Eaton EBR-3Z-2B0TB0-A Bus Differential Relay

The Eaton EBR-3Z-2B0TB0-A is a bus differential protection relay combining a 3000 High‑Impedance module and an EBR‑Z High‑Impedance module in a common bezel. With a 5.2 kJ energy withstand rating and panel mounting, it provides selective high‑impedance differential protection for three‑phase busbars, switchgear, transformers, generators and large motors. Communications support (IEC 61850, MDBS, DNP3 over RS485 RJ45) makes it suitable for substation automation and modern protection schemes.

Key Features

• Integrated 3000 and EBR‑Z high‑impedance modules housed in a common bezel for compact protection panels.
• Three‑phase high‑impedance differential protection tailored for busbar and switchgear fault detection.
• Supports IEC 61850, MDBS and DNP3 communications via RS485 (RJ45) for seamless substation integration.
• Restricted Earth Fault (REF) and balanced earth fault protection for grounded‑wye windings and sensitive earth‑fault schemes.
• Conformal coating and standard panel mounting for improved resistance in industrial environments.
• Designed with a 5.2 kJ energy handling capability to withstand internal fault conditions and clearing operations.
