Type No.: MAG-Fuse links
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. It have two type, type K fuse links And type T fuse links, The fast characteristics of Type K fuse links were to provide fuse links that would meet existing coordination Schemes. Type T fuse links provide slower time-current characteristics than the Type K links. Type T links coordinate particularly Well with automatic oilcircuit reclosers.
Materials used of Type K links.
The fusible section of the 1 through 3 ampere Type K links consist of a stainlesssteel 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.
Fuse elements of Type T fuse links 1 through 3 ampere Type T fuse links employ a fusing section consisting of a stainless-steel wire serving as both strain and fuse Wire; 6 through 100 ampere, a stainless-steel strain wire and a pure-tin fuse wire in parallel. 140 and 200 ampere T links have A copper element mechanically crimped at one end, soldered at the other end. On overloads or low faults, the solder becomes A fluid and the link separates; On higher fault currents, the link separates when the copper wire melts.
