I am building a bluetooth based home automation system using Arduino nano and MOC3041 and BTA16.
Thats all the components majorly.
At the final stages I was thinking about increasing the safety by adding a fuse and I came across this.
I just want to know whether they are durable and robust enough to be used.
Also there are a lot of amperages to choose from.
How to decide for that.
Thanks.
Chose an amperage that is a little higher than the maximum current of the properly operating circuit.
They work fine; that's a perfectly appropriate use of them.

They work well enough.
If you are fusing a load that is known, it's best to fuse it a little above the working draw. If the load is not known, fuse it a safe margin below the absolute maximum rating for the supply,
Also available in tiny smt packages. Your Arduino has a 500ma polyfuse on it. (Probably)
The closer to the trip value current the longer it will take to trip. In extreme cases it can take an hour. While they will recover each time they blow they deteriorate. I would recommend replacing them if you blow them about ten times.
