ISO IEC 60038

The international standard IEC 60038 defines a set of network voltages from the low voltage range for use in power supply systems . The standard is published in Germany as DIN standard DIN EN 60038 CENELEC standard voltages (IEC 60038: 2009, modified) . A list of the worldwide use of different mains voltages is summarized under country overview of plug types, mains voltages and frequencies .

Low voltage

Where two voltages are indicated in the following, separated by “/”, the first is that between an outer conductor and the neutral conductor , while the second is that between two outer conductors. The effective value is given in each case . For three-phase AC systems a neutral conductor can be carried or not. The relationship between the two voltage specifications is determined by the chaining factor .

Three-phase alternating current, 50 Hz

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

According to the standard, utilities working with 220 V / 380 V or 240 V / 415 V should have switched to the recommended 230 V / 400 V by 2003. This switch was made in the European Union.

Three-phase alternating current, 60 Hz

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

Single-phase three-wire network, 60 Hz

The following voltages are specified in the single-phase three-wire network :

  • 120 V / 240 V
