Working on my Einhell MTB 3000 mini lathe

Hi Stefan.
I have a similar set up to you, as you know...... And use a 5a fuse, with no problems !  :thumbup:

You will certainly notice the increase in pulling power, when you have this all assembled!  :bugeye:

That's what I would do for a motor load.
 
As a rough 'rule of thumb' work out nominal amperage, add 30%, and call it a 'Slo-Blo'.
 
In your case
 
450W / 180V = 2.5A nominal.
 
Multiply by 1.3 = 3.25A Slo-Blo.
 
You ain't a mile away at 3.15A...  :thumbup:
