3.3 Selection of Soft Starter Size
The size of the soft starter must match the motor and the application.
Select a soft starter that has a current rating at least equal to the motor's full load current rating (see motor nameplate) at the start
duty.
The soft starter's current rating determines the maximum motor size it can be used with. The soft starter's rating depends on the
number of starts per hour, the length and current level of the start, and the amount of time the soft starter is off (not passing cur-
rent) between starts.
The soft starter's current rating is only valid when used in the conditions specified in the AC53 code. The soft starter may have a
higher or lower current rating in different operating conditions.
