Eaton EBR-3Z-2B0HA1-B Bus Differential Relay

The Eaton EBR-3Z-2B0HA1-B is a high‑impedance bus differential relay combining the 3000 High Impedance and EBR‑Z modules in a common bezel. With a 10.4 kJ energy handling capability and IEC 61850 / Modbus / DNP3 (RJ45) communications, this protection relay provides sensitive ground detection and current metering for feeder, transformer, generator and motor differential schemes in switchgear and protection panels.

Key Features

• High‑impedance differential protection for three‑phase bus and equipment differential schemes.
• 10.4 kJ energy handling rating for resilient through‑fault performance.
• Networked communications: IEC 61850, Modbus and DNP3 over RJ45 for integration with substation systems.
• Built‑in sensitive ground input and trip coil monitor I/O options for earth‑fault and trip supervision.
• Digital I/O: 8 inputs and 6 outputs; zero analog inputs/outputs — suitable for discrete protection logic.
• Projection‑mount bezel for straightforward fitment into switchgear instrument cavities and retrofit projects.

Technical Specifications

Applications

Designed for three‑phase bus differential protection in medium and large switchgear; transformer differential schemes; generator and rotating‑machine differential protection; and restricted earth‑fault protection on grounded‑wye windings or balanced earth‑fault schemes.
