Patent ID: 7436639

Claim:
A module having a relay and transformer connectable to a printed circuit board (PCB) in a ground fault circuit interrupter (GFCI), the module comprising: a first transformer having a core and electrically coupled to a first set of terminals for connection to a printed circuit board (PCB); a second transformer magnetically coupled to said first transformer is electrically coupled to a second set of terminal for connection to said PCB; a double pole single throw (DPST) relay having a pair of stationary contacts, a pair of movable contacts and an electrical coil surrounding a magnetic core; and a structural support for mounting said first transformer, said second transformer, and said relay independent of the printed circuit board and in fixed relative position; wherein a radial axis of each of said first transformer, said second transformer and said relay are substantially parallel with respect to each other, and wherein at least one cross-section of one of said first and said second transformers taken along a plane perpendicular to said radial axes of said first and second transformers is coplanar with at least one cross-section of said relay taken along a plane perpendicular to said radial axis of said relay.
