If you have 3 phase panel you could pull a 3rd hot wire and a 3 pole / 3 phase circuit breaker and wire it for 3 phase.
Many machines and transformer's are designed to work with various wiring configurations.

That's how North American works. Euro is the same as our 120v but the hot leg is 230v, not 240v shown across two legs of 120v. Their 230v requires a neutral whereas technically ours doesn't.
