Eaton EBR-3Z-2B0TA1-A Bus Differential Protective Relay

The Eaton EBR-3Z-2B0TA1-A is a high‑impedance bus differential protection relay module supplied in a common bezel (projection mount) for panel installation. This protection relay supports three‑phase differential schemes and restricted earth fault detection, with a 10 A control/load interface and communications including IEC 61850, Modbus/DNP3 over RS-485 (RJ45). Designed for switchgear, transformer, generator and motor differential protection in substations and industrial plants.

Key Features

• High‑impedance differential protection for sensitive busbar fault detection.
• Combined 3000 and EBR‑Z high‑impedance modules in a common bezel for compact installation.
• Supports IEC 61850 and serial protocols (Modbus / DNP3) via RS‑485 (RJ45).
• Provides three‑phase differential protection for transformers, generators and motors.
• Restricted earth‑fault (REF) capability for grounded‑wye windings or balanced earth faults.
