Overview
The Eaton FAZ-C30/3-NA is a three-phase, 30-ampere miniature circuit breaker (MCB) designed for branch circuit protection in industrial control cabinets and automation systems. This UL489-listed device features a C-curve trip characteristic optimized for medium inrush currents typical of pilot devices, control solenoids, and small motors. With screw terminals and DIN rail mounting, it integrates seamlessly into modern industrial panels.
