NZM1-XUHIV20L380-440AC Eaton Molded Case Circuit Breaker

The NZM1-XUHIV20L380-440AC is a molded case circuit breaker component identified as an undervoltage release. Its function is tied to detecting an undervoltage condition within the associated breaker application, where such a release is used to disconnect the circuit when supplied voltage falls below the applicable operating level. The designation 380-440AC is retained as part of the full model number for precise identification, compatibility, and ordering reference. Because it is classified specifically as an undervoltage release, specification matching should focus on the exact model identifier and the molded case circuit breaker application. The 380-440AC portion represents the stated voltage designation within the model code.
