Locking device VA-752 in the OFF position 3 locks 2 keys DEKraft 27249DEK

When the circuit breaker is in the disconnected position, it can be locked against switching on using a key lock. In this case, the circuit breaker can only be switched on when the lock is opened with the key and the key is not removed from the keyway. There are three variants of this locking method (the last two are used in a two-line distribution system with one connection interface): one lock, one key; two locks, one key; three locks, two keys
