FAQs

The ETR-5000-2B3FB0 uses removable terminals and supports semi-flush mounting for straightforward field deployment. It references the base ETR-4000 family and is designed for integration with standard transformer protection schemes. Ensure panel space accommodates its 9.72 in width, 8.7 in height, and 8.06 in depth, and verify wiring for 8 digital inputs and 9 outputs, plus 2 AI/2 AO before commissioning.
The unit provides 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs to support complex protection and metering logic. Communications include Modbus RTU or DNP3 RTU over fiber optic ST, enabling secure SCADA integration and remote diagnostics across distributed transformers.
Yes. The ETR-5000-2B3FB0 is purpose-built for transformer protection and monitoring in electrical distribution. Its 50/60 Hz capability, wide power-supply range (19-300 VDC / 40-250 VAC), and multi-IO configuration support protective relaying, metering, and interlocking within substations, OEM panels, and transformer banks, reducing downtime and improving fault response.
Compliance details are provided by the manufacturer. The datasheet notes 'Compliances: Contact Manufacturer,' so verify CE, IP rating, SIL readiness, or other regulatory standards directly with Eaton to ensure alignment with your project requirements and local codes.
