Eaton NSB FAZ-B15 2-NA Miniature Circuit Breaker

The Eaton NSB FAZ-B15 2-NA Miniature Circuit Breaker is a two-pole overcurrent protection device in the Eaton NSB family, rated for 15 A and intended for 480 V systems operating at 50 or 60 Hz. It trips automatically when the current exceeds its 15 A rating due to overloads or short circuits, protecting wiring insulation and connected equipment in electrical distribution panels. The two-pole construction disconnects both live conductors, providing safe isolation of the circuit during maintenance or fault conditions and helping to prevent arc faults in 480 V installations. The FAZ-B15 2-NA designation identifies the specific model and protection level within Eaton’s FAZ-series MCBs, making it suitable for inclusion in industrial or commercial panels that require two-pole protection with a 15 A rating at 480 V.
