RE -Installing an outdoor AOY25RWCL and wanted to find which fuse rating would it be 25 c rated breaker also for an AOY14 RNG,both are running ceiling wall units indoors.
Not inverter types
Cant find the info online.

If it's an inverter compressor then a 'B' or type 2 mcb will suffice.

If it's a full speed compressor then a 'C' or type 3 mcb will suffice.

MCB's with a 'D' or type 4 curve are meant for withstanding long inrush currents, as in Transformers or Infra-Red resistance heaters.

Don't forget that with an increase in mcb type (i.e. tripping curve), your Zs maximum is lowered.

The amperage rating of the MCB will be above and as close to the maximum full load current of the compressor, or as recommenned by the manufacturer.

Sorry I do not have the Fujitsu details you want, but I'm sure that one of the other members will be along soon to help

fujitsu electrical requirement for single phase 240V 50Hz:
12-14BTU fuse capacity 15A (running current ~6.2-7.8A)
18BTU fuse capacity 20A (running current ~8.5A)
24-30BTU fuse capacity 30A (running current ~12.1-14.5A)/
I would recommend C10 for AOY14RNG (power supply cord 2.5mm2) and C16 for AOY25RWCL (power supply cord 4.0mm2)
