The SFD range has been especially designed to associated with Type 1 SPDs. These very specific fuses are able to conduct huge surge currents in rather small dimensions to protect Type 1 SPDs against harsh current circuit failures. In order to comply IEC 61643-11 standards, AC power SPD must be protected against short circuit failures: these specific fusing disconnectors must be installed in the SPD branch.
