
connected directly to the main cables or bus bars.
• WARNING: The breaker must only be used in an upright
operation position with the arc chute in place and fully
secured.
• After arc chute installation check for tightness both
connections to the arc probes.
• The safety distances as listed in Table 4 shall be
maintained to grounded or insulated parts. Suitable
measures must be taken to protect personnel from arcs.
• Strong, external magnetic fields, caused by improperly
located supply conductors or stray fields from other
devices, can lead to a shift of the trip setting thresholds.
This may result in premature tripping, or no tripping at all.
This has to be accounted for when installing and
operating the device with shielding added if appropriate.
• The control wires must be connected to the control
terminals (Code 19), as shown in the schematic circuit
diagrams in section 4. The protective grounding wire must
be connected at the terminal –X2:3. This point is a
common grounding for the drive and control box.
2.3 Usage
2.3.1 Supply and load
• The breaker has polarized main connections. The marks
are stamped at the ends of the main connections [Fig. 1].
The normal current flow, forward direction, is from plus to
minus terminals and does not cause breaker to trip. The
reverse current flow, from minus to plus, does cause the
breaker to trip.
• In accordance with its type, the breaker has been
designed for the current and voltage listed in Table 1.
• During continuous operation, breaker must only be
loaded up to its maximum rated current. Load currents in
excess of breaker nameplate rating are allowable for brief
periods. Refer to the short time currents listed in Table 1.
• Do not exceed the rated operating voltage shown on the
breaker’s nameplate.
• Supply voltage for the drive and the auxiliary-tripping
devices (Code 8) shall be within the specified control
voltage range. Maximum current values for the auxiliarytripping devices are listed in Table 2a.
• WARNING: Plugging in or unplugging of the auxiliary
connectors (-X2 :1/:2) (-X3 :4/:5) is only allowed with
disconnected primary (mains) and secondary voltages.
2.3.2 Adjusting the over current release
• POCT is a polarized over-current tripping release (Code 7),
which trips and releases the breaker in case of over
currents for one direction only.. This is an instantaneous
and direct acting device.
• If equipped with an adjustable POCT, the response
threshold can be easily adjusted [Fig.2], by turning the
adjustment nut 1 with a SW6 hexagon wrench 2.
• The adjustment must only be carried out after the breaker
has been disconnected from the main circuit. For fixed
installations breaker’s main terminals shall be grounded.
• Turning the adjustment screw clockwise increases the trip
threshold, turning the screw counter-clockwise decreases
the tripping threshold.
• Align the arrow and the desired marking 3, to perform
adjustment.

3. Technical information
3.1 Introduction
• Gerapid R-type (rectifier type) is a single pole, high-speed
DC circuit breaker, designed for use in railway propulsion
power distribution systems with operating currents up to
8000 A (Code 1) and operating voltages up to 1200 V
(Code 2).
• Gerapid breaker has a very high interruption capacity
combined with a current limiting characteristic. The arc
chute works on the basis of an asbestos-free arc splitting
principle.
• A wide variety of accessories and spares are available for
maintenance, repair, or as a possible enhancement.
• Use the catalogue coding system described in section 7.1
to configure the breaker. Each rating, option or accessory
has own code.
• Closing of the circuit breaker is performed through a highpower solenoid drive (Code 3).
• During inspections, opening and closing may be carried
out by means of a hand lever (Code 16), which is mounted
onto the armature of the closing drive.
• Tripping and release is obtained directly by means of the
POCT release (Code 7), or optionally by ED impulse release
(Code 12). Indirect remote tripping can be achieved by
means of a shunt trip, or optionally by a zero voltage
release (Code 11).
• Gerapid breakers have a compact and enclosed
construction. Gerapid is IP 00 protected. All parts are
mounted on thick-walled, non-breakable and fireproof
insulation panels.
3.2 Components and accessories
3.2.1 Contact system
• Gerapid breakers are equipped with a two-stage contact
system [Fig. 3], consisting of a main contact and an
arcing contact. With this proven design, the main contact
is not subjected to any appreciable wear or tear. Each
breaker has two such contacts, working as a single pole.
• The main contact is made of a silver composite material.
The arcing contact and link braid are made of copper and
can be easily replaced.
• The flexible bend is linked to the arcing contact by means
of very tight braid.
3.2.2 Arc chute (Code 2)
• Compact and modular design of the arc system requires
no additional magnetic blow out support and allows small
safety distances with high breaking capacity.
• An adaptor [Fig. 1] is used to mount the arc chute on the
breaker.
• The arc chutes consist of a highly durable, arc-proof
material, in which the arc plates have been integrated.
• The arc plates split the arc into partial arcs and increase
the arcing voltage by multiplying the anode and cathode
voltage drop. Because of their high heat capacity, the
plates and arc chute walls absorb a large amount of the
arc’s energy.
3.2.3 Mechanism
• Gerapid is equipped with a modular designed mechanism,
which is wear-resistant and nearly maintenance-free.
This mechanism ensures an extended electrical and
mechanical endurance of the breaker as well as a high
level of safety under all operation conditions.
• The breaker is rated for 10 000 operations when opened
by the shunt trip or zero voltage release, and 500
operations by means of ED impulse coil or POCT releases,
before maintenance should be required.
• The mechanism is mechanically latched in the CLOSED
position. The principle of a mechanically latched
mechanism offers an advantage compared to often used
electro magnet holding system. No auxiliary control
power source is required to keep breaker closed.
• The mechanism is provided with two tripping latches
[Fig. 4]. First latch, called “slow latch”, is used for opening
under normal conditions, like actuation of shunt trip or
zero-voltage release. The second one, “quick latch”, declutches the main contact arm from the mechanism and
opens the contacts with an extremely short delay. This is
used when interrupting short-circuit or overloads. All
safety releases operate onto “quick latch” latch.
• The mechanisms in rectifier breakers are the same type,
but different from standard, feeder breakers mechanisms.
Therefore mechanisms cannot be exchanged between
rectifier and feeder breakers.

