Got it!!  From the Waytek website:
" The difference between an ATC and an ATO fuse is that an ATC’s fusible
link is sealed or “closed,” and an ATO fuse is “open,” meaning it has a
small opening that exposes the fusible link to the air."

I'd found the same thing on a forum message but wanted a better source
before I'd post it.  And the official designation of the 'Mini' fuse is
ATM, found that a couple of places.

Now can I go watch TV? :)
