Abstract
An arc-fault detecting circuit-breaker system is 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 includes a normally closed circuit breaker, an arc-fault detector of the occurrence of an arc fault in the protected electrical circuit, and a circuit-breaker activating element operable responsive to the detector. The circuit-breaker activating element opens the circuit breaker in the event that the detector detects an arc fault in the protected electrical circuit. A status indicator structure, preferably in the form of a two-part pop-up button, has a first status indicator element which indicates the opening of the circuit breaker due to the overcurrent fault, and a second status indicator element which indicates the opening of the circuit breaker due to the arc fault.
