Eaton UVR125VDC Undervoltage Relay - IEC Rated
Part Number: UVR125VDC
Quick Summary
The UVR125VDC undervoltage relay from Eaton provides reliable DC undervoltage protection for W-VAC panels and control circuits. When the supply sags or fails, it opens the circuit breaker to prevent equipment damage and unplanned downtime. This IEC Rated device is designed to work with both DC and AC sources, and it pairs with W-VACiMB for streamlined control of mission-critical loads. For engineers, the result is consistent protection, fewer nuisance trips, and easier compliance with electrical protection standards. With its compact footprint and straightforward wiring, it supports fast installation, predictable maintenance planning, and a clear path to scalable service in industrial environments.

Type
Undervoltage relay
Voltage rating
110-125 Vdc
DC undervoltage detection within a 110-125 Vdc range protects critical loads before contact wear and fault cascades occur. The business impact is reduced unplanned downtime and longer life for starter motors and relays. In an automation panel, this means fewer trips and more stable process control for lines powered by W-VAC systems. Seamless W-VACiMB compatibility and dual AC/DC operation offer installation flexibility across legacy and new builds. The 8 in L × 6 in W × 3 in H enclosure weighs 3 lb, enabling straightforward panel mounting with minimal space impact. For field wiring, the catalog notes simplify wiring strategies by using direct connections and standard terminals. IEC Rated certification ensures conformity with international electrical protection standards, supporting regulatory compliance and safer maintenance. The device switches a circuit breaker on undervoltage, a precise control strategy especially valuable in critical production lines. The 110-125 Vdc rating makes it ideal for DC control circuits and for automation architectures that require robust protection without sacrificing performance. Reliability and service are supported by a 1-year Eaton warranty, with documented specs and a straightforward procurement path for W-VAC protection. In power distribution for manufacturing and process industries, undervoltage relays like UVR125VDC help meet uptime targets and energy efficiency goals.
