C.R.I. Soft Starter is designed to reduce the torque applied to electric motors during startup. It utilizes solid-state devices such as thyristors to control the supply voltage, enabling smooth and controlled motor acceleration.

The starter operates on the principle that motor torque is proportional to the square of the starting current, which is directly related to the applied voltage. By reducing voltage during startup, both torque and current are effectively controlled.

This soft starter for three-phase motors eliminates high inrush current and excessive mechanical stress during startup. It helps reduce cable and switchgear ratings, prevents voltage dips in the power supply network, and provides smooth, stepless acceleration and deceleration.
