Westinghouse 371D957G66 is a JA Series molded case circuit breaker designed for instantaneous magnetic-only protection in industrial power distribution systems. This 2-pole, 1-phase unit is rated for 225A continuous current at 600VAC with an interrupting capacity of 22kA at 480VAC, utilizing a bolt-on connection for secure panel mounting. The breaker weighs 17 lb and features a compact molded case construction with instantaneous trip function for rapid overcurrent response. It complies with applicable industry standards for molded case circuit breakers and is suitable for use in switchboards, panelboards, and motor control centers requiring high-amperage magnetic-only protection. Typical applications include feeder circuits, main disconnects, and branch circuit protection in commercial and industrial facilities where thermal protection is not required.
