Eaton EBR-3Z-2B0CB1-B Bus Differential Relay

The Eaton EBR-3Z-2B0CB1-B is a bus differential relay module combining a 3000 high‑impedance element with the EBR‑Z high‑impedance module in a common bezel. With a 10.4 kJ energy capability and MODBUS/DNP3 (RJ45) communications, this protection relay is built for three‑phase bus differential, transformer, generator and motor differential schemes as well as restricted earth‑fault protection in switchgear and substation protection panels.

Key Features

• High‑impedance differential protection for secure bus and feeder fault detection on three‑phase systems.
• Three‑phase differential protection suitable for switchgear, transformers, generators and large motors.
• Restricted earth‑fault (REF) protection for grounded‑wye windings and balanced earth‑fault schemes.
• MODBUS and DNP3 communications over RJ45 for SCADA/RTU integration and remote monitoring.
• 10.4 kJ energy capability; conformal coating for improved resistance to harsh environments and projection panel mounting.
• Panel‑mount form factor designed for integration into protection panels and retrofit applications.

Technical Specifications

Applications

Protected uses include busbar differential protection in medium and high‑voltage switchgear, transformer differential and REF schemes, generator and large motor differential protection, and integration into utility and industrial protection panels for substations and power plants.
