Device for signaling the triggering of a circuit breaker

摘要

A circuit breaker comprises a lock (12) having a high position when the circuit breaker is triggered and a low position when the circuit breaker is set. The lock in the low position is held by a locking lever (10) against which the lock abuts. The lever cooperates with a device for detecting a current surge which, during a surge, disengages the lever so that the lock no longer abuts against the lever and is released in order to go back to its high position. The locking lever is movable between a high position and a low position, urged to its low position when the lock is set to low position, and associated with upward biasing means active (50) when the lock no longer abuts against the lever.
