Abstract
A circuit breaker has first and second spaced-apart stationary contacts, a plurality of movable contacts and an arcing contact which are capable of operating between open and closed positions. An arc chamber is disposed adjacent one of the stationary contacts, the arcing contact, and the movable contacts, and comprises a frame with back and two parallel sides. A plurality of deionization plates are supported by the frame, and each deionization plate has an opening therein distant from the back of the frame. The deionization plate openings are aligned with each other, and the arcing contact is disposed within the aligned openings. A generally U-shaped arc runner is secured to one of the end deionization plates and one of the stationary contacts. An insulating member is disposed between the arc runner and the stationary contact so that the arc runner is electrically insulated from the stationary contact except where it is secured thereto. Also included is an operating mechanism for effecting movement of the movable and arcing contacts between the open and closed positions.
