Eaton EBR-3000-2B0BB1 Bus differential relay - Modbus RTU
Part Number: EBR-3000-2B0BB1
Quick Summary
Eaton EBR-3000-2B0BB1 bus differential relay provides fast feeder protection for industrial power systems. This helps prevent nuisance trips, reduces downtime, and keeps critical processes online. Compliances are to be confirmed with the manufacturer; CE, SIL, and IP considerations are region-dependent. In practice, it supports Modbus RTU and DNP3.0 RTU, enabling seamless integration with automation and monitoring architectures. This translates to faster fault isolation, lower energy waste, and clearer data visibility for maintenance teams. With eight digital inputs, six outputs, and a single current-sensing input, it integrates easily with PLCs and SCADA. Its projection-panel mounting and removable terminals simplify installation and future servicing in space-constrained panels.

FAQs
The EBR-3000-2B0BB1 is designed for projection-panel mounting and features removable terminals to simplify wiring. Plan a compact enclosure layout, mount the unit securely, connect eight digital inputs and six digital outputs, and route RS485 communication lines for Modbus RTU and DNP3.0 RTU. This configuration speeds commissioning and eases future servicing.
The relay supports a versatile power range of 19-300 VDC and 40-250 VAC, enabling installation across varied sites without a separate power conversion module. Ensure your feeder’s supply matches these ranges and verify frequency is within 50/60 Hz for reliable operation.
Yes. The EBR-3000-2B0BB1 includes Modbus RTU and DNP3.0 RTU communications over RS485 or terminals, allowing seamless integration with common SCADA and automation architectures. Use standard Modbus registers and DNP3.0 data points to monitor feeder health, report faults, and trigger rapid isolation.
The unit provides 8 digital inputs and 6 digital outputs with a 5 A AC/DC contact rating. It also includes 1 current-sensing input for monitoring feeder conditions. This combination supports detailed control logic and robust decision-making in protection schemes for feeders.
Eaton’s policy for the EBR-3000-2B0BB1 offers a one-year warranty from installation or eighteen months from shipment, whichever occurs first. For field support, consulting Eaton’s technical resources and distributor networks helps ensure timely maintenance, calibration, and configuration updates.
