ABSTRACT:
A narrow molded case circuit breaker is constructed with a planar cradle having an edge portion to achieve relatching and another edge portion to achieve kicking of the contact arm for weld breaking. A single bonding operation is utilized to connect the movable contact directly to a flexible conductor and at the same time simultaneously secures the movable contact and conductor to the movable contact arm. Since the movable contact is bonded directly to the flexible conductor, the movable contact arm may be constructed of steel or other relatively poor electrical conducting material.
