Closing coil (CC) / shunt release (ST)
With the auxiliary solenoids (CC and ST), the circuit breaker can be closed and opened
remotely by electrical signals connected at the auxiliary conductor terminal system or via
communication.
Closing (breaker position CLOSED) is only possible if the closing springs are charged and
the circuit breaker is ready for closing. Opening (breaker position OPEN) is always possible.
The coils work with a current pulse ≥ 100 ms or with constant power input (100
% ON time
in %).
Note
If the opening command was issued with a shunt release, the circuit breaker can be reclosed
with a closing command after the shunt release has been switched off followed by a wait
time ≥ 30 ms.
The opening command always has priority over the closing signal.
