Selling Policy 25-000 - Distribution and Control Products and Services
Wide power-supply range and robust bus-differential core enable operation on both 19-300 Vdc and 40-250 Vac, reducing the need for multiple protectors in mixed-voltage setups. This flexibility translates to lower stocking costs, simpler spare-part planning, and faster commissioning in new feeders or retrofits. Eight digital inputs and six digital outputs provide intrinsic protection logic without external modules, supporting local signaling, interlocking schemes, and precise feeder protection in complex panels, data centers, and manufacturing lines. Modbus RTU plus DNP3.0 RTU over RS485 and D-SUB interfaces offer open connectivity for SCADA integration, remote configuration, and fault diagnostics across distributed sites, improving visibility and reducing downtime. A 10 W / 17 VA burden preserves cabinet cooling margins and energy efficiency in continuous protection duty, while standard mounting and removable terminals simplify installation and service. The device tolerates -20°C to 60°C and settles neatly into existing enclosures, shortening commissioning time and improving serviceability. With Eaton backing, warranty and support reinforce long-term reliability for critical feeders in industrial settings, enabling predictable maintenance and ROI.

FAQs
To install the Eaton EBR-3000-2B0GA0, mount the unit using the standard mounting method and secure removable terminals for quick service. Connect eight digital inputs and six digital outputs as required for your protection logic, wire the power supply within 19-300 Vdc or 40-250 Vac, and set up the RS485 Modbus RTU / DNP3.0 RTU communication. Verify proper grounding and ensure the panel enclosure supports the device’s -20 to 60°C operating range.
Key specifications include a wide power-supply range of 19-300 Vdc and 40-250 Vac, 50/60 Hz operation, 5 A contact rating, 8 digital inputs, 6 digital outputs, and a burden of 10 W / 17 VA. It uses Modbus RTU plus DNP3.0 RTU over RS485 and D-SUB for open, industrial-grade communication and easy panel integration.
Yes. The unit is designed for feeder protection with bus differential protection capabilities, detecting differential current between the bus and feeders to rapidly isolate faults. Its flexible IO and standard communication options support integration with existing protection schemes, SCADA, and remote monitoring in substations and industrial facilities.
The relay supports Modbus RTU and DNP3.0 RTU over RS485 and D-SUB interfaces, enabling straightforward SCADA integration, remote configuration, and fault diagnostics. For optimal results, ensure your SCADA system supports these protocols and maintain proper galvanic isolation to prevent ground loops in multi-site deployments.
