Quick Summary

The Eaton transformer relay ETR-5000-2A3BA1 enables reliable transformer protection and monitoring in medium- and high-voltage feeders. Engineers often struggle to integrate protective relays that support modern communications while safeguarding critical transformer assets. Certifications and compliance for this class of equipment typically include CE marking, UL/IEC safety standards, and enclosure ratings; consult the official Eaton specification sheet for exact approvals. With Modbus RTU or DNP3 RTU over RS-485 and scalable I/O, this device helps reduce downtime, streamline maintenance, and improve SCADA integration. For design engineers, the combination of protection, metering, and communication reduces integration risk, accelerates project timelines, and supports predictive maintenance strategies. Its eight digital inputs, nine outputs, and flexible 19-300 VDC / 40-250 VAC supply range support a single, scalable solution across multiple transformer configurations.

FAQs

Install Eaton ETR-5000-2A3BA1 by projecting-mounting the unit into a compatible switchgear or panel and securing removable terminals for quick servicing. Wire eight digital inputs, nine digital outputs, and two current-sensing inputs according to the wiring diagram, then connect the power supply (19-300 Vdc or 40-250 Vac). Finally, configure Modbus RTU or DNP3 RTU over RS-485 for SCADA communication and zone selective interlocking.
Best suited for transformer protection, metering, and monitoring within substations and plant feeders, the ETR-5000-2A3BA1 supports voltage protection, differential protection, and current protection with metering. Its 8/9 I/O and Modbus/DNP3 communications enable integration with existing protection schemes and SCADA. Zone selective interlocking and a compatible base relay (ETR-4000) simplify upgrades in legacy installations.
Verify communication protocol (Modbus RTU or DNP3 RTU over RS-485), supply compatibility (19-300 VDC / 40-250 VAC, 50/60 Hz), and I/O counts (eight inputs, nine outputs) to match your protection logic. Ensure the installation allows removable terminals and projection mounting for fast field commissioning, and confirm the wiring and grounding meet local electrical codes.
Compliance details are listed in Eaton's documentation; this includes regulatory approvals such as CE marking and safety standards where applicable, plus installation and warranty guidelines. Since models may vary by region, verify the precise certifications with Eaton's specification sheet and your local compliance authority prior to installation.
Deploying the ETR-5000-2A3BA1 reduces downtime by enabling rapid fault isolation and remote SCADA visibility. The device’s one-year warranty (eighteen months from shipment in some cases) and upgrade path via the ETR-4000 base relay simplify asset lifecycle management, lowering maintenance costs and extending transformer uptime in utilities and industrial facilities.
