Eaton EBR-3Z-2B0KB1-B Bus Differential Protection Relay

The Eaton EBR-3Z-2B0KB1-B is a bus differential protection relay combining a 3000 High‑Impedance and an EBR‑Z High‑Impedance module in a common bezel. Designed for three‑phase high‑impedance differential protection, it supports IEC 61850, Modbus and DNP3 over fibre‑optic LC, features conformal coating and a projection mount, and includes a 10.4 kJ energy rating. Ideal for switchgear, transformer, generator and motor differential protection schemes where secure bus protection and fast communication are required.

Key Features

• High‑impedance differential protection for secure detection of internal faults on buses and windings.
• Dual‑module design: 3000 High‑Impedance and EBR‑Z High‑Impedance modules in a single bezel.
• Communications: native IEC 61850 plus Modbus and DNP3 via fibre‑optic LC for substation integration.
• Conformal coating and projection mount for improved reliability in harsh environments.
• Withstand/energy rating of 10.4 kJ to handle through‑fault energy during high‑stress events.
• Supports restricted earth fault and balanced earth fault protection for grounded‑wye systems.

Technical Specifications

Applications

Used for high‑security bus protection in medium and large switchgear, differential protection of transformers and generator sets, motor differential protection, and restricted earth fault schemes on grounded‑wye windings.
