Description: the electric voltage is the potential difference between two points in the electric field. It is the driving force for the charge movement.; Name: mains voltage
Description: Measured actual mains voltage; Name: Voltage
Description: voltage which, together with the rated operating current, determines the use of the device and to which the various tests and the use categories refer. With single pole devices the rated rated operating voltage is generally the voltage over the pole. With multi-pole devices it is generally given as chained voltage; Name: Operating voltage
