ABSTRACT:
The present invention is directed to a protective device that includes a plurality of line terminals, a plurality of load terminals, and a fault detection assembly coupled to the plurality of line terminals. The fault detection circuit is configured to provide a fault detection output in response to detecting a fault condition. A circuit interrupter is coupled between the plurality of line terminals and the plurality of load terminals. The circuit interrupter includes a first set of contacts, the first set of contacts being configured to close to establish at least one electrically continuous path between the plurality of line terminals and the plurality of load terminals in a reset state. The first set of contacts are also configured to open to disconnect the at least one electrically continuous path in response to the fault detection output to enter a tripped state. An auxiliary switch is coupled to the fault detection assembly. The auxiliary switch includes a second set of contacts configured to decouple at least a portion of the fault detection assembly from a source of electrical power in the tripped state. A latch assembly is coupled to the circuit interrupter. The latch assembly includes a first latch block mechanism configured to close the first set of contacts in the reset state and a second latch block mechanism configured to open the second set of contacts in the tripped state.
