Eaton Bus differential relay EBR-3000-2B0GB0 - Modbus/DNP3
Part Number: EBR-3000-2B0GB0
Quick Summary
The Eaton Bus differential relay protects feeders by monitoring differential current in electrical buses. Nuisance trips and slow fault isolation plague feeders; this relay improves selectivity and reliability. SIL readiness, CE compliance, and IP-rated robustness are highlighted in Eaton's design, with final certification details available from the manufacturer. Feeder protection in industrial facilities is optimized by its Modbus RTU + DNP3.0 RTU interface, enabling seamless integration with SCADA and energy management systems. With a compact footprint and removable terminals, installation is straightforward in control cabinets and switchgear assemblies. Operational efficiency and reduced maintenance costs come from its low burden, wide power supply range, and robust 40-250 Vac / 19-300 Vdc support.

FAQs
The device supports 19-300 Vdc and 40-250 Vac, with removable terminals and a standard mounting method, making it compatible with typical control cabinets and switchgear. Ensure the power supply meets the specified ranges and that RS485 communication lines are routed away from high-noise sources to preserve Modbus RTU and DNP3.0 RTU performance.
Verify 5 A contact rating, 8 digital inputs, 6 digital outputs, burden of 10 W / 17 VA, 50/60 Hz operation, and the broad power range (19-300 Vdc, 40-250 Vac). Also confirm the compensation for wiring length on RS485 and the availability of removable terminals for easy field replacement.
Yes. The EBR-3000-2B0GB0 supports Modbus RTU and DNP3.0 RTU over RS485 / D-SUB interfaces, enabling reliable integration with SCADA and energy management systems. Plan for termination, biasing, and shielded cabling to optimize communication reliability in noisy industrial environments.
The product is covered under Eaton's Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. For field service or replacement parts, reference the conformal coating and removable terminals as features that support safer maintenance and faster repairs.
Expect reduced nuisance trips and faster fault isolation due to precise differential protection. The wide input range and low burden lower total cost of ownership, while Modbus RTU + DNP3.0 RTU improve data visibility and SCADA integration. Overall, this enables higher uptime, easier upgrades, and lower maintenance costs in feeder protection schemes.
