ABSTRACT:
A circuit breaker including a stationary contact and a plurality of movable contacts operable between open and closed positions with respect to the stationary contact. A contact carrier engages the movable contacts, and holds them such that the movable contacts operate together between the open and closed positions. A crossbar and spring holder is secured to the contact carrier and has an aperture therethrough through which is disposed a cross arm. The cross arm extends outwardly from the crossbar and spring holder, and moves upon movement of the crossbar and spring holder, the contact carrier and the movable contacts. Also included is an operating mechanism engaging the cross arm for effecting relative movement of the cross arm to move the movable contacts between the open and closed positions.
