Yes, it is safe to go higher in voltage, but not under.

Our part number for the 3 amp version of this fuse is F-ZGMD-S3. We aren't able to verify that your application calls for a slow or a fast blow fuse, but this certainly meets all of the other requirements.

No brainer for me. Needed the fuses for one of my Marshallz. Got it up and running in no time. Naughty power tube popped. It happens. Really appreciated being able to find what I needed right away. I'm a loyal customer now.
