The Eaton EBR-3Z-2B0HB1-B is a bus differential protection relay module engineered for high-impedance, three-phase protection of switchgear, transformers, generators and large motors. This configuration combines a 3000 high-impedance module with an EBR‑Z module in a common bezel, provides a 10.4 kJ energy capability and supports IEC 61850, Modbus and DNP3 communications over RJ45. Its conformal coating and projection mounting make it suitable for demanding utility and industrial protection relay applications.

Key Features

High-impedance differential protection tailored for three-phase bus systems.
Dual-module common bezel: 3000 high-impedance module plus EBR‑Z module.
Field communications: IEC 61850, Modbus and DNP3 via RJ45 port.
Conformal coating to resist moisture and contaminants in harsh environments.
Projection mount / standard panel fit for switchgear and control cubicles.
10.4 kJ capability to support effective fault detection and trip coordination.
