ABSTRACT:
The present invention is directed to a protective device that includes a plurality of line terminals and a plurality of load terminals, the plurality of load terminals including a plurality of hot load terminals and a plurality of neutral load terminals. The device also includes a circuit interrupter having four sets of moveable contacts, the four sets of moveable contacts being configured to couple the plurality of line terminal to the plurality of load terminals in a reset state and to decouple the plurality of line terminals from the plurality of load terminals in a tripped state. A test circuit includes an end of life detection circuit coupled to the plurality of line terminals or the plurality of load terminals by a switch mechanism associated with the four sets of moveable contacts. The test circuit includes a manually actuatable button and a fusible element, the fusible element assuming a permanently open state if the circuit interrupter does not enter the tripped state within a predetermined period after the manually actuatable button has been actuated.
