The listed motor ratings are only approximate values. The soft starter should always be
designed on the basis of the motor current (rated operational current). A larger model may
need to be selected for different conditions.
Motor output ratings are based on DIN 42973 (kW) and NEC 96/UL508 (hp).
Design with Simulation Tool for Soft Starters (STS)
For dimensioning soft starters under other supplementary conditions, also for heavy starting
up to CLASS 30, we recommend our Simulation Tool for Soft Starters (STS):
