NZM2/3-XUHIV220-250DC Eaton Molded Case Circuit Breaker

The Eaton Moeller NZM2/3-XUHIV220-250DC is a specialized accessory designed for NZM2 and NZM3 molded case circuit breakers, providing critical undervoltage release functionality within a 220–250VDC operating range. It features two early-make normally open (N/O) auxiliary contacts, which activate approximately 20 milliseconds before the main contacts during manual switching. This design prevents unintended closure when voltage is insufficient, enhancing safety and reliability in interlock, load-shedding, and emergency-stop applications. The device utilizes screw terminals for secure connections and complies with UL, CSA, and IEC standards, making it suitable for global use where dependable undervoltage protection is required. However, it is not compatible with NZM...-XR remote operators, NZM...-XHIV early-make contacts, or NZM...-XA shunt releases.
