Abstract:
1. A circuit protection device for use with a circuit that includes at least one pair of conductors, said circuit protection device configured to generate an arc, the arc generating arc products including arc gases, said circuit protection device comprising: at least one pair of electrode assemblies, a first electrode assembly of the pair of electrode assemblies electrically coupled to a first conductor of the at least one pair of conductors, and a second electrode assembly of the pair of electrode assemblies electrically coupled to a second conductor of the at least one pair of conductors, said at least one pair of electrode assemblies configured to generate the arc; a conductor base for mounting said electrode assemblies thereon; a cover coupled to said conductor base and defining at least one isolation chamber, wherein said pair of electrode assemblies is disposed within said at least one isolation chamber; a containment shield disposed on said conductor base within the isolation chamber, said containment shield defining a containment chamber enclosing said at least one pair of electrode assemblies, said containment shield configured to at least partially contain arc products within the containment chamber; and a biasing assembly positioned between said cover and said containment shield and coupled to at least one of said cover and said containment shield, said biasing assembly configured to permit said containment shield to move away from said conductor base to thereby define a gap between said conductor base and said containment shield to enable at least some of the arc gases to vent from the containment chamber.
