CR2 series intelligent motor soft starter is mainly used for starting, running and stopping control and protection of squirrelcage motor. Because when the motor starts directly, the starting current can be as high as 7~10 times the rated current ofthe motor, the impact on the power grid is larger, and will affect the life of mechanical equipment, and even cause seriousfailures, bring about significant economic losses. The use of CR2 series intelligent motor soft actuator can avoid theseproblems.In addition to the general functions of ordinary soft starter, it also increases the current adjustable function, intelligent monitoring and protection, communication function, so that the product has a wider range of applications, canbe widely used in metallurgy, chemical industry, construction, mining and other protection requirements, high degree ofautomation occasions.
