Eaton EBR-3Z-2B0LA0-B Bus differential relay - High Impedance
Part Number: EBR-3Z-2B0LA0-B
Quick Summary
The Eaton Bus differential relay is designed to protect medium- and large-scale switchgear by detecting differential current in feeder buses. Engineers often contend with nuisance trips and slow fault isolation that erode uptime and drive maintenance costs. Certification readiness varies by market; CE and SIL readiness are common expectations, but exact certifications for this model should be confirmed with Eaton. This unit supports 50/60 Hz operation and standard mounting, delivering robust high-impedance protection with MODBUS/DNP3 communications for remote monitoring. By combining proven electrical performance with straightforward installation, it helps asset-intensive facilities reduce outage duration, improve fault diagnostics, and lower lifecycle costs.
