NZM1-XUHIV20LK24DC Eaton Molded Case Circuit Breaker

The Eaton Moeller NZM1-XUHIV20LK24DC is a DC-rated undervoltage release accessory designed for NZM1(-4) and N(N/O)1(-4) molded case circuit breakers. Operating from 24VDC, the unit incorporates two early-make N/O auxiliary contacts that support interlocking, load-shedding, and emergency-stop circuits. These contacts engage approximately 20ms before the main contacts operate, supporting control reliability where early signaling is required. The release functions as a DC-rated accessory for use with the specified molded case circuit breaker families and their control circuits. Installation is modular, allowing straightforward integration with the specified breaker families. The accessory is intended for manual operation only and must not be used with NZM...-XR remote operators or alongside XHIV or XA modules.
