Three-phase motor using three-contactor for inverting circuit
Just as shown in the circuit, the three AC contactors named KMF, KMR and KM are used, which means that each time breaking the motor, the main contact point would grow to four off-points (that is two contacts more than that of the two-contactor). Therefore, it can effectively extinguish the arc of the contactor and can prevent arcing fault.
