B series AC contactor for AC50Hz or 60Hz circuit for remote making and breaking power lines or frequent control of AC motor. 
 With T series thermal overload relay or the composition of MSB equipped with magnetic starter, can protect the motor overload and phase failure. 
 B25C, B30C, B50C, B63C, B75C switched capacitors are suitable for AC 50Hz, rated voltage 380V compensation circuit making and breaking power capacitors, 
 To adjust the power system power factor, inrush inhibit the ability of the contactor, so that the peak inrush current when connected to rated current of not more than 20 times the working conditions for contacts with the B series of the same.
