I have a three-phase 'smeg'.

We have that particular model because it was literally the only induction cooktop on the market that would fit the existing hole in our stone worktop.

Quite a lot of them can be wired either one, two or three-phase when you look into their installation instructions, it's just that not that many houses have three-phase power and not many people are willing to pay to get that upgraded just for the hob.
