Abstract
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.

An arc extinguishing contact assembly for a circuit breaker assembly, the circuit breaker assembly including a housing assembly and an operating mechanism, said housing assembly defining an enclosed space, said operating mechanism structured to be operatively coupled to a movable contact assembly and structured to move the movable contact assembly between an open, first position, wherein the movable contact assembly is effectively spaced from a fixed contact assembly, and a closed, second position, wherein the movable contact assembly is coupled to, and in electrical communication with, the fixed contact assembly, said arc extinguishing contact assembly comprising:
- a fixed contact assembly including an arc contact assembly, a main contact assembly, and a number of movable, intermediate arc contact assemblies;
- a movable contact assembly including an arc contact assembly and a main contact assembly, said movable contact assembly structured to move between an open, first position, wherein the movable contact assembly is effectively spaced from said fixed contact assembly, and a closed, second position, wherein the movable contact assembly is coupled to, and in electrical communication with, said fixed contact assembly, with an arcing position there between, wherein when said movable contact assembly and said fixed contact assembly are in said arcing position, a number of arcs form there between;
- and
- an arc extinguishing assembly structured to extinguish a number of arcs generated as said movable contact assembly moves between said first position and said second position.
A circuit breaker assembly comprising:
- a housing assembly defining an enclosed space;
- a fixed contact assembly including an arc contact assembly, a main contact assembly, and a number of movable, intermediate arc contact assemblies, said fixed contact assembly disposed in said housing assembly enclosed space;
- a movable contact assembly including an arc contact assembly and a main contact assembly, said fixed contact assembly disposed in said housing assembly enclosed space;
- an operating mechanism, said operating mechanism structured to be operatively coupled to said movable contact assembly and structured to move said movable contact assembly between an open, first position, wherein the movable contact assembly is effectively spaced from a fixed contact assembly, and a closed, second position, wherein the movable contact assembly is coupled to, and in electrical communication with, the fixed contact assembly, said arc extinguishing contact assembly comprising:
- said movable contact assembly structured to move between an open, first position, wherein the movable contact assembly is effectively spaced from said fixed contact assembly, and a closed, second position, wherein the movable contact assembly is coupled to, and in electrical communication with, said fixed contact assembly, with an arcing position there between, wherein when said movable contact assembly and said fixed contact assembly are in said arcing position, a number of arcs form there between;
- and
- an arc extinguishing assembly structured to extinguish a number of arcs generated as said movable contact assembly moves between said first position and said second position.
