QJ3 Self coupling voltage reducing starterDetailed product description：

The QJ3 autotransformer voltage reducing starter is suitable for infrequent voltage reduction starting and stopping of three-phase squirrel cage induction motors with AC 50Hz, voltage 380V, and power of 10, 14, 28, 40, 55, 75, and 100KW for general industrial use.

The QJ3 autotransformer voltage reducing starter is suitable for general industrial AC 50 or 60 Hz, voltage from 220 V to 440 V, and power up to 75 kW three-phase squirrel induction motors for infrequent low voltage starting and stopping. It uses an autotransformer for compensation during starting and is equipped with overload and voltage loss protection devices.

Main technical parameters
The QJ3 autotransformer voltage reducing starter is classified based on the rated voltage and rated power of the motor, combined with the selected rated current of its contacts and the autotransformer equipment used for starting. The data is shown in Table 2 (excluding rated working and thermal protection setting currents in the table, unless otherwise required).
