Is there a compatible breaker fuse?
I have seen these at Home Depot and a few other home stores. They are not cheap, about $10. I would be more concerned about why your fuses are blowing. Are the circuits overloaded? You need to determine that first. Don't even think about increasing the fuse/breaker size until you or someone else checks the wire size for the circuits. Just get a few boxes of the standard fuses and don't complicate things.
