Eaton IZMX-UVR48DC-1 Undervoltage Release - UL Listed
Part Number: IZMX-UVR48DC-1
Quick Summary
The Eaton IZMX-UVR48DC-1 undervoltage release protects motor circuits by monitoring 24-48 Vdc and triggering the release when undervoltage is detected. This helps prevent unexpected restarts and equipment damage in motor control centers. UL Listed certification confirms safety compliance for industrial environments, while its universal NRX frame compatibility ensures easy retrofits across multiple starter configurations. The unit is designed as a 48 Vdc UVR Assy Kit – PXR, matching the Power Defense ICCB line to streamline installation. With compact dimensions and a standard 8.75 in depth, it integrates into existing panels with minimal wiring changes, delivering reliability, reduced maintenance, and improved uptime for critical processes.
