An electrical wiring device having a solid-state switch element positioned between the fault detection switch element and the solenoid coil to prevent the solenoid coil from being energized when the circuit interrupter is in the tripped state. The solid-state switch element may have a gate that receives a gate signal that turns the solid-state switch element on when the circuit interrupter is in the reset state and does not receive the gate signal so that the second switch element is turned off when the circuit interrupter is in the tripped state. The gate may be connected to the line terminals and to ground by a mechanical switch responsive to the circuit interrupter state or by another solid-state switch driven by a processor that is programmed to detect whether the circuit interrupter is in the reset state or the tripped state.
