Locking capability of mutually interlocking 3VL circuit breakers
Can the 3VL circuit breakers be locked in the OFF position?
Are additional components required for this?
Cable locking cannot be used to lock 3VL circuit breakers.
They can only be locked when used with front rotary operating mechanisms or motor drives.
The circuit breakers can be locked in the OFF position with the rear interlocks with rocker (3VL9600-8LC0 and 3VL9600-8LD00).
The locking mechanisms for toggle handles, padlocks or a security lock can be used for this when using front rotary operating mechanisms and motor drives.
