The NJR5-ZX series soft starter is an online motor starter supporting AC220V-690V input voltage with a 15A-1000A current range. Utilizing power electronics and microprocessor control, it precisely regulates thyristors to enable smooth soft start/stop for three-phase asynchronous motors. This solution eliminates inrush current while providing optimal torque control, making it ideal for fans, pumps, compressors, and crushers in demanding industries like metallurgy, mining, water supply, and petrochemical.
Compliant with IEC 60947-4-2, NJR5-ZX offers superior reliability and load adaptability as a modern replacement for star-delta starters and auto-transformer systems.
