Eaton EBR-3000-2B0HB0 Bus differential relay - High Impedance
Part Number: EBR-3000-2B0HB0
Quick Summary
Eaton Bus differential relay protects busbar systems by detecting differential currents to prevent faults. In practice, engineers grapple with nuisance trips, miscoordination between protection layers, and slow isolation that drives unplanned outages. The EBR-3000 family delivers robust performance for 50/60 Hz feeders, supports 61850/MODBUS/DNP3 communications over RJ45, and uses conformal coating for rugged environments. Note that specific certifications are not listed; typical requirements include CE compliance, IP ratings for enclosures, and SIL considerations—confirm with Eaton for your project. Beyond protection accuracy, the device supports conformal coating, standard mounting, and scalable integration with EBR-Z High Impedance Modules to grow with your system.

FAQs
Install the relay using its standard mounting method in a suitable enclosure, ensuring the EBR-Z High Impedance Module is compatible if you need expanded protection. Connect RJ45 toward your SCADA or protection system to enable 61850/MODBUS/DNP3 communication, and verify the 50/60 Hz power supply and the 5 A contact rating are suitable for your feeders.
Key specs include 50/60 Hz operation, a 5 A AC/DC contact rating, a burden of 10 W / 17 VA, and an operating temperature range of -20°C to 60°C. Communication is via RJ45 supporting 61850/MODBUS/DNP3, and the device integrates with the EBR-Z High Impedance Module for enhanced protection schemes.
Yes. The relay is designed for high-impedance differential protection on bus feeders and can be expanded with the EBR-Z High Impedance Module to suit larger or more complex protection schemes, delivering fast, selective tripping and improved system stability.
The datasheet notes that compliances should be confirmed with the manufacturer. While CE, IP, and SIL considerations are commonly relevant for protection devices, you should verify exact certifications with Eaton to meet your project and regulatory requirements.
The EBR-3000-2B0HB0 offers reliable protection with standard mounting, low electrical burden, and robust environmental resistance, reducing downtime and maintenance costs. The option to scale via the EBR-Z module supports future-proof protection, potentially lowering total cost of ownership over the equipment lifecycle.
