Low voltage


Where two voltages are given below separated by “/”, the first is the root-mean-square voltage between a phase and the neutral connector, whereas the second is the corresponding root-mean-square voltage between two phases. The three-phase voltages are for use in either four-wire (with neutral) or three-wire (without neutral) systems.

Three-phase 50 Hz


  • 230 V / 400 V
  • 400 V / 690 V
  • 1000 V


Suppliers using 220 V / 380 V or 240 V / 415 V systems were expected by the standard to migrate to the recommended value of 230 V / 400 V by the year 2003. This migration has already been largely completed, as least within the European Union.

Three-phase 60 Hz

  • 120 V / 208 V
  • 240 V
  • 277 V / 480 V
  • 480 V
  • 347 V / 600 V
  • 600 V
