 Arc Fault Protection Box

AFS8B Arc Fault Protection Box is a solar AFCI (Arc Fault Circuit Interrupter), which is mainly used in middle sizes of distributed PV system, such as 20~200KW rooftop solar system. Its main function is to detect the arc fault of the PV strings and disconnect the string cables when arc fault occurs.
