NZM1-XUL380-440AC Eaton Molded Case Circuit Breaker

The NZM1-XUL380-440AC is a molded case circuit breaker configured with an undervoltage release. The release is intended for use with a 380-440V AC electrical system and provides undervoltage protection by opening the breaker when the monitored voltage drops below the release’s operating level. Its voltage range makes it applicable to installations operating within 380V AC to 440V AC, including equipment and distribution circuits that require automatic disconnection during an undervoltage condition. The unit retains the molded case circuit breaker format, allowing installation as a molded case circuit breaker while adding undervoltage-release functionality to the protection scheme. Its model designation identifies the undervoltage-release configuration and the 380-440V AC operating range for application matching and specification review.
