Eaton NZM1-XUHIV380-440AC Undervoltage Release is an undervoltage protection accessory for the NZM1 series molded-case circuit breakers. It uses a 380–440 VAC coil to trip the breaker when supply voltage falls outside the set range, safeguarding control circuits and connected equipment from undervoltage conditions. Designed for use with the NZM1 family, this UVR provides reliable voltage monitoring in electrical panels and motor control applications that depend on stable power.
