ABSTRACT:
A circuit interrupter with improved current withstand capability characterized by stationary and movable contact means, the stationary contact means comprising first and second conductors being substantially parallel and having an air gap therebetween, the first conductor being pivotally mounted on the second conductor and being in the zone of pivotal movement of the first conductor so that when a fault current of predetermined conditions occurs a magnetic flux between the first and second conductors urges the first conductor toward the movable contact means.
