NJR2-D soft starter utilizes advanced dual-CPU control technology to regulate SCR modules, providing smooth soft start/stop functions for three-phase AC induction motors (7.5KW - 500KW, 380V). This robust solution features comprehensive protection against overload, phase failure, short-circuit, and voltage irregularities while requiring an external bypass contactor.
With excellent load adaptability and proven reliability, it's widely applied in demanding industries including metallurgy, mining, water supply, and petrochemical. Compliant with GB 14048.6 and IEC 60947-4-2 standards, the NJR2-D series represents a superior alternative to conventional star-delta starters and auto-transformer starting methods.
