Key Features:
The ABB PSE72-600-70 soft starter is built to control the acceleration of three-phase AC motors, offering a smooth and gradual ramp-up during start-up, which reduces the initial surge of current that can cause electrical damage and excessive mechanical wear. By controlling the motor's voltage during start-up, the PSE72-600-70 prevents damage due to sudden surges and extends the lifetime of the motor and connected systems.
