What are fuse holders?

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
• Filament sheathed

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.
