What is the 400 volts system?

The 400 volts system is a three-phase electrical power system commonly used in industrial and commercial settings for efficient energy distribution. It typically refers to a three-phase supply with a voltage level of 400 volts between the phases, often encountered in Europe and other regions. This system allows for the operation of heavy machinery and equipment, providing a balance between power capacity and safety. It is also used for lighting and heating applications in various facilities.
