                1 upper terminal (tinned copper casting and tin stamping)
                2. Upper cover (hot tin plating 80um, thickness 3mm)
                3. Upper contact piece (silver plated 3um, thickness 2.5mm)
                4. Upper moving contact (silver plated 3um, 304 stainless steel springs are subject to large pressure)
                5. Start-up hook (fork hook can effectively guide the fuse into the closing position)
                6. Fuse tube (anti-ultraviolet. It 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. Lower static contact (not visible) (the shunt plate silver plating current path is not connected to the plated chain pin)
                9. Jumper (provides fast end separation, cable strands pop up quickly)
                10. High-strength insulator (climbing distance 875mm) (self-cleaning ability, high strength, excellent craft)
