More Information
Summary:A handle arm assembly is for a circuit interrupter including an undervoltage release mechanism having a reset mechanism. The handle arm assembly includes a body portion rotatable through an arc between an on position, an off position, and a reset position beyond the off position and an arm portion projecting laterally from the body portion out of the plane of the arc through which the body portion rotates. The body portion and the arm portion are formed from a single piece of material wherein the body portion and the arm portion are different portions of the single piece of material. The arm portion is structured to engage the reset mechanism in a manner such that arcuate movement of the arm portion as the body portion moves to the off position is translated into actuation of the reset mechanism.
