ABSTRACT:
An arc chute for assisting in the extinction of an arc drawn between circuit interrupting contacts opening in air includes a stack of closely spaced metallic plates coated with a weld deterent material, such as silicone varnish. By virtue of this coating, the propensity of metal particles condensed from the metal vapor generated by the arc to weld to the arc plate surfaces is reduced. Consequently, material degradation of the arc chute dielectric strength is avoided, and arc reignition is discouraged.
