NZMN3-SE220-CNA Eaton Molded Case Circuit Breaker

The NZMN3-SE220-CNA is an Eaton Series NZM motor protection circuit breaker housed in the NZM3-frame. This molded case device has a three-pole configuration, a 220A current rating, and a 690 Vac voltage rating. The trip unit is magnetic only, providing motor protection without overload release. Its interrupting capacity is 50 kAIC at 415 Vac and 42 kAIC at 480 Vac; these kAIC values state the available fault-current interruption ratings at the corresponding voltages. A rocker lever forms the operating interface, and the unit includes a motor drive. Front screw connection is specified for installation. Together, the NZM3 frame, three-pole arrangement, 220A rating, 690 Vac rating, magnetic-only trip, and kAIC values define the breaker’s core electrical and protection characteristics.
