FAQs

Install the unit using the semi-flush mounting method and secure the removable terminals for wire access. Start with powering the device from 19–300 Vdc or 40–250 Vac, then connect the 8 digital inputs, 2 analog inputs, and 2 analog outputs along with the 9 outputs as required. Configure communications (Modbus/DNP3 TCP over fiber) and, if needed, enable IRIG-B timing for synchronized operations. This approach minimizes wiring errors and speeds commissioning while preserving future expandability via the ETR-4000 base.
Key specs include a power supply range of 19–300 Vdc and 40–250 Vac, operation at 50/60 Hz, 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. Protection features cover Current Protection and Metering, Differential Protection, Voltage Protection and Metering, and Power Protection and Metering. Communication options include Modbus and DNP3 TCP over LC duplex fiber, with IRIG-B timing and a Trip Coil Monitor for enhanced reliability.
Yes. The relay is designed for transformer protection, offering differential protection and metering alongside voltage and power protection. Its wide input range, rich I/O (8/9 channels), and robust fiber-based communications support integration into substations and OEM equipment. Features like URTD interface and IRIG-B timing improve synchronization and interoperability, making it suitable for both new installations and retrofit projects.
Compliances are listed as Contact Manufacturer, so confirm applicable certifications with Eaton for your installation. While typical practices emphasize CE, SIL, and IP considerations, exact certifications can vary by model and region. When engineering critical protection schemes, verify the precise regulatory approvals and testing requirements with Eaton to ensure the device meets your safety and reliability standards.
The ETR-5000-2B0KA0 supports remote monitoring via Modbus/DNP3 TCP, which enables proactive diagnostics and reduced on-site visits. Its removable terminals simplify wiring and maintenance, and Trip Coil Monitor reduces unrepaired faults by providing continuous protection visibility. Combined with a typical one-year warranty (or 18 months from shipment), these features contribute to lower downtime and faster fault resolution, delivering a favorable total cost of ownership.
