ABSTRACT:
The present invention is directed to a protective device that includes a plurality of line terminals and a plurality of load terminals. A fault detection circuit is coupled to the plurality of line terminals. The fault detection circuit is configured to provide a detection output signal in response to a detected condition. A switching device is coupled to the fault detection circuit. The switching device is configured to provide a trip signal in response to the detection output signal, the switching device being characterized by at least one device parameter. A circuit interrupting assembly is configured to electrically connect the plurality of line terminals and the plurality of load terminals in a reset state and disconnect the plurality of line terminals from the plurality of load terminals in response to the trip signal in a tripped state. An indicator circuit assembly is coupled to the switching device. The indicator circuit assembly is configured to generate a user-perceivable output signal based on the at least one device parameter.
