The Eaton EBR-3Z-2B0KB0-B is a high-impedance bus differential protection relay module designed for three-phase protection schemes. Featuring a 10.4 kJ energy withstand rating, integrated 3000 and EBR‑Z high-impedance modules, and IEC 61850/MODBUS/DNP3 over fiber (FO LC), this protection relay suits switchgear, transformer, generator and large motor differential protection in utility and industrial substations.

Key Features

High-impedance three-phase bus differential protection for switchgear and busbars.
Integrated 3000 and EBR‑Z high-impedance modules packaged in a common bezel.
Communications: IEC 61850, Modbus and DNP3 via fiber‑optic (FO LC); IRIG‑B timing support.
Extensive I/O: 8 digital inputs and 11 programmable outputs, with trip coil monitor option.
Rugged design with conformal coating and projection/standard mounting; 10.4 kJ energy withstand capability.
