Eaton / Westinghouse QNP3050 – 50A 3 Pole Miniature Circuit Breaker Brand New

Maintaining older electrical distribution systems requires exact-fit components like the Eaton QNP3050. This 50-amp, three-pole plug-on breaker provides essential thermal-magnetic protection with a 10kAIC interrupt rating at 240VAC, making it ideal for commercial facilities. It installs into legacy Westinghouse, Quicklag, and Eaton Pow-R-Line panels without modification. For users seeking current-generation equivalents, this legacy model is officially replaced by the QP3050 substitute.