Fig. 4 Latching and tripping system
6 Design and specifications are subject to change without notice DTR01807 rev.02 2010-02-16
3.2.4 Polarized over current release (Code 7)
• The POCT release is a magnet with two magnetic circuits.
The first one (tripping yoke) provides bi-directional
tripping function. The second one (blocking yoke) provides
unidirectional blocking function.
• This technology ensures fast tripping in reverse current
direction and no tripping in case of forward current. This
system does not require an auxiliary control voltage or
protection relay to operate. It is a direct acting and
instantaneous tripping device.
• The tripping yoke [Fig. 7] consists of the holding circuit [6],
the movable armature [3] and the tripping circuit [7]. The
holding and the tripping magnetic circuits are both
excited by load current [1]. Until the static overload
release’s response threshold has been reached, the
armature [3] is held in position by the holding flux (ΦH) [2]
and the counter spring’s force [4]. Once the load current
exceeds the set static response threshold, the attraction
flux (ΦA) [2] takes over and rapidly pulls down the flexible
armature [3]. During this operation, the armature hits the
seesaw, which releases the quick latch in the mechanism.
The latch and contacts are opened immediately.
• The response threshold can be easily adjusted by turning
the adjustment nut with a SW6 hexagon wrench. The
available ranges are described below. Other ranges might
be possible on request.
• The blocking system of POCT consists of main magnet
circuit, permanent magnet oscillator and blockades. If the
main current in forward direction exceeds 250A, the
locking system starts to operate and counteracts tripping.
This makes the breaker a unidirectional device.
• Following tripping ranges are available: 0.4-1.2 kA; 0.8-
2.5 kA; 2.0-6.0 kA; 4.0-8.0 kA.

3.2.5 ED impulse coil release (Code 12)
• To detect high short circuit currents early and to record
leakage currents in long peripheral sections (for railway
equipment), whose final values are lower than the highest
operating currents, protective relays for monitoring a
current increase should be utilized. If a fault occurs, a
release signal can be passed on to the ED impulse coil
and capacitor release (NEKO), which causes the breaker
to open rapidly (opening delay <3ms).
• This tripping device can be ordered as an accessory for
the breaker, either alternatively, or additionally to a shunt
trip or a zero voltage release.
• ED impulse release requires an external protective relay
for monitoring a current increase. This relay must be
provided and installed by the customer.
• Customer supplied capacitor trip unit may be used. Rated
voltage of 300 V and capacity of 2 000 µF per coil is
required. Rectifier breakers utilize two ED coils.
• WARNING: ED Firing signal voltage level is between 6 V
and 24 V. There should be no spikes on the signal of
duration less 3 ms. This can lead to failure of the NEKO
board!
• WARNING: Maximum duration of the firing signal must
not exceed ~1 sec. Longer signal can lead to NEKO
overheating! It is recommended to use an auxiliary
contact in serial connection with firing circuits. It will
automatically cut off the firing circuits after opening.
3.2.6 Auxiliary tripping devices (Code 11)
• The breaker can be equipped with either a shunt trip (ST,
a-release) or a zero voltage release (UVR, r-release).
• Both trips work at a voltage level of 24VDC. A voltage
transformer, which is integrated into the breaker, adapts
to other voltage levels and provides the energy required
by the breaker mechanism (except for the drive).
• Optionally, it’s possible to supply both devices directly to
external 24 V DC ( ± 5%). In this case the release signal for
ST shall not be longer 100 ms.
• The shunt trip is used for remote actuation. It is designed
for intermittent operation (ED=9%) and is always
connected through an auxiliary contact to ensure that is
only energized during the time until the breaker is
opened.
• The UVR’s winding is designed for continuous operation.
In case of a control voltage drop, the release mechanism
opens the breaker. It is therefore possible to use the
release in combination with the electronic trip unit for
voltage monitoring, i.e. for motor starters, where an
unintended re-start of a motor after a temporary voltage
breakdown is to be prevented. Due to their operational
mode, UVRs are self-monitoring devices, i.e. the breaker is
tripped upon a break of the pilot wire (EMERGENCY-OFF
principle).
• WARNING: Manual closing of the breaker with shunt trips
installed, while signal OPEN is active and control power is
applied, may lead to shunt coil overheating and damage.

