Description
Delivering high-performance UL 489 branch circuit protection, this 1A, two-pole miniature breaker is built for industrial use. It utilizes a K-curve trip to accommodate high inrush currents without nuisance tripping. The unit mounts easily into standard DIN rail panels and System pro M compact enclosures. It functions as a reliable substitute for Eaton FAZ-K1/2-NA and Schneider M9F43201 breakers. Rated for 10kAIC at 480Y/277VAC, it features a real contact position indicator for visual status.Specifications
