12-27kv Length 584mm 6A Various Removable Button Head K Type Fuse Elements Fuse Links
Meet all applicable Standards ANSI/NEMA
JEC Type K and Type T fuse links are made in complete accordance with standards ANSI/NEMA. Other links meet all the standards except those covering time-current characteristics. Time-current characteristics for links other than K and T links are not covered in the ANSI standards.
Precision — The standard of JEC fuse links
JEC fuse links 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.
JEC fuse links come in protective plastic bags with perforations to facilitate quick, easy opening even when lineman’s gloves are worn. Each bag remains completely sealed for all-weather protection and keeps the links protected in the line truck’s bins.
Type and amperage is printed on each bag, for easy identification.
The fusible section of the 1 through 3 ampere Type K 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.
The fast characteristics of Type K fuse links were established by ANSI/NEMA to provide fuse links that would meet existing coordination schemes.
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 capacityis for special loading situations, such as shorttime over loads and cold load pick-up.
Button head and length
Conforming to all applicable ANSI/NEMA specifications, JEC Type Klinks are available with a removable or solid button head.
Twin Pigtail Type K fuse links
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.
