Eaton EBR-3Z-2B0BB0-B Bus Differential Protective Relay, 10A

Eaton EBR-3Z-2B0BB0-B is a bus differential relay (10 A model) designed for three-phase high-impedance protection in switchgear, transformer and generator applications. It supports a wide auxiliary supply range (40–250 Vac / 19–300 Vdc) and serial telemetry via Modbus RTU and DNP3 over RS‑485, providing sensitive differential and restricted earth-fault protection for feeders, distribution buses and substation automation systems.

Key Features

• High-impedance differential protection for three-phase buses to detect and clear internal faults quickly.
• Restricted earth-fault capability for grounded-wye windings and sensitive earth-fault coverage.
• Integrated communications: Modbus RTU and DNP3.0 RTU over RS-485 terminals for SCADA integration.
• Wide auxiliary supply compatibility (40–250 Vac and 19–300 Vdc) with low power consumption (10 W / 17 VA).
• Designed for standard mounting in switchgear with reliable operation from -20°C to 60°C.

Technical Specifications

Applications

Typical uses include high-impedance bus protection in utility and industrial switchgear, feeder protection for distribution networks, transformer and generator differential schemes, and integration into substation SCADA via Modbus or DNP3 for remote monitoring and control.
