Quick Summary

ETR-5000-2B1CB1 is an Eaton transformer relay that delivers comprehensive transformer protection for medium to large electrical networks. This single package combines robust protection, monitoring, and communication to keep critical transformer assets safe and online. Engineers often struggle with reliable fault annunciation and integrating protection data into SCADA or automation systems, especially across mixed power rails. The device supports Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45, with 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs, enabling scalable control. Certification considerations: CE marking, SIL capability, and IP protection are important for regulatory compliance; confirm exact certifications with Eaton for your region. In practice, this translates to faster commissioning, better visibility, and lower total cost of ownership for transformer protection and metering tasks.
