Eaton EBR-3Z-2B0KB0-B Bus differential relay - 61850
Part Number: EBR-3Z-2B0KB1-A
Quick Summary
The Eaton Bus differential relay provides robust differential protection for medium-voltage bus configurations. Engineers struggle with nuisance trips and coordinating protections across multiple feeders. Compliances are manufacturer-confirmed, and the device supports 61850, MODBUS, and DNP3 communications with conformal coating designed for harsh environments. Its high-impedance design, common bezel, and EBR-Z module simplify integration into existing protection schemes. With a standard mount, energy handling of 10.4 kJ, and a 5 A contact rating, it delivers faster fault isolation, reduced downtime, and scalable protection for data centers, utilities, and industrial facilities.

FAQs
Install the relay using standard mounting in a common bezel with the EBR-Z High Impedance Module. Verify space for 7.49 in depth, 8.62 in height, and 13.64 in width, then connect power and signaling per the device's 50/60 Hz rating and 5 A contact outputs. The unit's 10 W burden minimizes wiring losses, and 12.7 lb weight makes handling straightforward.
It uses high-impedance protection to discriminate faults with minimal CT interaction, ensuring reliable operation even in complex bus configurations. The unit supports 61850/MODBUS/DNP3, conformal coating, and a common bezel with the EBR-Z module, enabling seamless integration and scalable protection coordination across substations and industrial plants. Additionally, its 10.4 kJ energy storage supports rapid energy release during fault clearing, improving tripping speed.
Yes. The EBR-3Z-2B0KB0-B is designed to pair with the EBR-Z High Impedance Module inside a common bezel, minimizing panel footprint and installation time. With standard mounting and 50/60 Hz operation, it slots into existing protection schemes and communicates via 61850, MODBUS, and DNP3, simplifying configuration and future upgrades.
It operates at 50/60 Hz and within -20°C to 60°C, with conformal coating for rugged environments. The device supports a 5 A contact rating and a 10 W / 17 VA burden, ensuring reliable signaling without heavy power draw. Its standard mounting and panel footprint (7.49 in depth, 8.62 in height, 13.64 in width; 12.7 lb) fit most control enclosures.
