ME07 - Air circuit breakers
Fixed circuit breaker
Description
The circuit breaker Series ME is provided with an engaged latch
mechanism with a trip-free feature housed in a steel frame construction.
They are equipped with a hand operated drive mechanism, an electronic
trip unit and auxiliary contacts. On request a wide range of accessories e.g.
motor operated drive mechanism, auxiliary trips etc. can be ordered.
The disconnecting switch Series MET is identical with the circuit breaker
but non automatic.
Degree of protection IP00, however IP54 can be achieved with an additional
sealing kit for the door cut-out.
Terminations are available at the rear in horizontal or vertical plane, the
design is interchangeable (ME637 to ME3207). Horizontal connection for
stationary mounting and withdrawable technique are the same
(ME1607 to ME3207).The devices ME4007/5007 are equipped with
horizontal terminals.
Installation
Base or rear mounting (vertical or horizontal traverse) is possible without
additional parts. In combination with rear mounting and vertical terminations
the use of two angular spacers is necessary to ensure the required
creepage and clearance distances (ME637 to ME3207).
The devices ME4007 to ME5007 allow only rear side mounting.
Power supply
Either on the upper or on the lower terminals.
Wiring of control circuits on plug- and socket connectors, finger-safe.

ME07 - Air circuit breakers
Withdrawable circuit breaker
Description
The Series ME withdrawable version consists of the both components
circuit breaker and cradle.
The withdrawable version enables three defined positions
1. Disconnected
Both main and control circuits are disconnected.
2. Test
The main circuit contacts are open and the control circuit contacts are
connected to allow functional tests of the device.
3. Connected
Both main and control circuit are connected.
The main contacts are provided with a full and positive personnel protection.
The position of the circuit breaker within the cradle can be optionally
indicated by position switches for monitoring and electrical interlocking.
A mechanical interlock operates directly on the latch mechanism to prevent
the circuit breaker being inserted or withdrawn in the closed position.
• Rated current up to 3200A
After locating on the integrated telescopic extension rails and locking in
the disconnected position the circuit breaker remains in this position. The
electrical connection of the main circuit is achieved by a separate
movable contact system operated by a cranking handle. It is located in a
movable frame within the cradle. The position of the circuit breaker behind
the switchboard door is independent of the positions disconnected, test
and connected.
The cradle is provided with a positively driven mechanical position
indicator.
• Rated current 4000 to 6400A
After locating on the rails the circuit breaker is inserted or withdrawn by
means of a cranking handle worm drive. For easier service or exchange
of the circuit breaker an optional extension rail is available to draw out the
breaker in front of the cradle.
Installation
• Rated current up to 3200A
Base mounting of the cradle, terminations at the rear in horizontal, vertical
or combined plane. Wiring of the control circuits on plug and socket
connectors on the upper left side, finger safe, accessible from the front.
Automatic contact in the test and connected position. Optional position
indication switches on the upper right side are accessible from the front as
well.
• Rated current 4000 to 6400A
Base mounting of cradle, terminations at the rear in horizontal or
combined (upper horizontal, lower vertical) plane (4000A), in horizontal
plane (5000A and 6400A). Easy wiring of the control circuit contacts and
position indication switches.
Power supply
Either on the upper or on the lower terminals.

ME07 - Air circuit breakers
Electronic trip units type bse
Protection
The electronic trip units offer the protection as specified below:
• Overload, current depending time delay - b-Channel
• Short-circuit, current independent time delay, adjustable - s-Channel
• Short-circuit, instantaneous- k-Channel
• Short-circuit with ZSI - Zone selective interlock. This interlocking
feature monitors the signal states of circuit breakers connected in series
to reduce the pre-set delay time to a minimum and optimise the scheme
for selectivity (see figure below).
• Earth fault, current independent time delay, adjustable - g-Channel
The electronic trip units type bse 3-x rms and bse 4-x rms are designed for
applications in networks with harmonics and comply with the standard
IEC 947-2, Appendix F.
Level A
ME07
Construction
The electronic tripping system consists of the components
• trip unit and
• current transformers.
The components are separately integrated into the circuit breaker. The
current transformers supply the protection device of the trip unit and
generate the output signal for the measuring unit.
Level B
ME07
Signalling line
The principle of construction and function is shown in figure below.
Level C
ME07
Block diagram ZSI - Zone selective interlock
The trip units are available for 3 and 4 pole circuit breakers. The adaptation
to the different rated currents is realised by the corresponding current
transformers.
The sampler receives the output signal from the current transformer and
transfers the information to the Analog - Digital - Converter. The processing
unit analyses the signal and compares the results with the parameter
settings. In case of a fault condition, e.g. overload, the activator will be
energised to trip the circuit breaker.
The current transformer output signal for each phase is sampled 15 times
per cycle in order to establish a TRUE RMS value of the current
independent of the network, type of load or installation.
12
The current transformer for the 4th pole of the trip unit is fitted inside the 4
pole version of the circuit breaker. On request a separately mounting outside
the breaker e.g. in the neutral phase is possible. Then the connection
between current transformer and trip unit must be field installed by applicant.
Contacts for TRIP indication are provided as well as TRIP indication LED’s
for types bse 3/4-3 rms to bse 3/4-6 rms.
For additional functions like indication, parameterizing, messages and BUSconnection (if available) an auxiliary power supply is necessary.

ME07 - Air circuit breakers
Drives
The drive mechanism with an energy storage facility is equipped with
integral service facilities for immediate actuation without any additional
coupling parts, e.g. through a door cut-out. Opening and closing action of
the circuit breaker is made by pushbuttons. A positive operated indicator of
the switch position and spring charge condition is provided along with a wide
field of visibility to the trip unit.
Mechanism: ON operation mechanically with ON pushbutton or electrically
with closing coil.
OFF operation mechanically with OFF pushbutton or electrically
with
undervoltage- or shunt trip.
Interlock with cylindrical lock or padlock
All mechanisms provided with a closing coil are suitable for synchronisation
applications.
Manual operated mechanism with storage type x2, xv
The spring energy storage is charged by a pumping handle. The closing
action is performed mechanically by means of the ON pushbutton or
electrically by actuating the closing coil from a remote position.
Indication switch type m3 - Spring energy system charged - optional
Indication switch type m4 - Breaker ready for closure - optional
Motor operated mechanism with storage type fv and
automatic control unit
The spring energy storage is charged by a motor drive. The automatic
control unit operating with a short control impulse (app. 20 ms) disconnects
the motor from supply after the spring is charged. The remote ON-operation
is performed by actuating the closing coil. Manual charging and ON or OFF
operations are possible as well.
The indication “Spring energy system charged“ is included in control unit,
indication switch type m4 - “Breaker ready for closure” is optional available.
Five charging modes are available which can subsequently be changed in
the field
