Twin Pigtail Type K and T fuse links


The fast characteristics of Type K fuse links were established by ANSI/NEMA to provide fuse links that would meet existing coordination schemes.

Chance Type K 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-ups.

Fuse Elements

The fusible section of the 1 through 3 ampere Type K links consists of a stainless-steel fuse strain wire; the 6 through 10 ampere, stainless steel strain wire and a copper-alloy fuse wire; 12 through 100 amperes, 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.

Buttonheads and Lengths

Conforming to all applicable ANSI/NEMA specifications, Chance Type K links are available with a removable or solid buttonhead.

Note: Catalog Numbers shown are 23" overall length; also available in 26" length. For 26": *Solid head K or T links, change the last two digits from 23 to 26. †Removable head K or T links, drop the last two digits.

Twin Pigtail Type K and T 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.
