FAQs

The ETR-5000-2B0FA1 uses removable terminals and a projection mounting method, which simplifies retrofits into existing switchgear footprints. It supports Modbus RTU or DNP3 RTU over fiber optics for secure SCADA integration, while providing 8 digital inputs and 9 outputs to align with current protection schemes without extensive rewiring.
Key specs include 2 analog inputs, 2 analog outputs, 8 digital inputs, 9 digital outputs, and a power supply range of 19-300VDC or 40-250VAC at 50/60 Hz. Protection coverage spans power and voltage metering, differential protection, and current protection with 5A/1A phase currents, enabling precise fault detection and fast isolation.
This relay is well-suited for transformer protection and metering in industrial plants, substations, and distributed energy schemes. Its modular I/O, bidirectional fiber communications, and zone-selective interlocking support coordinated protection, fault localization, and energy monitoring across medium- to large-scale transformer networks.
Compliances are listed as Manufacturer–verify with Eaton for region-specific certifications such as CE or SIL options. The product page notes general compatibility and warranty guidance; for exact SIL/CE/IP certifications, consult Eaton’s specification sheets and authorization channels to ensure alignment with your facility’s regulatory requirements.
With a one-year warranty (or up to 18 months from shipment per Eaton policy) and a base-relay architecture (ETR-4000), the device supports straightforward serviceability and upgrades. The fiber-based communications reduce cabling complexity, improve remote diagnostics, and can lower total cost of ownership by shortening maintenance windows and improving fault triage.
