Eaton EBR-3Z-2B0IB0-A Bus differential relay - High Impedance
Part Number: EBR-3Z-2B0IB0-A
Quick Summary
Eaton bus differential relay is a protective device for fast fault isolation in busbars used within switchgear and distribution panels. Operators often contend with nuisance trips and miscoordination when protecting high-impedance bus networks, which can drive unnecessary downtime and maintenance costs. Compliance details vary by region and are provided by the manufacturer—verify regional SIL, CE, or IP ratings with Eaton. With MODBUS/DNP3 communications, conformal coating, and a standard mounting approach, this model supports scalable, maintainable protection schemes across installed assets and evolving protection architectures in electrical protection & circuit control environments.

FAQs
Install the relay in a standard panel cutout using the common bezel approach and the EBR-Z high-impedance module. Ensure proper RS485 or RJ45 connections for MODBUS/DNP3, and confirm the device is within the -20°C to 60°C ambient range for reliable operation.
Key specs include 50/60 Hz operation, 5 A contact rating (AC/DC), a 10 W / 17 VA burden, and a 5.2 kJ energy rating. The product supports standard mounting and operates within -20°C to 60°C.
Yes. The device offers MODBUS/DNP3 communication over RS485 or RJ45, enabling remote monitoring, integration with SCADA systems, and improved diagnostic visibility for protection schemes.
Compliances are provided by the manufacturer and region-specific certifications should be confirmed with Eaton. Routine checks should verify ongoing connection integrity, ambient conditions, and that the conformal coating remains intact in harsh environments.
The common bezel with the EBR-Z module simplifies retrofits and upgrades, reduces panel footprint, and facilitates straightforward integration with existing protection architectures while preserving high-impedance protection characteristics.
