Eaton EBR-3Z-2B0KB1-B Bus differential relay - High Impedance
Part Number: EBR-3Z-2B0KB1-B
Quick Summary
Eaton Bus differential relay is a high-impedance protection device for busbars, feeders, and switchgear in industrial power systems. This design helps installers and engineers avoid nuisance trips while speeding fault localization in difficult panel layouts. Certifications and compliance in this class typically include SIL-rated protection, CE-mark applicability for European markets, and rugged IP-rated housings suited to harsh environments. The EBR-3Z family also integrates 61850/MODBUS/DNP3 communications and a conformal-coated construction to reduce field maintenance. By combining reliable protection with flexible mounting and robust protection logic, this relay supports faster deployment, lower lifecycle costs, and improved overall system uptime for critical industrial processes.

FAQs
Compatibility starts with mounting and fit. The unit uses a projection panel mounting and a common bezel with the EBR-Z High Impedance Module, which simplifies retrofits in existing switchgear. Check enclosure depth (7.49 in), height (8.62 in), and width (13.64 in) to ensure clearances, and confirm that your bus arrangement can support high-impedance protection and the required communication interfaces (61850/MODBUS/DNP3). Always consult the Eaton datasheet and your panel manufacturer’s guidelines before installation.
Key specifications include a 50/60 Hz frequency rating, a 5 A AC/DC contact rating, a burden of 10 W / 17 VA, and an operating temperature range from -20°C to 60°C. The device supports conformal coating for harsh environments and a projection mounting method for straightforward installation. It also provides 61850/MODBUS/DNP3 communications for integration with modern protection schemes.
This relay is ideal for bus differential protection in substations and large switchgear assemblies. It excels in protecting bus sections against internal faults while minimizing nuisance trips. Its modular bezel and communication options make it well-suited for integration with SCADA, energy management systems, and remote monitoring in industrial facilities and critical infrastructure projects.
