Model:FL11(33)KR1-200
Various Removable Button Head K Type Fuse Link Elements "K" "T" "H" 3 types, i.e. Fast melting type, Slow melting type, Slofast melting type. The rated voltage ranges are from 11 to 38kv, the rated current ranges are from 1A to 200A.
The fuse link is with removable button. Inside with high strength strain wire which can withstand tensile strength from fuse cutout flipper and outside pulling strength.
Jec Type fuse links are designed to carry 150% of their rated current without damage to the fuse link itself or the cutout in which it is installed. This capacity is for special loading situations, such as short time overloads and cold load pick-up.
Various Removable Button Head K Type Fuse Link Elements
K Type Fuse Link Elements are used for 11-38KV drop out fuse. The Fuse Element adopts the accurately tested material, high purity silver, or silver-copper eutectic or nickle-chrome eutectic, based on different rated current. The fuse element wire is extruded by mold of high accuracy. The cross section is inspected by laser micrometer to ensure the accuracy, while careful assembly guarantees no crack, shrinkage or twist which affects the time-current accuracy.

JEC K Type Fuse Link Elements assure system protection because they are precision manufactured. The fusible materials used in JEC Fuse Links are under continual control during manufacture. Pre-tested to guarantee their electrical values, these materials are held to precise tolerances. At critical points during the manufacturing process, rigid inspections are made.
