Quick Summary

Eaton transformer relay ETR-4000 protects transformers in industrial automation applications. Engineers often face integration friction, limited diagnostics, and slow fault isolation when deploying protective relays. Compliance details vary by region; consult Eaton datasheets for CE, SIL, or IP ratings. This model uses Modbus RTU or DNP3 RTU over RS485 for secure communications, enabling seamless integration, faster fault isolation, and reduced downtime while supporting transformer protection, metering, and differential protection in complex distribution schemes.
