WESTINGHOUSE 314C359G01 Arc Chute for Type KM Circuit Breaker

Description:

The Westinghouse 314C359G01 Arc Chute is a circuit breaker arc-extinguishing component designed for use with Westinghouse Type KM circuit breakers. It is used to contain, divide, cool, and extinguish the electrical arc generated when breaker contacts open under load or fault conditions, helping protect internal contacts and ensuring safe interruption of electrical current. Commonly installed in industrial switchgear, power distribution equipment, motor control centers, and heavy-duty electrical protection systems, this arc chute serves as a critical replacement component for maintaining the performance and safety of legacy Westinghouse Type KM circuit breakers.

Applications:

The Westinghouse 314C359G01 arc chute is commonly used in Type KM power circuit breakers, industrial switchgear assemblies, electrical distribution systems, motor control centers, utility substations, manufacturing facilities, and power generation equipment where reliable arc suppression and circuit interruption are required. Arc chutes help prevent damage to breaker contacts by directing and extinguishing arcs during switching and fault-clearing operations.
