Hi,
fuse voltage ratings is a good term to search with.
It's well-explained in the following document, page 2 and section: Voltage Rating-Fuses
**broken link removed**
"The voltage rating of a fuse is a function of its capability to open a circuit under an overcurrent condition. Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced. If a fuse is used with a voltage rating lower than the circuit voltage, arc suppression will be impaired and, under some overcurrent conditions, the fuse may not clear the overcurrent safely."
