Need advice on fuse block for electric fans

Hoping someone can advise or confirm my assumptions. I have 2 electric fans and want to have one fuse per fan. When a fan initially kicks on, it draws 43-44 amps for about a second but then drops to around 20 amps. I already have 2 relays wired with a control module from Dakota.

Ideally I would like to add a 4 circuit fuse block to allow room for something in the future. Problem is most of the fuse blocks are a max of 30-40 amps per circuit. I know I would at least a 45-50 amp fuse to handle the initial draw. Any suggestions?

Would I be ok with a 50 amp fuse in a 30-40 amp circuit since it is only for a second?
