Rated voltage

Rated voltage

Corresponds to the electrical voltage during normal operation.The nominal voltage is specified as the rated voltage and referenced in most cases to an IEC standard, which is referenced as a test basis for the operating parameters.
The nominal voltage is called depending on the operating condition, with AC voltage it is indicated VAC, and in the case of DC voltage as VDC.

up to 600 VDC
