If you need a reliable fuse, this British Standard B3-size fuse from the RS PRO range will guard against high currents that trigger a short-circuit. You can attach and mount it easily to your fuse holder thanks to the integral bolts.

This fuse features a high rupturing functionality so it will withstand the high pressure involved in a short-circuit.
