PCB mounts, or fuse holders, provide the installation hardware for a fuse. They are used in circuits to contain, protect and mount fuses. They are usually designed so that the wrong fuse cannot be placed in the mount, with a tab preventing accidental misuse.
Types of PCB mounts
PCB mounts come in two basic types, open or fully enclosed. Open PCB mounts include fuse clips, fuse blocks, socket and plug-on cap varieties. The fully enclosed variety may use a fuse carrier that is inserted into a holder or may use other means to fully enclose the fuse.
Both open and enclosed PCB mounts are available with a range of terminal styles including quick disconnect, solder and angled versions.
Why are PCB mounts important?
Fuses need to be protected because they themselves protect circuits from over current conditions. For example, if a circuit receives too high a level of current, the fuse will burn out, breaking the circuit. With a PCB mount, your fuse is protected and you can easily change it if required.
