Quick Summary

The Eaton transformer relay ETR-5000-2A2BA1 is designed to protect transformers and feeders in industrial facilities by monitoring voltages, currents, and faults. Users often struggle with slow fault isolation and limited remote diagnostics, leading to extended downtime. Certification details vary by region, and this listing notes Compliances as Contact Manufacturer; typical transformer relays in this class align with CE marking and robust IP protection depending on the install context, with SIL levels defined per application. With Modbus RTU over RS485 and flexible power inputs, this device supports scalable protection, easier integration into SCADA, and a stronger business case for reduced maintenance costs and improved system uptime.
