A .22lr fits in some 3AG fuse holders. They do produce an audible alert when they blow. I'm not sure what the current rating is though.
I'm guessing it's well above 3 amps.
3AG is just the physical size of the fuse, they usually go up to 20 amps from memory.
Well i figure at least till a Dead short.
