Selection Notes
● Fully understand the characteristics and usage of the load;
● The soft starter size should always be larger than the motor
current value (rated operating current). In case of deviation from
the rated value, it is necessary to select a larger soft starter;
● Installation altitude: no more than 1000m, above 1000m, consider
capacity reduction.
