Eaton EBR-3000-2B0EA0 Bus Differential Relay - Profibus-DP RS485 Interface
Part Number: EBR-3000-2B0EA0
Quick Summary
Eaton bus differential relay protects feeders by detecting abnormal current imbalances in power distribution networks. Industrial teams struggle with nuisance trips and slow fault isolation that drive downtime and maintenance costs. Compliance details should be confirmed with the manufacturer; CE, SIL, and IP ratings may vary by region and product configuration. With 8 digital inputs, 6 outputs, Profibus-DP connectivity, and a broad power-supply range (19–300 Vdc / 40–250 Vac), this solution simplifies feeder protection, enables centralized control, and reduces wiring complexity for system integrators. By aligning with standard mounting and rugged operation (-20 to 60°C), it offers reliable performance across demanding environments.

FAQs
The Eaton EBR-3000-2B0EA0 is a bus differential relay designed for feeder protection in industrial electrical distribution. It provides eight digital inputs, six digital outputs, and Profibus-DP connectivity to PLCs/SCADA, enabling fast fault detection and reliable networked protection across 40-250 Vac or 19-300 Vdc power supplies.
It supports 40-250 Vac and 19-300 Vdc power, offering flexibility for mixed plant environments. This reduces wiring complexity, simplifies spares management, and eases retrofits without requiring separate power conversion equipment, while maintaining reliable operation at 50/60 Hz.
Yes, the relay includes Profibus-DP via RS485 with a D-SUB interface, enabling seamless integration with existing PLCs and SCADA systems. Proper RS485 wiring and termination practices should be followed to ensure robust network communication and avoid data collisions in multi-drop configurations.
Plan for standard mounting with removable terminals and ensure operation within -20°C to 60°C. The device has eight digital inputs, six outputs, and a 5 A contact rating, so design interlocks and signaling to minimize wiring while meeting control logic requirements.