2010-02-16 DTR01807 rev.02 Design and specifications are subject to change without notice 7
3.2.7 Forced tripping release (Code 13)
• Optionally, the forced tripping release (FT) can be installed
in the breaker [Fig. 6]. This mechanical trip releases the
breaker, by pressing the pin located in the bottom plate.
Force required to trip the breaker is about 110 N (~25 ftlb). The tripping pin position is shown on Fig. 6.
• WARNING: This device, when active, does not prevent
breaker from closing. Closing the breaker against
activated FT may lead to damage of this release.
• With a correctly designed interlock in an enclosure, FT
provides safety-tripping function. During withdrawal
operation of the trolley, the breaker is tripped BEFORE its
main terminals disconnect from the bus.
Bottom view
Fig. 6 Forced tripping release
3.2.8 Lever for manual operating (Code 16)
• Optionally, a hand lever for manual closing and opening
operation during maintenance is available. This tool must
not be use while breaker is energized!
• To close the contacts, install hand lever (1) on the drive’s
rod, and pull it out smoothly until latches snap [Fig. 7].
Safe manual closing is shown on the Fig. 26, chapter 6.1.2.
• To open the contacts, insert lever’s pin (3) into the ring (2)
and push it hard until breaker opens [Fig. 8] and [Fig 27].
• WARNING: Manual closing and opening – only during
maintenance!
• Alternative manual closing and opening operation is
possible by rotating the main shaft of the breaker
mechanism, which is accessible from both side. Use
10 mm hexagon-box wrenches to OPEN/CLOSE [Fig. 9]. To
close the breaker, shafts from both sides have to be
rotated simultaneously.
• WARNING: Pay attention to control rotation speed of the
shaft during manual opening and closing. Impede the
wrench to avoid hitting it to the ground, which may lead
to a hand injury.

3.2.9 Auxiliary switches (Code 9)
• The breaker can be equipped with up to nine isolated
form C auxiliary contacts (1 NO/NC each) [Fig. 10]. The
contacts are activated by breaker’s main mechanism.
• The contacts are wired to 15-pin control plugs: -X4 and X5, with 5 switches to each plug.
• Conventional thermal current Ith=10 A. Maximum
electrical interrupting ratings for switches are 1 A/230 V
for AC15. For DC13 are 0.5 A/110 V and 0.3 A/220 V.
Fig. 10 Auxiliary switches block in the control box.
3.2.10 Indicators
Optionally, the circuit breaker can be equipped with
following indicators:
• POSITION INDICATOR (Code 14) - mounted at the front of
the closing drive [Fig. 12]. Moving drive’s rod is
mechanically switching the indicator.
“OPEN” or “O” – means open main contacts
“CLOSED” or “I” – means closed main contacts
• OC TRIP TARGET (Code 10) – a potential free, NO contact
mounted at the top of the OCT [Fig. 14]. Provides a signal
when OCT trips.
• ARC CHUTE INDICATOR (Code 17) – a potential free, NO
contact mounted on the sidewall, item (1) on Fig. 11. Locks
electrically the closing drive when arc chute is not
installed on. The signal is available at terminal –X3 :12:13.
3.2.11 Solenoid closing drive (Code 3)
• The closing drive is mounted at the front of the breaker
and is encased in a grounded casing [Fig. 12].
• The closing drive includes a self-interrupt control circuit
(SU PCB). This circuit enables a short activation with
minimum command duration of approximately 100ms,
causing the voltage applied to the solenoid to be switched
off after approximately 400ms and prevents, during
continuous operation, repeated reclosing (anti-pumping)
due to an existing short circuit.
• Closing drive is supplied independently from other
controls (-X2 :1/:2), directly from external power source.
Voltage level must be defined at order placement. Rated
power, depends on breaker type, is 3 kW or 4.5 kW.
• After closing attempt, the switch-in mechanism is
electrically blocked for approximately 8 sec. Lock time
increases to 14 sec, if internal C-bank (NEKO) is present.
This prevents premature closing following a short circuit.

3.2.12 Electronic control system
All the control PCBs are installed in control box [Fig. 13].
Starting from the left, these are:
Fig. 13 Control box with control PCBs.
• (1) NEKO control unit [Fig. 13-1] (Code 12) – internal
control unit with capacitor bank. Releases firing signal for
ED coil and provides indication of the capacitors charging.
NEKO control unit also blocks the firing signal until C-bank
is fully charged (~15 sec).
• WARNING: NEKO unit requires a high quality signal. Be
sure, that voltage level is between 6 V…24 V DC and there
are no short spikes on signal (<3 ms). This may lead to
major defect of the NEKO control unit!
• (3) SU control unit.
