Eaton ETR-5000-2A1KA0 Transformer Relay - 50/60 Hz

Feature → Business Impact → Application. The 8 digital inputs and 9 outputs enable complex interlocking and smart sequencing, reducing the risk of misoperation and enabling faster fault isolation in substations and industrial plants. This directly translates to improved uptime, lower repair costs, and easier compliance with zone selective interlocking strategies across feeders. Feature → Business Impact → Application. The wide power-supply range of 19-300 Vdc and 40-250 Vac supports diverse plant environments and reduces the need for multiple controllers, cutting spare-part inventories and enabling seamless integration with existing power architectures. Feature → Business Impact → Application. Removable terminals simplify field maintenance and relamping work, lowering downtime during wiring changes and facilitating rapid upgrades or replacements in retrofit projects. Feature → Business Impact → Application. Modbus and DNP3 TCP over LC duplex fiber Ethernet provide robust, long-distance communication with SCADA and historian systems, improving visibility, alarm management, and data-driven decision making in large facilities. Feature → Business Impact → Application. The I/O options including URTD Interface, Sensitive Ground Input, IRIG-B, and Trip Coil Monitor deliver advanced protection features such as precise ground fault detection and time-synced monitoring for coordinated protection schemes, boosting overall system reliability. Feature → Business Impact → Application. With 5 A/1 A phase current sensing and 50/60 Hz operation, the unit delivers accurate protection decisions across a range of transformer sizes, helping engineers tune protection curves for better selectivity and reduced nuisance trips.
