Iec 60038 Standard Voltages Pdf 103 【2026】

The IEC 60038 standard, titled "IEC Standard Voltages," is the primary international benchmark for nominal electricity supply voltages across alternating current (AC) and direct current (DC) systems. Published by the International Electrotechnical Commission (IEC), its purpose is to harmonize global electrical infrastructure, ensuring that equipment manufactured in one country is compatible with the power grids of another.  Core Objectives and Scope 

is the primary international standard for electrical supply voltages, providing a universal framework to harmonize power systems and equipment design globally. The current edition (2009, with 2021 amendments) defines standard nominal voltages for AC and DC systems from low to ultra-high voltage.

Conclusion

• Standardization: IEC 60038 provides a standardized framework for voltage levels, ensuring compatibility and interoperability across different power systems.
• Safety: The standard voltages defined in IEC 60038 are designed to ensure safe operation of electrical power systems, minimizing the risk of electrical shocks and other hazards.
• Efficiency: The standard voltages help optimize the efficiency of electrical power systems, reducing energy losses and improving overall system performance.

Similarly, the 103-region notes that 230/400V and 240/415V systems are considered interchangeable for equipment (thanks to tolerances). Similarly, the 103-region notes that 230/400V and 240/415V

• AC voltages from 100V to 1,000V (Low Voltage – LV)
• AC voltages above 1kV up to 765kV (Medium and High Voltage – MV/HV)
• DC voltages from 2.4V to 12kV
