Meet all applicable standards ANSI/NEMA
Type e 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 coveredin the ANSI standards.
Precision -The standard of fuse links
Fuse links assure system protection because they are precision manufactured. The fusible materials used in Fuse Links are under continual control uring 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.
Packaging
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
Materials used
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.
Application
The fast characteristics of Type K fuse links were established by ANSI/NEMA to provide fuse links that would meet existing coordination schemes. 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, Type klinks are available with a removable or solid button head.
Twin Pigtail type K cutout fuse links
We also supply Type K and Type T twin pigtails fuse link, The twin pigtails fuse link is convenient and easier to install in the fuse cutout than conventional single pigtail fuse links. The twin pigtails attach under the attachment stud on each side separately.
