ABSTRACT:
The present invention is directed to a protective device that includes a hot line terminal, a neutral line terminal, a hot load terminal, and a neutral load terminal. A low pass filter circuit has a capacitor coupled in series with a solenoid coil of the protective device. The low pass filter is coupled across the hot line terminal and the neutral line terminal. A miswire detection circuit is configured to detect a miswire fault condition when AC power is coupled to the hot load terminal and the neutral load terminal. An interrupting contact assembly includes interrupting contacts that provide electrical continuity between the hot line terminal and the hot load terminal and the neutral line terminal and the neutral load terminal in a reset state. The interrupting contacts are open in a tripped state. An indicator circuit is coupled to the interrupting contact assembly and being configured to indicate the tripped state and/or the reset state.
