Eaton EBR-3000-2B0IB1 Bus diff relay - High-Impedance
Part Number: EBR-3000-2B0IB1
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0IB1 delivers high-impedance protection for busbars in industrial power systems. Engineers frequently wrestle with nuisance trips and slow fault isolation that disrupt production. While this device supports 50/60 Hz operation and 5 A ratings, we also note conformance expectations and integration capabilities. Regulatory and safety considerations—CE or SIL-style certifications and IP-related protections—should be confirmed with Eaton for your project. In practice, this relay enables seamless SCADA integration via MODBUS/DNP3 while offering robust field installation with conformal coating and projection mounting. This translates to reduced downtime, quicker fault isolation, and clearer communication with protection schemes. Its 7.49 in by 8.62 in by 6.82 in footprint supports compact panel layouts.

FAQs
Installation begins with selecting a projection panel mounting location and verifying panel clearances for the 7.49 in x 8.62 in x 6.82 in footprint. Ensure proper wiring of protection currents and the 5 A ac/dc contacts, then apply conformal coating where required. Use standard torque values and verify conduit entries are sealed for environmental exposure. The unit’s compact form supports rapid retrofit and minimizes panel disruption while maintaining reliable protection.
Plan for 50/60 Hz operation, a 5 A contact rating, and a burden of 10 W / 17 VA. The device uses a projection panel mounting method and operates across -20 to 60°C ambient. Ensure compatible protection schemes and wiring with MODBUS/DNP3 (RS485 or RJ45) to integrate feedback signals into SCADA and control systems. These specs support fast, selective tripping with minimal nuisance trips.
Yes. The relay supports MODBUS/DNP3 communications over RS485 or RJ45, enabling direct data exchange with SCADA systems and protection relays. This integration improves fault visibility, timing coordination, and operator situational awareness. When wiring, ensure correct termination, proper shielding, and adherence to RS485 or RJ45 standards to maintain communication integrity in industrial environments.
