Abstract
A shock-safe fuse holder for a cartridge fuse is provided which can be readily installed in a mating receptacle and removed therefrom for fuse replacement. The fuse holder includes a visual indicator for denoting a blown or missing fuse. The cartridge fuse is substantially enclosed within the holder to limit the access to the electrical contacts of the cartridge fuse to minimize the danger of electrical shock. The holder has a configuration for retaining the holder in a mating fuse receptacle even in the absence of an installed fuse.
