Abstract
The present invention is directed to a protective device that includes a detection circuit, a fault detection circuit, and a circuit interrupter assembly contacts configured to be driven into a tripped state in response to the trip actuation and driven into a reset state in response to a reset actuation. A reset mechanism is configured to provide the reset actuation in response to a user reset input. A test assembly includes a test circuit configured to generate a simulated electrical perturbation exceeding the predetermined level in response to a user test input and a test timing mechanism configured to drive the circuit interrupter into the tripped state and disable the reset mechanism if any one of the detection circuit, fault detection circuit, actuation assembly, or circuit interrupter assembly fail before a predetermined time elapses such that the device is permanently inoperable.
