                                                                          of high quality 304, precision cast brass and

                1 upper terminal (tinned copper casting hot tinned 3um)
                2. Top cover (using high quality 304 stainless steel and connected terminal blocks)
                3. Upper contact piece (connected body thickness 2mm) enhances electrical conductivity
                4. Upper moving contact (304 stainless steel spring is 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 (self-cleaning ability, high strength, excellent process)
