The Westinghouse NB2800PRF is a 2-pole molded case circuit breaker frame from the Tri-Pac family, designed to provide overcurrent protection through a thermal magnetic mechanism with LI (Long-Time and Instantaneous) trip functions. It is rated for 600V AC, 800A continuous current, and offers an interrupting capacity of 30kA at 480V, suitable for single-phase industrial applications. This bolt-on unit weighs 61 lb and is supplied as a frame only, meaning it does not include lugs or a trip unit, requiring separate selection for full functionality. The breaker complies with industry standards for molded case circuit breakers and is typically used in distribution panels and switchboards for heavy-duty load management.
