FAQs

Plan for projection mounting and use the removable terminals for straightforward wiring. Connect the power supply within the 19-300 VDC / 40-250 VAC range and establish Modbus RTU or DNP3 RTU communication over RS-485 to the SCADA system. Configure eight digital inputs and nine outputs to match the transformer protection scheme, then test all protection functions in a controlled sequence.
Confirm eight digital inputs, nine digital outputs, two current-sensing inputs, and the power supply range of 19-300 VDC / 40-250 VAC with 50/60 Hz operation. Verify Modbus RTU or DNP3 RTU over RS-485 communications, compatibility with the ETR-4000 base relay, URTD interface options, and the conformal-coated circuit boards for harsh environments.
Yes. The ETR-5000-2A2GB1 is designed for transformer protection with metering and protection signaling, supports zone-selective interlocking, and offers robust communication options for SCADA integration. Ensure regulatory compliance through the proper CE/UL verification with Eaton and deploy in substations that require reliable remote monitoring and fast fault isolation.
The datasheet lists compliance as 'Contact Manufacturer,' so confirm CE/UL and IP ratings with Eaton before purchase. The product is covered by Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first, providing baseline protection against manufacturing defects.
Benefit from remote SCADA visibility and faster fault isolation, which reduces downtime and extends transformer life. The 8/9 I/O, robust protection logic, and modular installation support lower lifecycle costs, improve reliability, and streamline ongoing maintenance through easier diagnostics and integration with existing control architectures.
