Locking device to prevent movement of the withdrawable circuit breaker with cylinder locks
With the cylinder locks on the guide frame, the circuit breaker is secured against racking in
the guide frame. The positions CONNECT, TEST, and DISCONNECT can be locked and the
circuit breaker can then no longer be racked in or out.
If multiple guide frames are equipped with cylinder locks, Ronis locks with different lock
numbers are used. This means each guide frame has its own key.
