Eaton EBR-3Z-2B0LA1-B Bus Differential Relay - 10.4kJ
Part Number: EBR-3Z-2B0LA1-B
Quick Summary
The Eaton Bus differential relay provides fast fault detection for power distribution busbars in switchgear and substations. In practice, engineers confront nuisance trips and downtime when differential faults occur; this relay targets that issue with high-impedance protection and a robust common bezel. Certification specifics are not listed in the data; consult Eaton for CE, SIL, or IP ratings to match your compliance program. With projection panel mounting and a shared bezel, installation is streamlined across panels, and MODBUS/DNP3 (FO LC) communications enable easy integration with existing SCADA. The unit supports 50/60 Hz operation and a 5 A contact rating, delivering business value through improved reliability and faster fault isolation.
