Abstract
A circuit breaker for interrupting the flow of current upon the detection of excess current or temperature is provided that contains an arc plate assembly which includes a pair of insulative mounting plates having mounted thereon a set of arc plates arranged in an arcuate array generally tracing the arcuate path of movement of a circuit breaker moveable contact blade. A baffle plate is mounted between the insulative mounting plates and positioned above the uppermost arc plate in the set of arc plates for blocking arc-formed debris from projection into the operating mechanism of said circuit breaker. Mounting tabs, which are extending toward the insulative mounting plates from edges of the arc plates, are being used to connect the mounting plates with the arc plates by passing the tabs through corresponding apertures located in the mounting plates. The tabs are crimped against the exterior surface of the mounting plates.
