For connection of auxiliary circuits, the circuit breakers of fixed version are equipped with manually plug-in
terminal boards with coding pins, which eliminate misuse of the terminal boards in their connecting with
the block of the citcuit breaker blade contacts.The contacts of auxiliary circuits of circuit breakers of
withdrawable version are inserted automatically in circuit breaker moving into the frame.
Conductors of auxiliary circuits are connected to terminal boards in two ways (see the figure).

Overcurrent protection settings
Adjust parameters only when the circuit-breaker is switched off. If the
parameters are modified with the circuit-breaker switched on, this can
!trip the circuit-breaker unintentionally.
All parameters are adjusted with rotary coding switches.
3 x 0,5
The value 0,1 is set
if the rotary switch is
positioned in this zone.
Protective functions
- overload protection (L-tripping)
- short-time-delay short-circuit tripping (S-tripping)
- instantaneous short-circuit tripping (I-tripping)

For charging the spring mechanism pull the handle and return the handle
!completly up to the stop.
b) by motor operating mechanism:
Motor operating mechanism starts automatically after applying control voltage.
The motor is automatically de-energized at the end of the charging operation.

MAINTENANCE
Contact assemblies need to be changed according their condition, but at least after:
-10 000 Operations in FSI and FSII;
-5 000 Operations in FSIII;
-1 000 Operations in FSII and FSIII when used in 1000 V appliances
The switchgear operator has to be determine inspection intervals depending on the breaker
applications:
-min. 1x per annum
-after interruption of heavy loads
-after trips by the overcurrent release (trip unit)
-down stream connected non-automatic circuit breakers have to be inspected also
During the inspection and/or after 1000 switching operations, the following items must be examined
(max. operations see catalog):
-arc chutes and contact systems
-electrical and mechanical functionaliy of the breaker
-mechanical on- / off-functionality
-main and auxiliary circuits, function and connecting quality
-plausibility control of trip unit settings and correction, if necessary
If the breaker endurance is exhausted, then the breaker and old spare parts are to be disposed of,
according to the effective legal regulations.
Draw-Out guide frames with arc-chute covers installed, have to be replaced after no more than three
schort-circuit interruptions of the circuit-breaker.
The arc chutes and the contact system must be replaced depending upon their condition, but latest after
10,000 switching operations.
Depending on the circuit-breaker stress it may also be necessary to replace the operating system after
10,000 switching operations.
The attached CD contains more detailed operating instructions.
Only materials which have low adverse environmental impact and which do not contain dangerous
substances as specified in ROHS directive have been used in the product.
