The Eaton EBR-3Z-2B0GB0-B (EBR-3000 series) is a bus differential protection relay offering high-impedance three-phase differential protection with a 5 A measuring input and wide auxiliary supply (40–250 Vac / 19–300 Vdc). Built for protection relay applications, it delivers secure bus and switchgear protection plus transformer, generator and motor differential schemes with SCADA-ready communications for utility and industrial installations.

Key Features

Three‑phase high‑impedance bus differential protection for secure fault discrimination.
Supports Modbus RTU and DNP3.0 RTU for integration with SCADA and protection systems.
Wide auxiliary supply range: 40–250 Vac and 19–300 Vdc for flexible installation.
5 A AC/DC measuring/input rating suitable for CT-based differential schemes.
Compact standard mounting and extended operating range (–20 °C to 60 °C) for switchgear environments.
