Eaton EBR-3Z-2B0EA1-B Bus Differential Relay, 10A

The Eaton EBR-3Z-2B0EA1-B (EBR-3000 family) bus differential relay is a protection relay designed for three‑phase high‑impedance differential schemes. With wide supply ranges (40–250 Vac or 19–300 Vdc), Profibus‑DP communications and CT‑compatible inputs, it provides sensitive differential and restricted earth‑fault protection for switchgear, transformers, generators and motor feeder protection in industrial and utility substations. Panel‑mount construction makes it suitable for retrofit into low‑voltage switchgear and control panels, enabling integration with SCADA/automation systems.

Key Features

• High‑impedance three‑phase bus differential protection for sensitive fault detection in switchgear.
• Supports restricted earth‑fault (REF) protection for grounded‑wye or balanced earth‑fault schemes.
• Wide AC/DC supply range: 40–250 Vac or 19–300 Vdc for flexible panel installations.
• Profibus‑DP communications (RS485 / D‑SUB) for PLC/SCADA and protection-system integration.
• CT‑compatible inputs (feed specifies 5 A) and 50/60 Hz operation; low power consumption (~10 W / 17 VA).
• Projection panel‑mount design with operating range −20 °C to +60 °C for industrial environments.

Technical Specifications

Applications

Typical uses include high‑impedance bus differential protection in low‑voltage switchgear, transformer and generator differential schemes, motor feeder protection, and restricted earth‑fault protection for industrial, utility and commercial substations with SCADA integration.
