FAQs

Installation is facilitated by the unit's projection mounting and removable terminals, designed for quick field setup. It supports a wide power-supply range of 19-300 Vdc and 40-250 Vac, with 50/60 Hz operation. Ensure your control system uses RS485 for Modbus RTU or DNP3 RTU and that the base relay is the ETR-4000 or compatible compatible model. Confirm wiring for the 8 inputs and 9 outputs, and plan for the two analog channels for precise monitoring.
Key specs include 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, and voltage/current/metering protection across 50/60 Hz. The device supports 19-300 Vdc or 40-250 Vac power, Modbus RTU or DNP3 RTU over RS485, and a zone selective interlocking feature with 2 zones. These specs enable comprehensive protection, fast fault isolation, and accurate transformer metering.
This relay is well suited for transformer protection in substations, industrial power distribution, and data centers where reliable protection, remote monitoring, and integration with SCADA are critical. Its flexible IO and RS485 communications support scalable protection schemes, while the ETR-4000 base relay ensures compatibility with existing Eaton protection architectures.
Compliance details are managed by the manufacturer. For critical deployments, request confirmation of CE, SIL, and IP ratings directly from Eaton. The product listing indicates standard compliance, with formal documentation available upon inquiry to ensure alignment with regulatory and safety requirements for your region and industry.
The ETR-5000-2B3BA1 reduces downtime through faster fault isolation, remote monitoring via RS485 communications, and robust protection covering voltage, current, differential, and power metering. A one-year warranty (with Eaton's policy) and the reusable ETR-4000 base relay lower lifecycle costs. Removable terminals and projection mounting simplify maintenance and upgrades, delivering favorable total cost of ownership.
