#1 Scotty you need to relax. Don't let the shroud of internet anonymity get to you head.
#2 As for nice simple explanation that you requested,it is called a Class R fuse. Just do the math, and pick the right one.
Or...If this is not a "code" installation, or if you just don't feel like wasting 40-100$ on a motor starter for a fan that probably cost less than 20...a 5A fuse will be adequate. Fuses aren't resettable, but easily replaced.
