Quick Summary

Eaton transformer relay protects transformers in electrical plants and substations, delivering reliable protection and precise control for critical assets. Configuring protection logic and remote fault monitoring can be time consuming without a unified, scalable solution that harmonizes inputs, outputs, and alarms. Typical industry certifications include CE marking, SIL ratings, and IP ratings; verify exact scope with Eaton to ensure site-specific compliance. Designed for transformer protection, monitoring, and metering, it suits OEMs, engineering contractors, and utility-scale installations seeking operational certainty. With Modbus TCP over Ethernet and flexible IO configurations, you gain real-time visibility, faster fault isolation, and lower maintenance costs across fleets.

FAQs

Begin with securing the unit using its removable terminals and semi-flush mounting layout. Verify the panel has space for the 8 digital inputs, 9 digital outputs, and both analog channels. Connect the power supply within the 19-300 Vdc and 40-250 Vac range, then wire the Ethernet port for Modbus TCP or DNP3. Finally, align base-relay compatibility with the ETR-4000 and perform a checkout of protection logic using Eaton's configuration tools.
Key specs include power supply range of 19-300 Vdc or 40-250 Vac with 50/60 Hz, 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. The unit also supports Modbus TCP or DNP3 over Ethernet RJ-45, plus optional interfaces like URTD and IRIG-B for time coordination and fault analytics. Current sensing inputs accommodate 5A and 1A ranges as part of measurement capabilities.
Yes. The device is built for transformer protection, monitoring, and metering in utility-scale environments. Its 8/9 IO configuration supports protection schemes, while Modbus TCP or DNP3 integration simplifies SCADA interfacing. The option for Zone Selective Interlocking and Trip Coil Monitor further enhances protective coordination, enabling faster isolation of faulty sections to minimize outages.
The datasheet lists Compliance as 'Contact Manufacturer,' so confirm exact certifications with Eaton for your installation. Industry expectations for transformer protection equipment often include CE marking, SIL ratings, and IP ratings; however, verify the exact scope and any site-specific requirements directly with Eaton prior to procurement and installation.
Maintenance benefits come from modular IO, removable terminals, and base-relay compatibility with the ETR-4000, which simplify upgrades and field diagnostics. The integrated Modbus TCP/DNP3 interface enables remote monitoring and fault analytics, reducing on-site visits. Over time, this leads to lower maintenance costs, improved uptime, and a faster return on investment through optimized protection coordination.
