Eaton EBR-3Z-2B0IA0-B Bus Differential Protection Relay

The Eaton EBR-3Z-2B0IA0-B is a high-impedance bus differential relay module combining the 3000 High Impedance and EBR‑Z high‑impedance modules in a common bezel. Designed for three‑phase bus differential protection and restricted earth‑fault schemes, it provides sensitive differential protection for switchgear, transformers, generators and motors. The relay supports MODBUS and DNP3 communications (RS‑485 or RJ45) and features a 10.4 kJ energy handling rating for robust protection in industrial and utility installations. Its utility-grade functionality supports both retrofit and new installations in substations and plant control rooms.

Key Features

• High‑impedance differential protection for three‑phase bus applications, optimized for sensitive fault detection.
• Combined 3000 and EBR‑Z high‑impedance modules in a common bezel for modular protection configurations.
• Supports MODBUS and DNP3 communications via RS‑485 or RJ45, enabling remote monitoring, integration and simple configuration.
• Restricted earth‑fault protection for grounded‑wye windings and balanced earth faults to improve selectivity.
• Standard panel mounting for straightforward installation into switchgear protection panels and control cubicles.
• 10.4 kJ energy handling capability to cope with fault conditions and improve relay robustness.

Technical Specifications

Applications
