Eaton EBR-3Z-2B0LA0-B Bus Differential Relay

The Eaton EBR-3Z-2B0LA0-B is a bus differential protection relay combining EBR-3Z and EBR‑Z high‑impedance modules in a common bezel, designed for panel mount installations. It provides three‑phase high‑impedance differential protection and restricted earth‑fault capability, supports MODBUS/DNP3 over fiber‑optic (LC) and includes a 10.4 kJ energy withstand rating — ideal for protection relay duties in switchgear, transformers, generators and large motor systems.

Key Features

• Three‑phase high‑impedance differential protection for busbars and protected zones.
• Combined EBR‑3Z and EBR‑Z high‑impedance modules in a common bezel, standard panel mount.
• MODBUS and DNP3 communications via fiber‑optic (LC) for SCADA integration.
• Removable relay connection assembly for fast maintenance and easy wiring access.
• Supports restricted earth‑fault (REF) protection for grounded‑wye or balanced earth faults.
• 10.4 kJ energy withstand capability for robust CT/relay stability under fault conditions.

Technical Specifications

Applications

Used for high‑sensitivity busbar protection in medium and high‑voltage switchgear, differential protection of transformers, generator and large motor differential schemes, and restricted earth‑fault detection on grounded‑wye windings.
