You buy it at an electrical shop..

Its called a 60A cut out fuse and holder.. or 60A/100A as they're the same dimensions

Inside should be is a HRC (high rupture capacity slow blow) ceramic fuse with a fixed or replaceable fusible link. That's the name for the fuse wire..

You'll need to brace yourself so you don't fall when you pull it out (or push it in) as the connectors are spring loaded to maintain a very tight fit.
