My understanding is... Colin is closer than Reckless. The Voltage rating is essentially a Maximum voltage, so a 240v rated fuse in a 6 volt Austin is fine. Just chose the right Amps and you are away.
The V=IR will give you the voltage drop across the fuse so in real fuses R is low enough for this to be tiny and is independent of the circuit voltage.
