I totally agree with Night Ryder. Fuses are used to protect cables to prevent damage in the event of excess current (ie.excess as far as the cable is concerned). As far as I know you cannot get anti-surge or 3.15A fuses for plug tops. If you use 5A fuses in the plugs connected to any of your computer equipment then this will afford you adequate protection. The reason your monitor needs an apparently over rated fuse is because the degaussing coils initially take a large current which quickly falls to a matter of a few milliamps.
