Function and Application
The NQ1 series intelligent integrated star-delta starter (hereinafter referred to as the starter) is suitable for three-phase squirrel-cage induction motors with an AC frequency of 50Hz, rated voltage of 380V/400V, and maximum rated operating current of 265A (phase current when the starter is connected in delta), controlling power up to 185kW, for starting, running, and stopping by switching the stator winding from star to delta, thus reducing starting current and the impact of motor starting on the power supply network.
