ABSTRACT:
A circuit interrupter comprising a stationary contact assembly having a stationary contact element securely attached to a stationary conductor, and a movable contact assembly having a movable contact element secured on a movable contact arm and operable in response to an overcurrent between ON and OFF positions relative to the stationary contact assembly. An arc runner is attached to the stationary conductor by a single rivet and includes an elongated main body extending along the stationary conductor for expanding an electric arc generated between the movable and the stationary contact elements upon current interruption. The circuit interrupter further comprises a pair of tabs mounted to the arc runner for defining a pair of sloped engagement surfaces for receiving and positioning therebetween the stationary conductor when the stationary contact assembly is assembled.
