There is a formula for calculating the relation between volts amps and resistance (ohms) which is V=IR where v=volts, I=amps and R= resistance.
Thus a 6volt fuse rated at 6 amps would require a resistance of 1 ohm whereas a 12 volt 6 amp fuse will require a 2 ohm resistance and a 240 volt 6 amp fuse would need a 240/6 = 40 ohm resistor.
I can't see that a mains 6amp fuse would be suitable for a 6v application. Well it might, but it won't blow when you need it to.
