The transformer relay supports a wide power supply range of 19-300 Vdc and 40-250 Vac, with a 50/60 Hz frequency rating. This flexibility reduces the need for multiple regional variants and simplifies spare-part inventories, speeding up commissioning. In practice, technicians deploy the ETR-5000-2A3IA1 across mixed-voltage panels and transformer rooms, cutting wiring errors and project lead times. Eight digital inputs and nine outputs, with removable terminals and projection mounting, streamline wiring and maintenance. The compact, rugged projection-mount design saves panel space and supports quick field upgrades without rewiring. This translates into faster startup, easier expansion, and lower installation labor costs during retrofits. Modbus/RTU over RS-485 and Modbus/TCP over Ethernet RJ-45 provide versatile SCADA integration and remote diagnostics. Operators connect to existing control systems without custom adapters, leveraging standard protocols for alarms, metering, and setpoint updates. The result is faster fault isolation, better asset visibility, and reduced mean time to repair. I/O options such as Sensitive Ground Input, IRIG-B timing, URTD interface, and Trip Coil Monitor support advanced protection schemes and diagnostics, improving fault reporting and testability while ensuring reliability. Zone selective interlocking (ZSI) at 2 enables coordinated tripping that minimizes system disturbance and improves negotiability during sectional faults. Wide voltage and current sensing capabilities facilitate retrofit compatibility with legacy equipment and new protection architectures. Warranty coverage follows Eaton’s policy, with a one-year term from installation or eighteen months from shipment, whichever comes first.

FAQs

Plan for its projection mounting and removable terminals to simplify wiring and field upgrades. Ensure a wide voltage supply is available (19-300 Vdc or 40-250 Vac) and allocate space for 8 digital inputs and 9 outputs. Use appropriate torque settings and labeled terminations to minimize wiring errors during commissioning and future expansions.
The relay supports Modbus RTU over RS-485 and Modbus TCP over Ethernet RJ-45. Connect to existing control networks using standard protocols for alarms, metering, and setpoint updates. For best results, use shielded cables for RS-485, ensure proper termination, and align baud rates with your SCADA master to optimize communication reliability.
Yes. With zone selective interlocking (2), 5 A and 1 A phase current sensing, and robust protection logic, it is designed for transformer protection across substations and manufacturing facilities. It supports mixed-voltage environments and integrates with protection schemes for fast fault isolation and reduced downtime.
Certification details vary by region. For global deployment, consult Eaton documentation for applicable CE, SIL, and IP ratings relevant to your jurisdiction. Ensure installation follows Eaton’s warranty policy and local electrical standards to maintain compliance and optimize lifecycle support.
Expect reduced downtime due to faster fault detection and isolation, consolidated protection electronics lowering spare-part inventory, and easier retrofits thanks to a wide input range and SCADA-ready communications. The removable terminals and projection mounting simplify maintenance, while Zone Selective Interlocking minimizes disturbance during fault events, improving overall plant availability.
