Eaton EBR-3Z-2B0IB0-B Bus Differential Protection Relay

The Eaton EBR-3Z-2B0IB0-B is a panel-mounted bus differential relay providing high-impedance differential protection for three-phase systems. Rated with a 10 A relay output and a 10.4 kJ energy withstand, this protection relay supports MODBUS/DNP3 communications (RS-485 or RJ45) and conformal coating for harsh environments. It is engineered for busbar protection in switchgear, transformer and generator differential schemes, and motor protection, requiring fast, selective fault detection and flexible communications for system integration.

Key Features

• High-impedance three-phase differential protection suitable for busbars, transformers and motors.
• MODBUS and DNP3 communications via RS-485 or RJ45 for SCADA and protection integration.
• Panel mount design with removable connections for straightforward installation and servicing.
• Conformal coating for improved reliability in contaminated or humid industrial environments.
• 10 A relay output for tripping and a 10.4 kJ energy withstand rating for robust fault handling.
• Restricted earth-fault (REF) capability for grounded-wye windings and balanced earth-fault schemes.

Technical Specifications

Applications

Ideal for primary busbar protection in switchgear, differential protection of power and distribution transformers, generator and motor differential schemes, plant main bus protection, and utility substation feeder protection where fast, selective fault isolation is required.
