NJR2-ZX Series on-line soft-starter is cored on advanced dual-CPU control technology. It controls SCR  module, realizes soft starting & stopping of three-phase AC induction motor (squirrel cage type), and has wide range of protection functions e.g. overload, input phase failure, output phase failure, load short-circuit, starting limiting overtime, over-voltage, and under-voltage. 

After starting motor, the product does not require bypass contactor, with power specifications covering 7.5KW ~75KW; widely used in electrical drive equipment in the fields of metallurgy, fire, mining, water supply, municipal administration, food,cement and petrochemical. It is an ideal updated product of traditional star - delta starter, and self-coupling voltage starting.
