Xpk series frequency sensitive starting control box is suitable for starting, stopping and running control of three-phase wound type asynchronous motor with AC 50 Hz, voltage 380 V, current 600 a and below. It is used in places where frequent operation, irreversibility, speed regulation and braking are not required.
 
A frequency sensitive rheostat is connected in the rotor circuit during starting. The impedance value decreases automatically with the increase of motor speed, that is, the decrease of rotor current frequency, so as to achieve the effect of limiting starting current and ensuring torque. The influence of motor starting process on transmission line is improved. It has many kinds of protection, such as overload, over-current and lack of protection.

It can automatically complete the starting process of the motor;
 
During the starting process of the motor, the stator current shall not exceed 2.5 times of the rated current;
 
Starting from cold state, it is allowed to start three times continuously, but the total time shall not exceed 80s, and the time interval between two times shall be greater than 30s;
 
If the total starting time has reached 80s, the cooling time of the product should be more than four hours before starting again to prevent damage to the frequency sensitive rheostat or other electrical components;
