A voltage used in the designation of the fuse-base or fuse-link, from which the test conditions are determined.
The rated voltage of a fuse and should be selected from the following table:


Notes:

• This rated voltage represents the highest voltage for the equipment,
• On three-phase solidly earthed systems, fuses may only be used provided that the highest system voltage is less than or equal to their rated voltage.
• On single phase or non-solidly earthed systems, fuses may only be used provided that the highest system voltage is less than or equal to 87 % of their rated voltage, unless specific testing has been performed
