Eaton EBR-3000-2B0IA1 Bus Differential Relay - High Z
Part Number: EBR-3000-2B0IA1
Quick Summary
Eaton Bus Differential Relay detects faults in busbar systems, protecting switchgear and feeders across industrial power networks. Many projects struggle with nuisance trips and improper selective coordination, especially during retrofits and expansions. Compliance details are provided by the manufacturer; verify CE marking, SIL, and IP-related certifications as applicable. Designed to work with the EBR-Z High Impedance Module, it supports precise fault discrimination when protection must be selective. With MODBUS/DNP3 communication over RS485 or RJ45 and a projection panel mounting approach, this relay enables scalable protection while simplifying installation and maintenance, reducing downtime, and lowering total cost of ownership for high-availability facilities. This aligns with industrial best practices for utility-scale and enterprise protection deployments. Engineers can count on uptime, traceability, and consistent performance under demanding temperatures.

FAQs
Installers should plan for projection panel mounting and the required EBR-Z High Impedance Module. Ensure enclosure space for a 7.49 in deep, 8.62 in high, and 6.82 in wide unit, and accommodate RS485 or RJ45 communication for MODBUS/DNP3. Verify the 5 A contact rating and 10 W/17 VA burden with your protection scheme and wire sizing.
High impedance bus differential protection provides selective fault detection by limiting current paths during faults, reducing nuisance trips and miscoordination with adjacent protections. This improves reliability in dense bus configurations and supports coordinated tripping schemes with upstream devices, which is critical during busbar faults and during commissioning of new feeders.
Yes. The relay supports MODBUS and DNP3 communication over RS485 or RJ45, enabling integration with SCADA systems and protection relays. This facilitates remote monitoring, diagnostics, and coordinated protection schemes, reducing site visits and enabling faster fault analysis while preserving data integrity and control authority.
Best suited for bus protection in substations, switchgear, and distribution feeders, the EBR-3000-2B0IA1 delivers high impedance differential protection with projection mounting. It is ideal where precise discrimination between bus faults and external disturbances is required, and where SCADA integration and modular protection platforms enhance reliability and maintenance efficiency.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Compliance details are provided by the manufacturer; verify CE marking, SIL ratings, and IP certifications as applicable for your region and application before deployment.
