Largely these products provide single application circuit protection. Products that provide such benefits can be broken down into three main families: inline fuse holders, bolt-down fuse holders or fuse blocks, and finally power distribution modules. Count of fuses is a reliable indicator of which product family a product might fall into. Fuse holders generally holds one or two fuses. These products primarily hold, or mount fuses. Fuse holders also shield the critical protection elements of fuses from physical or electrical harm. Functionally, fuse holders also help to move fuses to easily accessible/convenient locations. This can be for sake of assembly integration or designed specifically for applications that require relatively frequent serviceability. Every fuse requires a holder to mount or connect into a circuit. This fact should be top of mind when assessing potential applications.
