The Westinghouse HFB3050V is a three-pole molded case circuit breaker from the MARK 75 family, designed for overcurrent protection in industrial power distribution systems. It is rated for 50A continuous current at 600VAC, with an interrupting capacity of 25kA at 480V, and utilizes a thermal-magnetic trip mechanism for LI (Long-Time and Instantaneous) protection. The unit features a bolt-on connection, weighs 11 lb, and is constructed for three-phase applications. It complies with applicable UL and NEMA standards for molded case circuit breakers. Typical applications include motor control centers, panelboards, and switchboards in commercial and industrial facilities.
