General
CJ19i contactor for capacitor switching (hereinafter called contactor)is suitable forthe circuitofAC 50Hz/60Hz with rated rated voltage up to 690V.It is mainly used toadd low voltage reactive power compensation equipment or cut off low voltageparalel capacitor.The contactor is equipped with a device to suppress the inrushcurrent,which can effectively reduce the impact ofthe making inrush current on thecapacitor andsuppress the over-voltage when thecapacitor is cut off.Standard:IEC/EN 60947-4-1.

The YCQD7 series intelligent integrated star-delta starter (hereinafter referred to as the starter) is suitable for three-phase squirrel-cage asynchronous motors with an AC frequency of 50Hz, a rated voltage of 380V/400V, a rated operating current of up to 110A (phase current when the starter is in delta connection), and a control power of up to 90kW. It is used to control the starting, running, and stopping of three-phase squirrel-cage asynchronous motors with a stator winding connection changed from star to delta, thereby reducing the starting current and the impact of motor starting on the transmission network.

The starter adopts modular design and integrated structure, integrating contactor, intelligent controller and auxiliary contactor. The intelligent controller can automatically control the starter operation according to the predetermined program to complete the star-delta starting of the motor.

CJX2s series AC Contactor with novel appearance and compact structure is suitablefor using starting &controlling the AC motor frequently,switching on and off thecircuitat a long distance.It is used in combinationwith thermal relay to compose amagneticmotor starter
