NZM1-XU208-240AC Eaton Molded Case Circuit Breaker

The Eaton NZM1-XU208-240AC is an undervoltage release accessory intended for use with molded case circuit breakers. Its design is compatible with NZM1 breakers in the NZM Series, covering frame sizes J-K. The release operates from a 208 - 240V AC control supply and trips the connected breaker when supply voltage drops below the configured trip threshold. This undervoltage protection supports installations where automatic disconnection is required during a low-voltage condition. The accessory is suited to commercial buildings, institutional facilities, and infrastructure systems that use compatible NZM1 circuit breakers and require undervoltage trip control.
