Eaton EBR-3Z-2B0GB0-B Bus differential relay - Modbus RTU
Part Number: EBR-3Z-2B0GB0-B
Quick Summary
The Eaton Bus differential relay protects feeders by detecting differential current and isolating faults in distribution systems. Engineers often contend with nuisance trips and lengthy fault localization that erodes uptime and drives maintenance costs. Compliance status, including CE, SIL, and IP ratings, should be confirmed with Eaton. Built for feeder protection, it supports Modbus RTU and DNP3.0 RTU for streamlined integration. This makes it ideal for industrial facilities seeking reliable protection and easy field upgrades across a wide voltage range. With eight digital inputs and six digital outputs, and a single current sensing input, it consolidates protection, control, and diagnostics in a compact package. The device operates from 19-300 VDC or 40-250 VAC, enabling flexible integration into existing plant power rails without redesign.
