Eaton EBR-3Z-2B0LB0-B Bus Differential Protection Relay

The Eaton EBR-3Z-2B0LB0-B bus differential relay is a panel-mount, high-impedance protection module designed for three-phase bus and equipment differential applications. Combining EBR-3000 and EBR-Z high-impedance modules in a common bezel, it supports MODBUS and DNP3 over fiber-optic LC and offers a 10.4 kJ energy withstand rating. Ideal for switchgear protection, transformer, generator and motor differential schemes where precise bus differential protection is required.

Key Features

• High-impedance differential protection for secure three-phase bus and equipment fault detection.
• Integrated module design: 3000-series and EBR‑Z high-impedance modules in a common bezel for compact installation.
• Communications: MODBUS and DNP3 protocols over fiber-optic LC interfaces for SCADA integration.
• Conformal coating for improved reliability in harsh or contaminated environments; standard panel mounting.
• Includes restricted earth-fault (REF) capability for grounded-wye and balanced earth-fault protection.
• Robust energy handling with a 10.4 kJ withstand rating for high-stress fault conditions.
