Eaton EBR-3Z-2B0CA1-B Bus Differential Protective Relay

The Eaton EBR-3Z-2B0CA1-B is a high-impedance bus differential relay module for three-phase protection, offered in a projection-mount common bezel. Designed for bus, transformer, generator and motor differential schemes, it supports Modbus/DNP3 (RJ45) communications and a 10.4 kJ energy capability for robust fault handling. Ideal where fast, selective bus differential protection and restricted earth-fault coverage are required in industrial and utility switchgear.

Key Features

• High-impedance differential protection for sensitive and secure bus fault detection.
• Three-phase differential protection adaptable to switchgear, transformers, generators and motors.
• Restricted earth-fault (REF) capability for grounded-wye or balanced earth-fault schemes.
• Integrated communications: Modbus and DNP3 over RJ45 for SCADA and automation integration.
• Projection mount with common bezel compatibility for 3000 High Impedance and EBR-Z modules.
• Designed to withstand fault energy up to 10.4 kJ for reliable operation under through-fault conditions.
