Westinghouse 373D958G16 Current Limit-R Standard Mechanism Circuit Breakers

Description:

The Westinghouse 373D958G16 Vari-Depth Mechanism is a breaker operating mechanism designed for use with Westinghouse Current Limit-R circuit breakers and disconnect switch assemblies. It provides external manual operation of the breaker through an enclosure door while accommodating varying enclosure depths through an adjustable shaft and linkage arrangement. This mechanism allows operators to safely switch the breaker ON and OFF without opening the enclosure, making it ideal for industrial switchgear, motor control centers, and power distribution equipment. Vari-depth mechanisms are specifically designed for deep enclosures and are commonly used in NEMA-rated electrical cabinets.

Applications:

The Westinghouse 373D958G16 vari-depth mechanism is commonly used in industrial switchgear, power distribution panels, motor control centers, manufacturing facilities, utility power systems, and OEM electrical equipment where Current Limit-R breakers require external operation through a door-mounted handle mechanism while maintaining personnel safety and enclosure integrity.
