Abstract:
1. An arc-fault detecting circuit-breaker system used in conjunction with a protected electrical circuit whose current flow is to be interrupted upon the occurrence of an overcurrent fault or an arc fault, the arc-fault detecting circuit breaker system comprising: a normally closed circuit breaker electrically connected to the protected electrical circuit, wherein the circuit breaker comprises a movable element that moves between a first position when the circuit breaker is closed and a second position when the circuit breaker is open; an arc-fault detector of the occurrence of an arc fault in the protected electrical circuit; a circuit-breaker activating element operable responsive to the detector, wherein the circuit-breaker activating element creates an overcurrent fault and opens the circuit breaker, in the event that the detector detects an arc fault in the protected electrical circuit; and a status indicator structure comprising:
