Slow Blow Fuses

[Kilowatt]

I have a UPS that had a 5A fuse. The only replacement I have found is a 5A
slow blow. I am guessing the slow blow is much better than using aluminum
foil but how close is it to a regular fuse?

As the other poster indicated, the slo blow will not protect electronics
very well.

That said, the odds are that when you put in the "proper" fuse it will still
fail.

Unless you can link a fuse failure to something YOU DID than the fuse blew
because of an internal failure. Sometimes fues just blow but it just
doesn't happen very often.
