ABSTRACT:
A stationary contact assembly is provided for a circuit breaker which has a base, a line terminal and an arc chute. The stationary contact arm is J-shaped and formed from a single piece of conductive material which has a contact affixed to the short leg of the J and is connected to the line terminal. The short leg of the J has a length sufficient for creating electromagnetic blow open forces in response to current flow of a preselected magnitude. An arc runner is positioned between the legs of the J for drawing out an arc into the arc chute and intensifying the electromagnetic repulsion forces.
