NZM1-XUHIVL208-240AC Eaton Molded Case Circuit Breaker

The Eaton Moeller NZM1-XUHIVL208-240AC is an undervoltage release accessory designed for NZM1(-4) and N(S)1(-4) molded case circuit breakers. It operates at 208–240V AC (50/60 Hz) and includes two early-make normally open auxiliary contacts plus a prewired 3-meter connection cable. The 208–240V rating identifies the supply voltage range for compatible breaker installations, while operation at 50/60 Hz supports use across those stated frequencies. Designed for load-shedding, interlock, and emergency-stop use, the device prevents unintended contact under undervoltage conditions and offers approximately 20 ms of early engagement during manual switching. It cannot be combined with remote operators (NZM…-XR), early-make modules (XHIV), or shunt releases (XA). The accessory is certified to UL, CSA, IEC, and CE standards.
