Claim Text:
1. A protective device comprising: a housing assembly including a back body member and a front cover portion; a line interface assembly disposed on a first printed circuit board (PCB) in a first plane within the back body member, the first PCB having an interface aperture formed therein, the line interface assembly comprising a dielectric housing including a cylindrical enclosure and an interface portion, a toroidal sensor assembly comprising at least one toroidal sensor being disposed inside the cylindrical enclosure, the first PCB being configured to substantially cover the cylindrical enclosure to complete the cylindrical enclosure when the interface portion is inserted into the interface aperture, the toroidal sensor assembly not being electrically connected to the first PCB, the line interface assembly also including a plurality of line terminals having a hot line terminal portion and a neutral line terminal portion electrically connected to the first PCB, the line interface assembly also including a hot line contact arm and a neutral line contact arm at least one of which is routed through the toroidal sensor assembly, the hot line contact arm and the neutral line contact arm having termination portions configured to mate with the hot line terminal portion and the neutral line terminal portion, respectively, within the interface portion, the plurality of line terminals being coupled to at least one conditioning circuit disposed on the first PCB, the at least one conditioning circuit being configured to condition AC line signals; and an electromechanical circuit assembly disposed on a second (PCB) within the back body member, the second PCB being disposed in a second plane offset from the first plane by a predetermined distance and configured to receive the conditioned AC line signals, the second PCB also including a fault detection portion electrically coupled to the toroidal sensor assembly, the electro-mechanical circuit assembly including a plurality of load terminals, the plurality of load terminals and the plurality of line terminals being electrically coupled in a reset position and decoupled in a tripped position.
