Abstract
A resettable circuit interrupter for ALCI and GFCI applications utilizes movable contacts mounted on contact spring arms adjacent a U-shaped bight of the spring arm. Closing of the contacts is achieved by compression of the bight by an actuating member that is latched in the closed contact position. Unlatching of the actuating member results when current imbalances are detected, so that the contacts are opened by the bias forces produced by the contact spring arms. A reset button is located in a recess between the prongs of the plug-in member so that the device can be reset only when it is unplugged from an electrical receptacle.
