Abstract
A technique is provided for enhancing performance of a circuit interrupter by deionizing arc plasma developed during an interruption event. A source material is disposed in a secondary current carrying path parallel to a primary current carrying path through the device. Upon movement of a movable contact in the primary current carrying path, current begins to flow through the source material, causing surface ablation of a material which deionizes arc plasma, resulting in greater voltage investment in the arc and more rapid extinction.
