The motor outputs listed are only rough values. The dimensioning of the soft starter should always be carried out on the basis of the motor current (rated operating current). A model with a higher
output may be necessary for deviating conditions.
The motor output specifications are based on DIN 42973 (kW) and NEC 96/UL508 (hp).
For optimum dimensioning and/or deviations from the boundary conditions described, we recommend the use of the "Win Soft Starter" selection and simulation program, which can be
