The energy companies are happy if you use more power. So in europe the acceptable voltage is between 180 and 240 volts. Mostly you get the 240 because the used energy depends from the square of the voltage and so you pay more to the companies. :-(
for 3 phases you have then 240 * 1.732 = 415 volts ...
