Abstract
A handle actuator is provided for a circuit interrupter that has a handle or toggle pivotally movable between operative positions. The handle actuator has a pair of pins that fit tightly on the handle, a pair of retainers coupling the pins in a rigidly spaced parallel relationship, and a pair of flanges fixed to the circuit interrupter via a base. The flanges are disposed on opposite sides of the handle and have arcuate slots that guide the pins coaxially with the pivot axis of the handle. The ends of the pins extend through the arcuate openings of the flanges and are received in the retainers. Connecting links pivotally couple the pins with a drive input for selectively driving the pins against the handle to move the handle between the operative positions. The relative position of the pins on both sides of the handle is constant, preventing wear on the handle due to rolling of the pins against the handle, impacts with the handle permitted by lost motion, or bending and twisting forces.
