Eaton UVR48VDC Undervoltage Relay - IEC Rated
Part Number: UVR48VDC
Quick Summary
UVR48VDC undervoltage relay protects 48 Vdc control circuits in industrial protection systems. When a power dip or loss occurs, it can trigger unwanted circuit trips and downtime; this device helps prevent that by opening the circuit breaker on low supply. It carries IEC Rated certification to support reliable performance in industrial environments, and it supports both DC and AC inputs. By combining compact form with W-VACiMB compatibility, it delivers robust protection while helping engineers streamline installation and maintenance in a demanding manufacturing setting.

FAQs
UVR48VDC is designed for integration with Eaton’s W-VACiMB architecture and standard control panels. It offers a compact footprint (8 in L × 5.5 in W × 3 in H) and a weight of 1.2 lb, enabling straightforward mounting in typical electrical cabinets. Use conventional panel wiring practices and ensure secure connections to minimize resistance and aging. Always consult the latest Eaton datasheet for terminal specifications and wiring diagrams.
The UVR48VDC is rated for 48 Vdc operation and is capable of functioning with both direct current and alternating current inputs in practical applications. This dual compatibility supports flexible integration into mixed power architectures commonly found in industrial control circuits and protection schemes.
Yes. The UVR48VDC is specifically designed as an undervoltage protection relay for 48 Vdc control circuits and is intended for use within W-VAC protection setups. Its function is to open the circuit breaker if the 48 Vdc supply lowers or is lost, thereby safeguarding downstream equipment and maintaining system integrity.
The UVR48VDC carries IEC Rated certification, indicating compliance with IEC-based electrical safety and performance standards. While additional certifications (such as SIL, CE, or IP ratings) are not listed in the provided data, IEC Rated status provides a clear baseline for industrial reliability and safety expectations in centralized protection arrangements.
By preventing nuisance trips caused by voltage dips, UVR48VDC helps reduce unplanned downtime and wear on breakers, translating to lower maintenance costs and longer component life. The device also benefits from a defined warranty window (one year from installation or eighteen months from shipment), improving total cost of ownership and budgeting for replacements or service.
