摘要:
An arc extinguishing contact assembly for a circuit breaker assembly is provided. The arc extinguishing contact assembly includes a fixed contact assembly, a movable contact assembly and an arc extinguishing assembly. The fixed contact assembly includes a fixed arc contact assembly, a fixed main contact assembly, and a number of movable, intermediate arc contact assemblies. The movable contact assembly includes a movable arc contact assembly and a movable main contact assembly. The arc extinguishing assembly is structured to extinguish an arc generated as the movable contact assembly moves between an open, first position and a closed, second position.
