JW is correct that fuses will blow quicker than Breakers of the same size.
I do believe fuses are safer. But keeping spares is a smart thing to do.
Most home style breakers contain a heating element and a bimetallic Cutout, Heat makes them open.
The breaker may take a dead short or UP TO 10X rated Value to trip Immediately.
The surge current of normally operating devices (Mostly Motors) is the reason that breakers have delays built in.
Normally they will trip at there rated current in Milliseconds (MS). Could be many, depending on the load.
If it was very many seconds, the Fire could have already started, and that would defeat its purpose.
I disagree with that link as it states.
"A fuse might make the difference if you get hit with lightning."
I Fuse can not protect from a direct hit from lightning. It will jump across it.
A gas discharge tube connected to a good ground maybe, but not a fuse of any type can fool Mother Nature.
Making sure the current flows into the ground, instead of your equipment is the key.
