Accessory variant: Locking device
For use with: 3VA1 100/160
Series: 3VA

Locking latches 3VA from Siemens. The available locking latches enable the implementation of a mutual locking mechanism between at least two 3VA molded case circuit breakers. The locking device only allows one of the 3VA molded case circuit breakers to be released at a time; this ensures that only the released overload circuit breaker can be operated. All other 3VA molded case circuit breakers remain in the secured off position (O) and are blocked by the locking mechanism.
