The LV848542 is an OFF-position locking kit with Kirk adaptation and padlock, designed for Schneider Electric MTZ2 and MTZ3 circuit breakers. It physically secures the breaker handle in the OFF position, preventing unauthorized or accidental re-energization during maintenance or lockout/tagout procedures.
If a form-fit-function replacement is needed, the buyer must evaluate the MTZ2/MTZ3 accessory catalog for current locking options, or source the LV848542 through the secondary market against an RFQ.
The kit mounts directly onto the MTZ2 or MTZ3 circuit breaker mechanism. The Kirk key adaptation allows integration with a facility's existing Kirk-key interlock system, so the breaker cannot be turned ON until the key is released from the lock. The padlock provision adds an additional independent lockout point for multi-worker safety. This is a mechanical accessory, not an electrical component — no wiring, no ratings, no power consumption. The only spec that matters for procurement is the single-unit packaging (1 per kit).
