ABSTRACT:
A circuit breaker has contacts which are engageable as a result of manual operation of a toggle mechanism causing the circuit breaker to close and open when the toggle is in an erect and collapsed condition, respectively. Subsequent opening of the circuit breaker is accomplished by either manual operation or automatic due to a current responsive latch within the toggle mechanism. As a result of a unique movable contact biasing arrangement, more uniform pressure is obtained between the contacts and a wiping action of the contacts is obtained during closing. The movable contact is mounted on a contact member pivoted at its center on a solid pin mounted in the breaker case through an elongated aperture in the contact member. The elongated aperture allows for a limited degree of movement of the contact member transverse to the pivot pin. It is this limited transverse movement which increases the tolerance range by providing overtravel of the movable contact and wiping action of the contacts.
