Eaton EBR-3000-2B0TB0 Bus differential relay - High impedance
Part Number: EBR-3000-2B0TB0
Quick Summary
The Eaton Bus differential relay is designed to provide fast differential protection for medium and large bus sections. Engineers often struggle with nuisance trips and slow fault isolation, especially during high-load conditions or coordinating protection schemes. Certification and approval considerations vary by region, and exact CE, SIL, or IP ratings are not listed here; consult Eaton for current approvals. The device supports 50/60 Hz operation, RS485 communications, and conformal coating, enabling robust field performance. With standard mounting and a 5 A contact rating, it integrates smoothly into existing switchgear, while 61850/MDBS/DNP3 support enables reliable remote signaling and monitoring for modern substations.
