Abstract
A compact module with a pair of transformers and a double pole single throw relay (DPST) mounted onto a housing to create a self contained assembly for installation in a ground fault circuit interrupter (GFCI) as a unit. The first transformer has a core and is electrically coupled to a first set of terminals for connection to a printed circuit board (PCB). The second transformer is located adjacent to and magnetically coupled to the core of the first transformer and is electrically coupled to a second set of terminals for connection to the PCB. The DPST relay has a pair of stationary contacts and a pair of movable contacts for selectively connecting line phase and neutral conductive paths to a load.
