Front mounted rotary operator

The front mounted rotary operator is available in two versions:

Switching position indicator of front mounted rotary operator

Front mounted rotary operator with door interlock

The front mounted rotary operator with door interlock projects through the cubicle door. This arrangement ensures that the molded case circuit breaker can be switched on only when the control cabinet door is closed. The door is locked automatically when the front mounted rotary operator is turned to position ON (I).

Overriding the door interlock

The door interlock can be overridden by a deliberate action. This means that the door can be opened with the operator in position ON (I) so that maintenance can be carried out, for example.
