The fuse you use is determined by the load on the circuit and the size wiring used in that circuit not the battery voltage.
The capacity of fuse is determined by the load current.
The size fuse should be noted on the old fuse.
The physical size of an atom is largely determined by the size of the electron cloud.
It is determined by the weight not the height
Fuse SizesThe Amperage ratings [sizing] of fuses [and circuit breakers] is determined by the SIZE of the conductors [wires] in the circuit which they serve.The size of the wires is determined by the maximum expected current [measured in Amperes (Amps) or Milliamps (mA] needed by the electrical devices "fed" by the circuit.Therefore, the answer to your question is that there are many different "size" fuses which range in Amperage from thousandths of an Amp to hundreds of Amps.
The Fuse size is listed on the under side of the Fuse Cover.
The short answer is, Yes. But here are the issues at hand: If you require a 15 amp circuit you cannot go smaller. Voltage of a fuse is determined by the voltage applied. You may not have 250v. You can use a fuse with a higher rating than the supply but not smaller. Wire size is determined by overcurrent protection, which is your fuse, so if you use a larger amp fuse you must determine if the wire is large enough to handle it. Do not guess. So the long answer is, Any 15 amp fuse with a voltage rating at or above the supplied voltage will work if properly installed.
By the size of the atom and its mass

The tag on the unit will tell you, minimum fuse size and maximum fuse size. Go wilth one in between.
The listing of fuse size and function is shown on the back size of the fuse box cover itself.
