Review on GLOSO E39 Manual (T3) Reset Low Profile ATC/ATO Circuit Breakers (6A - 25 Pack) by Lance Foster

I used this to protect a boost/buck converter (and subsequent electronics) in a battery box I built. It hasn't worked yet, but I've been trying to throw no more than 6 amps, so it makes sense. I was about to use a fuse but fuses of this shape are never 6 amps, you have to use round glass fuses which I didn't want to do. The converter is rated at 6 amps, so it's either that or the glass fuses. I'm happy with that, if it works I just push the button. Note that this may not be appropriate for some locations. it is almost twice the size of a conventional fuse in this form factor.
