In the test/disconnected position, the withdrawable part is still completely inside the panel with the door
closed. The ON/OFF pushbutton located on the circuit-breaker, and the mechanical indicators for ON/
OFF and CHARGED/DISCHARGED can be observed through an inspection window if the circuit
breaker is in service position.
The switching operations are carried out with the doors closed. Installation of an additional mechanical
switching device for manual operation of the circuit-breaker in the service position is also possible (see
fig. 7, 8).
The socket 10.1 (figure 4) for the control wiring is mounted fixed in the circuit-breaker compartment.
