Eaton EBR-3Z-2B0IA1-B Bus Differential Protective Relay

The Eaton EBR-3Z-2B0IA1-B is a bus differential relay designed for high-impedance differential protection of three-phase buses and equipment. Rated with a 10 A relay output and nominal 10.4 kJ energy handling, it supports MODBUS/DNP3 communications (RS-485 or RJ45) and fits 3000/EBR‑Z high-impedance modules in a common bezel. Ideal for switchgear, transformer, generator and motor protection applications requiring selective bus differential protection.

Key Features

• High-impedance three-phase bus differential protection for precise fault detection in switchgear and busbars.
• Compatibility with 3000 and EBR‑Z high-impedance modules in a common bezel for compact panel mounting.
• Communications support: MODBUS and DNP3 via RS-485 or RJ45 for SCADA and protection integration.
• Rated relay load of 10 A with removable relay connections for straightforward replacement and maintenance.
• Energy handling approximately 10.4 kJ to withstand fault conditions at module level.
• Supports transformer, generator and large motor differential functions plus restricted earth-fault schemes.
