Fuse holders are electronic devices that are used for containing, mounting, and protecting fuses. Fuse holders basically come in two types: open and fully enclosed. Open fuse holders are fuse blocks, clips, plug-in caps, and socket varieties. Fully enclosed fuse holders use a fuse carrier, which is inserted into the holder or some other part to fully enclose the fuse.
