Technical Specifications Parameter Specification / Typical Value Manufacturer / Brand Eaton Model Number NZM2/3-XHIV (This is a base model; full code specifies voltage) Product Line NZM (Accessory for) Device Type Under-Voltage Release (UVR) Compatible Breaker Frame NZM2, NZM3 Mounting Mounts directly onto the compatible NZM breaker Full Ordering Code Example NZM2/3-XHIV400AC (This would specify a 400V AC operating voltage). The voltage must be specified. Typical Operating Voltages Available for common AC voltages (e.g., 230V, 400V, 500V AC). The specific voltage is CRITICAL. Trip Threshold Typically trips when voltage drops to 35% - 70% of its rated operating voltage. Reset Voltage The breaker can typically be reset once the voltage is restored to above approx. 85% of the rated voltage. Power Consumption Continuously consumes a small amount of power when energized. Standards Compliance As part of the breaker assembly, it helps comply with IEC 60947-2.
