An inline fuse holder is a simple way to add circuit protection directly into a power wire. This specific fuse holder is designed to work with both ATO and ATC blade fuses and is installed in series, so if there’s a short or overload, the fuse blows and cuts power. The cover helps keep out dust and moisture, making it a reliable choice for automotive, marine, and general low-voltage wiring projects. The fuse holder has 300mm of 18AWG wire and includes a 5A ATO fuse.
