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 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.
