Bussmann Limitron Parts
Limitron is the Bussmann family of current-limiting fuses, most of them fast-acting. This page also carries Bussmann KAC high-speed fuses and Fusetron FNM time-delay midget fuses.
The parts here: KTK fast-acting midget fuses, KTK-R Class CC fuses, KAC high-speed fuses for rectifier and semiconductor protection, and FNM time-delay midget fuses.
How to spot one: KTK and KTK-R share the 13/32 x 1-1/2 in. midget body; the R marks the Class CC rejection end, which fits Class CC fuse holders that refuse ordinary midget fuses, so a plain KTK will not go into a Class CC holder. Fast-acting fuses (KTK, KTK-R, KAC) and time-delay fuses (FNM) are not interchangeable, and FNM is a 250 volt fuse while KTK, KTK-R and KAC are 600 volt fuses, so replace like with like at the same current rating.
