Eaton ETR-5000-2B3GA0 Transformer Relay - 50/60 Hz

Flexible I/O and sensing capabilities allow comprehensive protection without adding external hardware, reducing wiring complexity and commissioning time. This translates to shorter project timelines and lower installation risk, especially in retrofit scenarios where space is tight. The Eaton ETR-5000-2B3GA0 is well suited for transformer protection within substations, motor control centers, and industrial plants where reliable diagnostics matter. Networked communication via Modbus RTU or DNP3 RTU over RS-485 enables straightforward integration with existing SCADA and monitoring systems, reducing commissioning time and improving operator visibility across the protection scheme. This supports rapid fault isolation and safer, more reliable plant operation. A wide power supply range of 19–300 Vdc and 40–250 Vac, plus 50/60 Hz compatibility, minimizes spare-part inventory and simplifies deployment across global sites, delivering lower total cost of ownership. Sensing and protection capabilities cover differential, voltage, current, and power protection with metering, giving engineers a single, scalable device for both protection and metering. This reduces the need for multiple devices and accelerates project timelines. I/O options such as IRIG-B, Trip Coil Monitor, URTD interface, and Sensitive Ground Input support precise timing, trip coordination, and enhanced fault detection, facilitating robust, synchronized protection across multi-transformer installations. A one-year Eaton warranty and access to Eaton support ensure ongoing reliability, serviceability, and quick issue resolution as part of a comprehensive protection strategy.
