The SSW7000 standard is designed to withstand a 4,5xIn overload duty for 30s, the SSW7000C standard is
designed to withstand a 4xIn overload duty for 20s.
In order to select the SSW7000 model according to the desired overload duty, see table 9.4 to table 9.12,
which inform the maximum motor starting time for different current levels and different quantities of starts per
hour.
NOTE!
For different overload duties, it is important to take into account the correct sizing of the medium-
voltage fuses.
