Eaton EBR-3Z-2B0FA1-B Bus Differential Protective Relay

The Eaton EBR-3Z-2B0FA1-B Bus Differential Relay is a high-impedance protection module combining 3000 and EBR-Z elements in a common bezel. With a 10.4 kJ energy capability and projection panel mounting, it provides three-phase bus differential and restricted earth-fault protection for switchgear, transformer and generator bus applications. Suited for bus differential relay and transformer differential relay schemes, it supports utility and industrial motor control protection with modern communications.

Key Features

• High-impedance differential protection for three-phase bus systems and CT restraint stability.
• Restricted earth-fault (REF) capability for grounded-wye or balanced earth fault detection.
• Integrated 3000 High Impedance and EBR-Z High Impedance modules in a common bezel for compact installation.
• MODBUS and DNP3 communications over fiber-optic (FO ST) for secure remote integration.
• Projection mount / panel mounting designed for retrofit and new switchgear installations.
• 10.4 kJ energy capability to handle CT energy during fault conditions.
