DESCRIBE

The Eaton NZMS1-A125 is a 125-ampere, 3-pole, Molded Case Circuit Breaker (MCCB) from the industrial-grade NZM series. This model belongs to the compact NZMS1 frame size, designed for high performance in a relatively small footprint. It is typically a fixed-mount breaker equipped with a fixed thermal-magnetic trip unit. This type of trip unit provides robust, maintenance-free protection against overloads (using a bi-metallic strip) and short-circuits (using an electromagnetic solenoid).
