Quick Summary

The Eaton ETR-4000-2A3HA0 Transformer Relay is a high-performance protection device designed for transformer protection in industrial power systems. Engineers often struggle with integrating protection, metering and remote monitoring across diverse networks; this relay consolidates protection logic, metering, and communications into a single, scalable unit. Compliance details are manufacturer-provided; site requirements typically call for CE marks, SIL readiness, and IP enclosure ratings. With 8 digital inputs, 9 outputs, dual power options (19-300 VDC or 40-250 VAC) and Ethernet-based protocols such as 61850, M‑Bus TCP or DNP3 TCP/UDP, it supports seamless SCADA integration and fast fault isolation. Operational efficiency and reduced engineering costs come from its integrated zone selective interlocking and versatile I/O options.
