11 Motor operator (-MAS)
Automatically loads the closing spring of the circuit-
breaker’s operating mechanism. Once the circuit-
breaker has closed, the motor immediately begins
to reload the closing spring.
The closing spring can still be loaded in the manual
mode (using the relative lever built into the
operating mechanism) in a power failure or during
maintenance work.

12 Closing spring loaded/discharged signaling
contacts (-BGS2)
Consists of a microswitch allowing remote signaling
of the state of the closing spring of the circuit-
breaker operating mechanism.
The following settings can be obtained:
• contact open: spring loaded signal
• contact closed: spring discharged signal
The two signals must be used for circuits with the
same energizing voltage
