DESCRIBE

The Eaton NZM2/3-XUHIV380-440AC is an Under-Voltage Release (UVR) accessory module designed for the NZM2 and NZM3 frame sizes of Eaton's NZM series molded case circuit breakers (MCCBs). This device continuously monitors the line voltage. If the voltage drops below a specified threshold (typically between 0.35 and 0.7 times the rated voltage) or fails completely, it will automatically trip (open) the circuit breaker it is attached to. This function protects connected equipment from operating at undervoltage conditions, which can be harmful to motors and other electrical devices.
