ABSTRACT:
In a ground fault circuit interrupter (GFCI), a pair of flexure arms having moveable contacts disposed thereon are deflected in response to the activation of a solenoid having a moveable core. The core of the solenoid causes a pair of cam actuators which are preferably coupled together by a catcher to rotate. The rotation of the cam actuators causes the deflection of the flexure arms, thereby separating the moveable contacts from the stationary contacts and interrupting the flow of current. The activation of the solenoid is controlled by an electronic module. The electromechanical current interrupter and the electronic module are disposed within a housing that can be mounted within a standard electrical receptacle box.
