Self resetting fuse for charge controller

I am wondering if anyone has used self actuating or self resetting breakers for the positive line from charge controller? Any downside to using these instead of manually resetable breakers?

It always has a reason for a breaker to break or a fuse to blow.
Under normal conditions a fuse should never blow, so it should never be necessary to use a self resetting fuse/breaker.
If a fuse blows constantly you should look for the reason instead of using a bigger fuse or
self resetting fuse.

Thank you for the response. I am asking what the pros and cons of using this type breaker like this are.

Pro: you can reset it if it trips, what never should happen under normal circumstances

Con: it's much more expensive than a simple blade fuse
