Eaton EBR-3Z-2B0IA0-B Bus differential relay - 10.4kJ
Part Number: EBR-3Z-2B0IA0-B
Quick Summary
Eaton Bus differential relay provides fast, high-impedance protection for medium-voltage buses in switchgear and data center applications. Designers often contend with nuisance trips and miscoordination during transient faults, risking downtime and costly fault clearing. Certification considerations include confirming manufacturer-supported specs and regionally required standards such as CE, SIL, and IP ratings where applicable. This model combines modular high-impedance protection with Modbus/DNP3 communications and a standard mounting footprint to support reliable, scalable protection schemes for modern power systems.

Feature → Business Impact → Application: High-impedance protection with 10.4 kJ energy storage minimizes false trips and improves selectivity in complex feeder layouts, reducing outage time and maintenance costs in data centers and manufacturing plants. The 50/60 Hz compatibility and 5 A contact rating deliver robust performance across regional power systems while maintaining precise fault clearance. Standard mounting and common bezel compatibility with the EBR-Z High Impedance Module simplify installation and future expansion, lowering commissioning time and hardware diversity in switchgear assemblies. The 10 W / 17 VA burden and compact enclosure support energy-efficient protection without imposing unnecessary power or space penalties on control rooms or equipment rooms. MODBUS/DNP3 communication over RS485 or RJ45 enables seamless integration with SCADA and automation platforms, enhancing visibility and control. Operating temperature range from -20°C to 60°C supports reliability in harsh industrial environments, while the included warranty provides business continuity and asset protection. This combination of robust protection and flexible communications makes it suitable for data centers, industrial plants, and utility-scale distributions, aligning with long-term reliability and ROI objectives.

FAQs
The EBR-3Z-2B0IA0-B uses a standard mounting method and a common bezel with the EBR-Z High Impedance Module. Begin by confirming 50/60 Hz supply, then mount the relay in a suitable panel region, route RS485 or RJ45 communications for MODBUS/DNP3, connect the 5 A contact circuits, and verify the 10 W/17 VA burden. Ensure operating temperature remains within -20 to 60 C and perform a functional test to confirm differential protection behavior. This approach minimizes commissioning time and supports scalable protection strategies.
Key specs include 50/60 Hz operation, 5 A contact rating, 10 W / 17 VA burden, and a high-impedance protection scheme with a 10.4 kJ energy capability. The unit features standard mounting, a footprint designed for common bezels, and compatibility with the EBR-Z High Impedance Module. These factors together support fast, selective fault detection and reduced nuisance trips across diverse industrial loads.
Yes. With high-impedance bus protection, MODBUS/DNP3 communications, and a standard mounting footprint, the relay integrates smoothly into data centers and industrial facilities. Its operate range (-20 to 60 C) and 50/60 Hz compatibility suit harsh environments, while the 12.7 lb enclosure and 10 W burden help manage space and power budgets. Consider pairing with the EBR-Z module for scalable, modular protection architecture.
Compliances are listed as 'Contact Manufacturer' in the data, so verify exact certifications with Eaton for your region and application. While CE, SIL, and IP ratings are common targets for industrial protection devices, confirm which standards apply to your installation and ensure any site-specific requirements are met before commissioning.
Expect improved uptime due to fast, selective fault isolation and reduced nuisance trips, which lowers maintenance and outage costs. The device’s compatibility with MODBUS/DNP3 and a common bezel supports scalable protection without large incremental hardware investments. A one-year warranty (or 18 months from shipment) provides protection during early life, contributing to a favorable total cost of ownership in data centers and industrial networks.
