Quick Summary

The Eaton transformer relay, ETR-4000-2A2CA1, provides robust transformer protection for industrial power networks and OEM equipment. This protection relay integrates current sensing, differential protection, and metering features to help you detect faults quickly and minimize downtime. Operators often struggle with integrating protection relays over Ethernet while maintaining accurate data collection and reliable communication. For procurement and field deployment, verify CE compliance and other relevant standards, and consider SIL-rated safety functionality and IP-rated environments where applicable. With Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45, you gain seamless interoperability with existing control systems, enabling streamlined maintenance, proactive diagnostics, and reduced engineering effort, along with scalable I/O for future expansion.
