Eaton EBR-3Z-2B0FA0-B Bus Differential Protective Relay

The Eaton EBR-3Z-2B0FA0-B is a bus differential relay module that combines the 3000 High Impedance and EBR‑Z High Impedance modules in a common bezel. Designed for high-impedance differential protection, it delivers sensitive three-phase busbar and transformer/generator protection and includes a 10.4 kJ energy rating. Targeted at protection relay and switchgear applications, the unit supports modern communications (MODBUS/DNP3 over FO ST) for integration into utility substations, power plants and industrial distribution systems.

Key Features

• High-impedance differential protection for sensitive and stable three-phase bus schemes.
• Combined 3000 High Impedance plus EBR‑Z module in a common bezel for compact protection panels.
• Supports restricted earth fault (REF) protection for grounded-wye windings and balanced earth-fault detection.
• Communications ready with MODBUS and DNP3 over fiber-optic (FO ST) for SCADA/automation integration.
• Standard mount design suitable for retrofit into switchgear and protection cubicles; 10.4 kJ energy handling capability.
• Designed to maintain stability during through-faults and common CT mismatch conditions typical in bus protection schemes.

Technical Specifications

Applications

Typical uses include busbar differential protection in medium- and high-voltage switchgear, transformer differential protection, generator and motor differential schemes, and restricted earth-fault detection in utility and industrial substations.
