Westinghouse NB31200F is a molded case circuit breaker frame designed for providing robust overcurrent protection in three-phase industrial power distribution systems. It features a 1200A current rating and a 600V voltage rating, engineered to interrupt fault currents up to 30kA at 480V AC. The three-pole, bolt-on thermal-magnetic unit is UL Listed and constructed as a frame-only component, meaning it requires the separate addition of lugs and a trip unit for complete functionality. This design ensures compliance with industry standards and facilitates integration into a variety of high-capacity commercial and industrial panelboards and switchgear.
