Jandy Aqualink Fuse 3A or 3.15A?

So I've had a perfectly functioning Aqualink RS for about 13 years. Last October after Hurricane Matthew made his appearance I noticed that my system was dead. Turned out to be the fuse. My local installer replaced the fuse and it ran fine for a couple of months. Then in early March same thing. Panel dead, replaced the fuse and it worked again.

Finally it went again this week. Had the installer back out, but this time I met him here so he could show me the fuse so at least I could replace it myself next time. So he replaced the fuse and it came back to life. He gave me the package for the replacement fuse so I could buy my own in case this happens again. It's a 5mm x 20mm 3A 250V fuse from Radio Shack.

So I went online looking for a "Aqualink RS fuse", and everything I could find including the following directly from Jandy says it should be a 3.15A fuse, not 3A. Could it be that simple? Anyone have any experience with a fuse blowing frequently but not immediately like this? Thanks.
