Eaton EBR-3Z-2B0FB1-B Bus Differential Relay - High Impedance
Part Number: EBR-3Z-2B0FB1-B
Quick Summary
The Eaton EBR-3Z-2B0FB1-B Bus differential relay provides fast differential protection for medium‑voltage bus sections in switchgear. Engineers often contend with nuisance trips and poor coordination that drive outages and maintenance costs. Specific certifications such as CE, SIL, and IP ratings are not listed in the data—confirm these with Eaton for your region and application. With its conformal coating, projection-panel mounting, and support for MODBUS/DNP3 (FO ST), the unit is built for harsh environments and easy integration. The combination of reliability, scalable protection, and a compact footprint translates into lower lifecycle costs and faster project timelines for electrical protection and control systems.

FAQs
Install using the projection panel mounting method specified for the device. Use the dimensions 13.64 in W x 8.62 in H x 7.49 in D as a fit check, secure wiring for the 5 A AC/DC contact rating, and allocate a 10 W / 17 VA burden. Ensure the unit is within its -20 to 60 C operating range and connect MODBUS/DNP3 (FO ST) for remote monitoring if required.
Key electrical specs include 50/60 Hz frequency rating, 5 A AC/DC contact rating, burden of 10 W / 17 VA, and an operating temperature range from -20 C to 60 C. The device is designed for bus differential protection with a high impedance configuration in a common-bezel setup.
Yes. The relay is specifically designed for bus differential protection with a high impedance module, enabling fast, selective fault isolation in switchgear environments and improving system reliability when integrated with EBR-Z modules.
