FAQs

Begin by verifying supply voltage compatibility (19-300 VDC or 40-250 VAC) and mounting the unit in a semi-flush position. Connect the removable terminals according to the protection scheme, then wire the 8 digital inputs, 2 analog inputs, 2 analog outputs, and 9 outputs as per the transformer protection logic. Finally, configure Modbus RTU or DNP3 RTU over RS-485 communications and verify operation with a commissioning switch or test sequence.
Key specs include power supply range 19-300 VDC / 40-250 VAC, frequency rating 50/60 Hz, phase current options 5A and 1A, 8 digital inputs, 9 outputs, and 2 analog inputs plus 2 analog outputs. Communications are via Modbus RTU or DNP3 RTU over RS-485, enabling remote monitoring and control within standard industrial networks.
Yes. Its broad input/output capabilities, multiple protection sensing options (differential, power, voltage, current metering), and RS-485 communication support make it suitable for transformer protection in substations and OEM applications. The device is designed for reliable protection coordination and easy integration into existing control architectures.
Certifications such as SIL, CE, and IP ratings are not listed in the provided data; confirmation should be obtained directly from Eaton for your regional requirements. Ensure the model’s compliances align with your safety and regulatory standards before field deployment.
The ETR-5000-2B1BA0 combines comprehensive protection with versatile communications, reducing commissioning time and enabling remote diagnostics. Its removable terminals simplify maintenance, and the wide voltage compatibility lowers spare-part investments. Over the life of the transformer asset, these factors translate to lower downtime and more predictable maintenance costs.
