QJX3 Serise Star-Delta Starters,Cabinet mainly be applicable to the circuit of voltage 440V,AC 50/60Hz. It is used for controlling the 3-phase squirrel-close type induction motor with a power of less than 45kW on AC-3. The startup mode is automarically changed from "Y" to "△". It can protect the motor from overload, open phase, and short circuit. It is widely used in compressors, fans, water pumps and other industrial equipment.
Type and Signification：
Note:When placing an order,please note that the ammeter and voltmeter are configured with pointer type or digital display type

The inductive load will generate a back-EMF voltage at the monment the power is turned on.The peak value of this voltage is far greater than the voltage that the load AC power supply can withstand,so it is easy to cause the instantaneous overload of the star-delta starter cabinet,which will affect the service life of the star-delta starter cabinet.
Therefore,the required star-delta starter cabinet needs to be amplified by one gear.
For example,a 15KW motor needs a 18.5KW star-delta starter cabinet,and a 18.5 motor needs a 22KW star-delta starter cabinet.
