Eaton EBR-3Z-2B0GB1-B Bus Differential Relay

The Eaton EBR-3Z-2B0GB1-B (EBR-3000 series) is a bus differential protection relay engineered for three‑phase high‑impedance busbar and feeder protection. With wide auxiliary supply 40–250 Vac / 19–300 Vdc (50/60 Hz) and serial communications, it delivers selective bus, transformer, generator and motor differential schemes plus restricted earth‑fault detection for switchgear and distribution applications.

Key Features

• High‑impedance three‑phase differential protection for busbars, transformers, generators and motors, including restricted earth‑fault.
• Wide auxiliary supply 40–250 Vac and 19–300 Vdc for flexible installation environments.
• Serial communications: Modbus RTU and DNP3.0 RTU over RS‑485 (D‑SUB); IEC 61850 capability listed for integration.
• Input/output complement: 4 digital inputs and 4 outputs, sensitive ground input and IRIG‑B time synchronization support.
• Control/trip relay contacts with contact ratings shown in datasheet (1 A and 5 A types) for interfacing to breakers and control logic.
• Projection panel mount form factor and wide operating temperature range for indoor switchgear panels.
