FAQs

Yes. The ETR-4000-2A2KA0 is designed as a transformer protection relay with a removable base compatible with Eaton's protection relay ecosystem. It shares common mounting and terminal conventions, and its 8 digital inputs and 9 outputs support seamless retrofit in many control panels. For retrofits, verify terminal spacing and ensure the URTD interface is available to align with existing Eaton equipment.
Key specs include dual power supply ranges 19-300 VDC and 40-250 VAC, 50/60 Hz operation, and two current sensing inputs used for protection and metering. It provides a differential protection framework and zone selective interlocking options to coordinate tripping. For SCADA integration, Modbus and DNP3 TCP over fiber are standard, facilitating fast, reliable data exchange.
Environmentally it excels in substations, data centers, and industrial plants requiring robust transformer protection with remote monitoring. The 8 input and 9 output configuration supports complex protection schemes, while removable terminals simplify maintenance in tight cabinets. The device is well suited for retrofits as well as new installations needing scalable protection and easy integration with existing control systems.
Compliance details are provided by Eaton; specific marks such as CE, SIL readiness, and IP ratings are available upon request and documented in the official datasheet. It is important to verify the exact certifications for your region and application, as these influence installation approvals and warranty coverage. Eaton also supports ongoing technical service to ensure sustained compliance.
Maintenance and ROI are improved by removable terminals, a modular base, and easy remote diagnostics via Modbus and DNP3 TCP over fiber. This reduces on site visits, speeds fault isolation, and minimizes downtime in mission critical facilities. The controller configurability via PowerPort-E shortens commissioning time, delivering faster time to value and lower total cost of ownership.
