100 hp AC motor soft starter, 75 kW three phase 240v, 400v, 480v, 690v for selection, manufacturer direct sale.

Tips: The choice of soft starter capacity
In principle, the soft starter capacity should be greater than the capacity of the motor it drove. The rated capacity of the soft starter usually has two nominal values. One nominal value is according to the corresponding motor power, and the other is according to the allowable maximum operating current of soft starter. Should pay attention to the following two points:

1. According to the motor rated power, then the product of different voltage levels has different rated current. For example, a 100hp (75kW) soft starter, if the voltage level is AC380V, then the rated current is 150A, if the voltage level is AC660V, the rated current is 100A.
2. According to the allowable maximum operating current of soft starter, the product of different voltage levels has different rated capacity. For example, a 160A soft starter, if voltage level is AC380V, the rated capacity is 100hp (75kW), if voltage level is AC660V, the rated capacity is 180hp (132kW).

Also should synthetically consider other factors for selection, such as the soft starter carrying capacity, working system, environmental conditions, cooling conditions and others.
