The LA1CL is a circuit breaker cylinder lock — a mechanical accessory that secures the operating handle of a panel-mounted circuit breaker in the OFF position, preventing unauthorized or accidental re-energization during maintenance.
The LA1CL is obsolete.
This cylinder lock is designed for use with specific Schneider Electric circuit breaker families. It replaces the standard handle mechanism with a key-lockable version, adding a physical lockout point for compliance with lockout/tagout (LOTO) procedures on the panel door.
