Eaton EBR-3000-2B0KB1 Bus diff relay - 61850/MODBUS
Part Number: EBR-3000-2B0KB1
Quick Summary
The Eaton Bus differential relay is designed to protect busbars by detecting differential currents and triggering fast isolation in power distribution systems. Engineers often wrestle with nuisance trips and slow fault location in complex switchgear, especially under high-impedance fault conditions. Certification specifics vary by region; verify with Eaton for CE, SIL, or IP ratings, while the unit’s conformal coating and projection-mount design add ruggedness in harsh environments. By providing 61850/MODBUS/DNP3 communications and a compact form factor, it enables easier integration, retrofit, and scalable protection strategies for industrial networks. Overall, this relay helps improve reliability, reduce downtime, and support smarter, data-driven protection schemes.
