WebSingle phase is a phase related to the neutral. In Belgium that's 230V. But when you have three phases you can use them in relationship with the other phases, and then the voltage between phases is 400V (230V × 3 ). Even at three phase you can use the 230V. You'll have 3 times the power available. That's called a star configuration.
