A mid terminal for a double break circuit breaker comprises first and second elongated conductive plates, where each of the plates have first and second ends. The second end of the first plate is longitudinally spaced from the first end of the second plate and the first end of the first plate is connected to the second end of the second plate by a lateral conductive plate. A first are runner is electron beam welded to the second end of the first plate, and a second are runner is electron beam welded to the first end of the second plate. The first and second arc runners are preferably made of steel. A first stationary contact is mounted on the first plate adjacent the first arc runner, and a second stationary contact is mounted on the second plate adjacent the second arc runner. To manufacture the mid terminal, the first and second plates and the lateral plate are formed from a single strip of copper bent into a shape having a pair of longitudinal sections extending in opposite directions from opposing ends of a lateral section. The longitudinal sections correspond to the first and second plates, and the lateral section corresponds to the lateral plate.
