Eaton / Moeller Series
500A, 3P, Electronic Trip, UL/CSA/IEC/CE
The Eaton NZMH3-VEF500-NA (Catalog No. 269321) is a 500A, 3-pole molded case circuit breaker with electronic trip technology, designed for branch, feeder, selectivity, and generator protection. Built on the NZM3 frame, it features fixed overload protection (Ir = 500A) and adjustable short-circuit releases, including delayed and instantaneous ranges (750–4000A). It provides high breaking capacities up to 150kA at 400/415V and 100kA at 480V, ensuring robust performance in demanding low-voltage installations. The breaker uses screw terminals, supports rocker lever operation and optional motor drive, and is certified to UL, CSA, IEC, and CE standards for global applications.
