              1 upper terminal block (tinned 3um, designed double-slot and upper contact piece connected, enhanced conductivity)
              2. Compression cap (tin plating, precise design greatly improves the splitting ability)
              3. Upper cover (hot-dip galvanizing 80um or more design break-and-hook joint)
              4. Upper moving contact (silver plated 3um, connected with the upper terminal block, enhanced conductivity)
              5. Upper moving contact rod (silver plating 3um, tightly matched with casting in the middle, enhanced conductivity)
              6. Fuse tube (anti-ultraviolet light has moisture absorption and long life)
              7. The trunnion (silver plated 3um) avoids shaking left and right when closing, and the accuracy is high)
              8. The trip unit (achieving the rapid separation of the terminal reduces the transmission force of the fuse when closing)
              9. High-strength insulator (self-cleaning ability, high strength, excellent process)
