Note: For Trip class 20 applications we recommend the use of an external overload protection due to the
higher FLC setting that is required on RSWT. The FLC setting for Class 20 applications needs to be set to a
higher value with respect to the motor FLC in order not to trip the electronic motor overload protection available
on the RSWT soft starters.
