Opening and closing via remote access
Remote access is possible in two ways:
● Via the communication system, the precondition being a COM connection and the
COM actuator module
● Via direct electrical signals at the auxiliary conductor terminal system
The circuit breaker can be closed and opened by remote access. For this purpose, the
optional closing coils (CC) / shunt releases (ST) must be installed. You will find information
on these coils in Section Accessories for circuit breaker (Page 75).
Closing/opening the circuit breaker via the communication system
1. Charge the storage spring if it is not already charged.
It is advisable to use the accessory spring charging motor (MO) so that the spring energy
store can be charged via the communication system, too.
2. Transmit a closing/opening command via the COM connection and control system.
Closing/opening the circuit breaker via the auxiliary conductor terminal system
