Fuse holders are devices used for containing, protecting, and mounting fuses. Edward V. Sundt invented the first minor, fast-acting protective fuse designed to prevent sensitive test meters from burning out.
What are common types of fuse holders?
Fuse holders come in two basic types:
Open fuse holders
Fully enclosed fuse holders
Open fuse holders include fuse clips, fuse blocks, sockets, and plug-on cap varieties. The fully enclosed variety can be used as a fuse carrier inserted into a holder, but it can even enclose the fuse fully.
Common materials used for fuse holders
Typically, fuses are constructed using:
A thin metal strip
Where are fuse holders used?
A fuse holder's function is to ensure a robust current path (so that voltage does not creep to other components). It also ensures easier replacement of fuses. Fuse holders and fuses are usually placed in designated fuse boxes.
