Yes. The current is what trips the fuse. Under normal operation, a fuse has almost zero voltage across it because its resistance is very low.

The maximum voltage rating on a fuse tells you about what happens when the fuse blows, at which point you have zero current but potentially a high voltage across the fuse terminals. You don't want arcing across a blown fuse, for example.
