NJR2-T series soft-starter is suitable for three-phase 220V voltage level soft starter, and 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.
The products form into complete set mainly with control cabinet; and are mainly used supporting the bypass AC contactor with corresponding specifications. The product specifications cover 7.5KW ~160KW squirrel cage type three-phase AC induction motor; and 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.
Standard: GB 14048.6 IEC 60947-4-2.
