FAQs

For installation, mount the unit using its semi-flush mounting method and connect the removable terminals. Power it from 19-300 Vdc or 40-250 Vac, then wire the 8 digital and 2 analog inputs, 9 outputs, and Modbus RS485 communications. Follow the included Eaton datasheets for wiring diagrams and sequence of operations to ensure proper protection and diagnostic access.
The relay supports voltage, current, differential, and power protection and metering with 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs. Communications are via Modbus RTU or DNP3 RTU over RS485, enabling integration with SCADA systems and remote diagnostics.
Yes. With 50/60 Hz operation, a wide power supply range, and the ability to monitor multiple protection parameters, the ETR-5000-2B0BA0 is well-suited for transformer protection in substations and industrial plants, offering reliable trip coordination and data for asset health monitoring.
Compliance details are market-dependent. Refer to Eaton's datasheets and the provided downloads for certification information (CE, SIL, IP ratings where applicable). When in doubt, contact Eaton support to confirm current certifications for your region and application.
ROI is driven by reduced downtime, fewer nuisance trips, and improved maintenance planning through remote monitoring and diagnostics. The device’s warranty (one year from installation or 18 months from shipment) reflects confidence in reliability, while its integration with Eaton’s protection ecosystem lowers training and commissioning costs.
