Model:DFL11(33)K(T)1-200
Double Tail K (T) Type Fuse Links comprises "K" "T" 2ypes, i.e. Fast melting type, Slow 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 double tail. 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.
Double Tail K (T) Type Fuse Links
K(T) Type double tail Fuse 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.

Structure of Fuse Elements
The fusible section of the 1 through 3 ampere Type K(T) fuse links consist of a stainless-steel fuse strain wire; the 6 through 10 ampere, stainless-steel strain wire and a copper-alloy fuse wire; 12 through 100amperes, a stainless steel strain wire and a silver-copper fuse wire; 140 and 200 ampere, a silver -copper fuse wire large enough to serve as both strain and fuse wire.
Conforming to all applicable ANSI/NEMA specifications, JEC Type K (T) Fuse links are available with a solid button head.
The twin pigtail fuse link is convenient to work with and easier to install in the cutout than conventional single pigtail fuse links. The pigtails attach under the clamp with one on each side of the attachment stud.
