Feature → Business Impact → Application: The UVR24VDC offers a 24 V DC voltage rating, enabling direct compatibility with common low-voltage DC control networks, reducing wiring complexity and improving response accuracy when power falters. This translates to faster isolation of faulty loads and minimized system-wide downtime in panel assemblies that rely on DC control logic. Application: Ideal for W-VACiMB integrations where compact protection devices are required in dense DIN-rail environments, delivering predictable behavior across direct and alternating current systems. Feature → Business Impact → Application: IEC Rated certification provides proven compliance with essential electrical standards, boosting regulator acceptance and simplifying procurement for regulated facilities. Application: Suitable for safety-critical machinery where reliable undervoltage protection upholds performance metrics and uptime. Feature → Business Impact → Application: 8 in length × 6 in width × 3 in height and 3 lb weight enable easier cabinet fitment and installation, reducing cabinet space and mounting time. Application: Retrofit projects and new builds in control panels where space is at a premium. Feature → Business Impact → Application: Compatibility with W-VACiMB ensures smooth integration with Eaton protection schemes, limiting wiring changes and accelerating commissioning. Application: Automation lines requiring coordinated protection with existing W-VAC components. Feature → Business Impact → Application: Both DC and AC operation capability addresses a wide range of industrial topologies, supporting cross-functional use across motor control centers and the broader plant network. Application: Mixed-voltage environments where a single undervoltage relay can replace multiple devices for cost and complexity reduction.

FAQs
The UVR24VDC is designed for straightforward DIN-rail mounting and direct wiring to W-VACiMB circuits. Verify 24 V DC supply integrity, confirm proper polarity, and ensure the device is correctly positioned to sense control supply dips. Follow Eaton’s catalog notes for wiring diagrams and safety considerations to minimize commissioning time and ensure reliable operation.
Key specifications include a 24 V DC voltage rating, IEC Rated certification, catalog number UVR24VDC, 8 in length, 6 in width, 3 in height, and a weight of 3 lb. It is compatible with DC and AC systems and is used with W-VACiMB to protect loads from undervoltage conditions.
Yes. The device is designed to operate with both direct and alternating current and is intended for DC control circuits. Its 24 V DC rating and IEC rated certification support reliable protection in mixed-voltage environments commonly found in industrial automation and panel design.
The product inherits Eaton’s standard warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. For ongoing support, consult Eaton’s customer service and refer to the catalog notes for installation and compatibility guidance.
Check the 24 V DC supply stability and load wiring for any loose connections. Confirm proper integration with W-VACiMB and verify that DC control circuits are not inadvertently loading the relay. If trips persist, review voltage sag thresholds and consult Eaton’s datasheet for timing and response characteristics.
