FAQs

Start with mechanical mounting using the Projection method and connect the removable terminals for clean, service-friendly wiring. The unit provides 8 digital inputs and 9 outputs, plus 2 current sensing inputs; plan wiring to minimize loop area. Use URTD interface and IRIG-B options as required, and ensure the power supply is within 19-300 VDC or 40-250 VAC to avoid startup issues.
The relay supports Ethernet-based protocols including 61850, M-Bus TCP, and DNP3 TCP/UDP over RJ45. This enables seamless integration with SCADA and protection schemes, reduces engineering time, and provides standardized data models for fault analysis and transformer health monitoring across heterogeneous networks.
Yes. Designed as a transformer protection relay, it offers current protection and metering capabilities along with differential protection options. With 2 current sensing inputs and 8 DI/9 DO, it supports accurate fault detection, metering data capture, and reliable annunciation, making it well-suited for modern transformer protection applications.
The product lists Compliances as Contact Manufacturer, so formal CE, SIL, or IP ratings should be confirmed with Eaton for your specific region. For regulated environments, request certification documentation and a formal declaration of conformity from Eaton prior to installation to ensure compliance with local standards.
Warranty follows Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on the removable terminals for serviceability, the conformal-coated circuit boards for rugged environments, and the URTD/IRIG-B options to support timing and remote monitoring, which collectively help reduce maintenance overhead and extend mean time between failures.
