Description: a specific design within the context of a type, which is generally characterized by its dimensions. A construction can comprise several design (variants), which generally vary in terms of mechanical details; Name: Construction of the transmission
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
