Feature → Business Impact → Application: 8 digital inputs and 9 outputs enable comprehensive protection logic and local control without external relays, reducing wiring complexity and fault diagnosis time in transformer protection schemes used in substations and industrial plants. This hardware footprint translates to faster panel buildouts and easier diagnostics during commissioning and maintenance. Feature → Business Impact → Application: Power supply range of 19-300 VDC and 40-250 VAC supports both DC control circuits and AC control power, enabling seamless integration with legacy plant electrical infrastructure and new automation architectures while preserving energy efficiency. Feature → Business Impact → Application: Removable terminals simplify field maintenance and asset replacement, minimize downtime during upgrades, and support safer, quicker lugs reconfiguration in live environments. Feature → Business Impact → Application: URTD interface, Trip Coil Monitor, IRIG-B, and Sensitive Ground Input expand monitoring and fault diagnostics, improving protective coordination, event recording, and safety in critical transformer installations. Feature → Business Impact → Application: Modbus/DNP3 TCP over LC duplex fiber Ethernet provides robust, remote communication for SCADA, asset management, and predictive maintenance programs, reducing on-site visits and enabling real-time decision-making. Feature → Business Impact → Application: Zone selective interlocking (2) reduces system-wide tripping and improves service continuity by enabling targeted fault isolation in multi-transformer configurations typical in utility substations and large industrial campuses. Feature → Business Impact → Application: 50/60 Hz operation with a broad sensing range and precise current protection supports reliable transformer protection across diverse power networks, contributing to improved reliability metrics and reduced operational risk. These capabilities collectively support efficiency gains, compliance assurance, and a lower total cost of ownership for transformer protection retrofits and new builds.

FAQs

The ETR-5000-2A2KA0 installs with removable terminals and a semi-flush mounting method, simplifying field wiring and future upgrades. Its 8 inputs and 9 outputs provide integrated protection logic, reducing external relay modules and saving panel space. For OEM deployments, plan enclosure access and cable routing to support URTD interfaces and Trip Coil Monitor integration while maintaining clear fault-path signaling.
Key specs include a power supply range of 19-300 VDC and 40-250 VAC, 50/60 Hz operation, 8 digital inputs, 9 digital outputs, and 2 current sensing inputs. The device supports Modbus and DNP3 TCP via fiber Ethernet, enabling reliable SCADA communication and remote supervision in mixed DC/AC plant environments.
Yes. The relay provides Modbus and DNP3 TCP communication over LC duplex fiber Ethernet, enabling seamless integration with SCADA, asset management, and predictive maintenance platforms. This capability reduces on-site visits while improving visibility into transformer protection events and health data.
The ETR-5000-2A2KA0 supports 2-zone selective interlocking, enabling targeted tripping of faults within a transformer bank or substation. This minimizes system-wide outages, preserves critical loads, and improves fault isolation accuracy, which is especially valuable in large facilities with multiple transformers and complex protection schemes.
The device follows Eaton’s standard warranty policy, providing one year from date of installation or eighteen months from shipment, whichever occurs first. For ongoing performance, engineers should leverage available Eaton datasheets, application notes, and the E-Series specification resources to ensure proper configuration, calibration, and periodic diagnostics.
