Abstract:
1. A circuit breaker comprising: a base; a stationary contact; a plug-on half jaw mounted to the base and having a contact end on which the stationary contact is mechanically and electrically secured; the half jaw having only a single terminal end that is generally perpendicular to the contact end; and a jaw spring mounted to the base and operatively coupled to the half jaw, the jaw spring having a bridge portion connecting two symmetrical spring legs including a first spring leg and a second spring leg, the bridge portion being located between the base and the single terminal end when the half jaw and the jaw spring are mounted to the base, the jaw spring having a flat surface in which the width is larger than the thickness, the jaw spring including two angled receiving surfaces positioned respectively at an end of one of the spring legs, the receiving surfaces being symmetrically angled with respect to a central symmetry line of the jaw spring such that both receiving surfaces are in the same plane with both spring legs and the central symmetry line; wherein the first spring leg is positioned in an overlapping position over the single terminal end, the second spring leg being positioned opposite the single terminal end such that a receiving gap is formed for receiving only an electrically conductive end of a bus bar in direct contact with the single terminal end and the second spring leg, the bus bar being mounted external to the circuit breaker.
