FAQs

Begin by removing the terminal blocks to access the removable terminals, then mount the ETR-5000-2B3KA0 in the panel using the semi-flush mounting approach. Connect the 8 digital inputs, 2 analog inputs, 2 analog outputs, and 9 outputs to your protection logic and metering scheme. Use the IRIG-B or URTD interfaces for timing and synchronization as needed, and ensure the power supply is within 19-300 Vdc or 40-250 Vac. This approach minimizes wiring complexity and supports quick field upgrades.
Verify the power supply range of 19-300 Vdc and 40-250 Vac, the 50/60 Hz frequency rating, and the phase current options of 5 A and 1 A. Confirm 8 digital inputs, 2 analog inputs, 2 analog outputs, and 9 digital outputs align with your control logic. Also ensure the Modbus/DNP3 TCP over fiber interface is compatible with your SCADA network.
Yes. The device is designed as a transformer protection relay with integrated metering capabilities. Its 8/9 IO configuration supports essential protection schemes, while 2 analog inputs/outputs enable metering data. Interfaces like IRIG-B and URTD support precise timing and input conditioning, making it suitable for substation protection and monitoring tasks when paired with compatible SCADA systems.
Certification specifics are documented in the official Eaton specification sheet. Compliance details, including CE/UL or IP ratings, vary by installation and region. Refer to the Eaton datasheet (ETR-5000-2B3KA0.pdf) or contact Eaton support to confirm regional approvals before procurement.
The product follows Eaton Selling Policy 25-000, offering a one-year warranty from the date of installation or eighteen months from shipment, whichever occurs first.
