Eaton EBR-3Z-2B0DA1-B Bus Differential Protection Relay, 10A

The Eaton EBR-3Z-2B0DA1-B (EBR-3000 family) is a bus differential protection relay designed for three‑phase busbar, feeder, transformer, generator and motor protection. It accepts wide auxiliary supplies (40–250 Vac or 19–300 Vdc), uses standard 5 A input circuits and supports high‑sensitivity differential and restricted‑earth‑fault schemes. Suited to protection relay and switchgear applications where reliable, fast fault detection and secure communication are required.

Key Features

• High‑impedance three‑phase bus differential protection for sensitive fault discrimination.
• Restricted earth‑fault (REF) capability for grounded‑wye windings and balanced earth faults.
• Wide auxiliary supply range: 40–250 Vac or 19–300 Vdc for flexible installations.
• Profibus‑DP communication via fiber‑optic interface (ST connector) for secure data links.
• Low power consumption (10 W / 17 VA) and projection panel mount for compact switchgear fit.
• Compatible with 5 A ac/dc CT secondary circuits for standard protection wiring.

Technical Specifications

Applications

Used for busbar differential protection in medium‑voltage switchgear, transformer and generator differential schemes, feeder protection and selective tripping in utilities and heavy industry, and restricted earth‑fault protection on grounded‑wye windings.
