The 3VA molded case circuit breaker can also be locked in the OFF (O) or ON (I) position by

against further operation once it has been locked.

cylinder lock is installed in an accessory compartment of the 3VA molded case circuit
breaker.

Selection of the lock number is highly flexible, i.e. it can be selected from a choice of
three different lock numbers. If different cylinder lock numbers are required for multiple
locks, they can be selected from the predefined article numbers stated in the catalog.
