String Level Arc Interrupter - PLC
Fonrich Arc Fault Circuit Interrupter (AFCI) is a UL 1699B-certified device engineered to deliver superior AFCI protection by detecting and interpreting arcing in ground-mounted PV systems. It effectively addresses arc issues by enabling arc fault detection at the string level, performing a targeted shutdown whenever an arc is detected.
Product Features & Advantages
This AFCI breaker system supports up to 1500V system voltages and accommodates unlimited string connections, offering exceptional flexibility for large-scale solar installations. Featuring real-time remote monitoring, it enhances AFCI protection performance, lowers maintenance costs, and complies with UL 1699B standards for arc fault circuit interrupters—making it a globally trusted solution for high-power PV environments.
