Quick Summary

Eaton transformer relay protects transformer assets by monitoring essential electrical parameters and triggering protective actions in industrial power systems. This solution helps engineers avoid delays when integrating protection with SCADA and field devices, reducing inrush and fault propagation. While many relays struggle with protocol compatibility, the ETR-4000-2A0GB0 supports Modbus RTU or DNP3 RTU over RS-485, with 8 digital inputs and 9 outputs, enabling seamless communication, faster fault isolation, and improved system reliability. The design incorporates a removable terminal block and conformal-coated circuit boards for harsh environments, delivering robust protection while enabling straightforward installation and service. This product is particularly valuable for transformer protection applications in manufacturing plants and utility-lac systems seeking scalable, standards-based protection with clear diagnostics.
