Structure features
1.Removable button head, which can be cooperated with arc-shortening rod.
2.Fuse element: eutectic alloy which can be melted at low temperature to avoid the burning of arc-extinguishing tube.
3.High strength strain wire, which can withstand the tensile strength from fuse cut out flipper and outside pulling strength.
4.Swagged connected end, guarantees the reliable connection of elements and are not easily damaged.
5.Swagged cable section prevents splaying of standards of cable, to ensure the cable’s smooth withdrawal from tube during the melting of fuse link.
6.Tinned copper stranded cable, resists corrosion, its cable diameter can resist corona.
7.Auxiliary arc-extinguishing tube, improves the capability of interrupting low fault current, and has the special ability to interrupt full range fault.
