Fonrich FR-AFCI-KNJC String-Level Arc Fault Interrupter (AFCI) — PLC, 1500V

The Fonrich FR-AFCI-KNJC is a UL 1699B-certified string-level arc fault circuit interrupter built for ground-mounted PV plants. It listens to each string, identifies arcing signatures and performs a targeted shutdown of the affected string only, so the rest of the array keeps producing.

Key features

• String-level arc detection and fast arc extinguishing

• Supports system voltages up to 1500 V
• Real-time remote monitoring on the Fonrich platform
• Flexible deployment with no limitation on string connections
• PLC communication for data transmission
• UL 1699B certified
