Eaton EBR-3Z-2B0FB0-B Bus Differential Relay - High Impedance
Part Number: EBR-3Z-2B0FB0-B
Quick Summary
The Eaton EBR-3Z-2B0FB0-B bus differential relay protects power systems with fast, high-impedance fault detection for industrial buses. It helps mitigate nuisance trips in complex, multi-bus networks by delivering selective protection and rapid fault isolation. While the data sheet notes general compliance through the manufacturer, exact certifications such as CE, UL or IP ratings should be confirmed with Eaton to ensure regulatory alignment. This solution also leverages MODBUS/DNP3 communications and conformal coating, enabling seamless integration with existing protection schemes. For procurement and lifecycle value, it supports standard mounting and modular upgrades, making it a practical choice for modernized, resilient electrical protection in manufacturing and utilities environments.

FAQs
The EBR-3Z-2B0FB0-B is designed for standard mounting and is compatible with the EBR-Z High Impedance Module in a common bezel configuration. Its dimensions (13.64 in wide, 8.62 in high, 7.49 in depth) and 12.7 lb weight suit control panels and switchgear assemblies typical in industrial power distribution. Ensure wiring and burden requirements (10 W / 17 VA) are met and that SCADA integration via MODBUS/DNP3 is available in the protection scheme.
Key specs include 50/60 Hz operating frequency, 5 A contact rating (AC/DC), and a burden of 10 W / 17 VA. The unit supports a wide operating temperature range from -20°C to 60°C and provides high impedance bus differential protection. It includes conformal coating for harsher environments and a 10.4 kJ energy rating to absorb transient energy during faults.
Yes, it is well-suited for bus differential protection in industrial power distributions, data centers, and factory environments. Its high impedance approach improves selectivity and reduces nuisance trips, while MODBUS/DNP3 enables integration with supervisory control and protection systems. Modular bezel and standard mounting simplify installation and future upgrades in evolving protection architectures.
The published data lists ‘Compliances: Contact Manufacturer,’ with no explicit CE, UL, or IP ratings shown. For regulatory compliance and site-specific standards, verify with Eaton prior to procurement. This ensures alignment with regional electrical codes and any industry-specific requirements applicable to your installation.
The relay supports modular replacement with a common bezel, reducing maintenance downtime and spare-part inventory. Its robust high-impedance protection minimizes fault-related outages and equipment damage, contributing to lower service costs and improved system reliability. The integration with MODBUS/DNP3 also lowers monitoring and diagnostic labor through remote access and faster fault diagnosis.
