The 3 Amp is at ANY voltage, the 250 just means that is the MAXIMUM voltage the fuse WON'T short at. (Max open circuit voltage it can keep open, when it blows without arcing).
Therefore- the fuse will blow at 3+ amps, even at 120 volts. Depending if it is a fast-blow or a slow-blow fuse, it could go in a fraction of a second, or 30 seconds or longer, also depending on the exact amps going though it.
My guess is that you need at least a 7 amp slow blow fuse, and might be able to use a 10 amp. Fuses are supposed to be oversized by 20% or so.
