Quick Summary

The Eaton transformer relay ETR-5000-2A0KA1 delivers advanced transformer protection for medium-to-large electrical installations. Engineers often grapple with slow fault isolation and limited visibility across complex transformer networks, which can drive unplanned downtime. While the datasheet notes general compliances and recommends confirmation with the manufacturer, verify CE, SIL, and IP ratings with Eaton to ensure regulatory alignment for your site. This device consolidates protection, metering, and diagnostics with eight digital inputs and nine outputs, plus Modbus and DNP3 TCP over LC fiber, IRIG-B Trip Coil Monitor, and URTD interface options. By integrating protection, metering, and diagnostics in a single platform, teams can streamline maintenance planning, shorten mean time to repair, and improve overall system reliability.

Eight digital inputs and nine outputs provide robust I/O capacity for transformer protection logic. This simplifies control schemes, reduces field wiring complexity, and lowers commissioning time. In practical deployments, you can implement zone selective interlocking and synchronized protections in substations and large plants without rewiring cabinets. Wide power-supply range supports 19-300 Vdc and 40-250 Vac, with 50/60 Hz operation. This flexibility lets you reuse existing power systems and lower cabling costs during upgrades. Ideal for retrofit projects or multi-site deployments where supply conditions vary across installations. Powerful communication and monitoring options include Modbus/DNP3 TCP over LC duplex fiber and URTD Interface with IRIG-B Trip Coil Monitor. The business impact is real-time visibility, remote diagnostics, and easier integration with SCADA or historian systems. This is especially valuable in data centers, utilities, and OEMs requiring high reliability and time synchronization. Integrated sensing and protection—differential protection, current protection and metering, power protection and metering, and voltage protection and metering—deliver comprehensive transformer reliability. The result is faster fault detection, better protection coordination, and reduced outage duration across critical feeders and generation steps. Removable terminals and projection mounting facilitate quick installation and straightforward field service. This reduces commissioning time and simplifies maintenance, especially in crowded switchgear assemblies or space-constrained installations. Compatibility with the ETR-4000 base and URTD interface options provides a clear upgrade path and lower total cost of ownership. Direct plug-in upgrades minimize risk when modernizing legacy protection schemes. Warranty terms (one year from installation or 18 months from shipment) offer industry-standard protection and support, while Eaton’s collateral—datasheets and application notes—supports safer deployment.
