19 Operating the panel with circuit-breaker type 2
This chapter describes the manual operation of panels with circuit-breaker type 2 and three-
position disconnector (panel type L).
Motor operating
mechanism (option)
To perform switching operations with the circuit-breaker and the three-position disconnector,
the panels can be equipped with a motor operating mechanism. The use of the motor
operating mechanism is described in the circuit documentation.
Manual switching operations are also possible with motor operating mechanism. If the control
gate is operated in order to perform a switching operation, electrical switching commands to
the corresponding switching device are suppressed.
Charging the spring
energy store with motor
operating mechanism
If the circuit-breaker is equipped with a motor operating mechanism (option), the spring
energy store is charged automatically after applying auxiliary voltage.
Control board for circuit-breaker type 2 (example)
NOTE
If the spring energy store is charged and the auxiliary voltage fails, the operating mechanism
and the interlocks are blocked mechanically.
➭ To deactivate the blocking of the operating mechanism and the interlocks, switch the
auxiliary voltage on again.
