For a toroidal transformer feeding a rectifier/smoothing capacitors you'll need a time delay (T) fuse as the switch on current surge can be VERY large.

When were at it, what type of fuses would you use for a PSU?
However if you have a fairly constant power drain you can reduce the surge by fitting a NTC thermistor in series
