Westinghouse CMC225KA Operating Mechanism for MC Breaker

The Westinghouse CMC225KA operating mechanism provides reliable mechanical breaker operation and switching control for industrial circuit breaker control systems. Designed for panel-mounted installation in switchgear and MCC panels, it supports JA, KA, HKA, LB, and HLB breaker configurations and uses a NEMA 12 enclosure for industrial environments. Its primary function is precise mechanical breaker operation and switching control within power distribution and electrical control systems, making it suitable for manufacturing facilities, electrical substations, and heavy-duty distribution equipment when paired with compatible Westinghouse breaker assemblies. Common replacements include Eaton CMC225KA Breaker Operating Mechanism; Westinghouse KA Series Breaker Mechanism Assembly; and Cutler-Hammer CMC225KA Operating Mechanism.
