Type T links are available with a silver fuse element or tin fuse element. Fuse links with a silver fuse element are available in ratings from 6 to 200 A in removable and non-removable button head designs. Fuse links with a tin fuse element are available in ratings from 1 to 200 A in button head design and from 6 to 50 A in the open-link design. Type T links exhibit the same overload characteristics as similarly rated Type K links at the 300 or 600 s points. The time-current characteristics differ below these points. Hence, the T link is slower at the high-current end than the same size K link.
