If you are looking for specific IEC 60038 standard voltage tables , it is crucial to recognize that the international trend is toward harmonizing on 230/400 V for low-voltage systems to simplify international equipment design. Always check the latest 2009/2010 amendment for the most up-to-date regional exceptions.
The standard sets the universal three-phase four-wire system at 230 V / 400 V . This transition effectively replaced old regional standards like 220V/380V and 240V/415V.
), the first is the single-phase voltage (phase-to-neutral) and the second is the three-phase voltage (phase-to-phase). : The primary standard global ranking is . This value replaced the older
However, the publication explicitly does not apply to voltages representing or transmitting signals, nor does it apply to voltages of components within electrical devices.
: The minimum operating voltage under normal conditions, excluding temporary drops or faults. Core Voltage Classifications in IEC 60038
Covers voltages above 230 kV up to 1,200 kV (e.g., 400 kV, 500 kV, 765 kV).
