The B30C series contactor is another special contactor for on-off capacitors derived from the B series AC contactor. It is the latest product produced by our factory. Its structure is different from the ordinary switching capacitor contactor. The resistance switching circuit part is on both sides of the main circuit part, and a discharge device is attached. When the capacitor is withdrawn from the power grid, the discharge device is connected to the capacitor, which can make the residual in the capacitor. The voltage drops below 50V within 30s, meeting the requirements of the latest 3C certification standards for low-voltage reactive power compensation devices. Users can save external discharge devices, thereby reducing costs. Its structural design is reasonable and novel, and it is a new type of dedicated switch that is currently vigorously promoted. Capacitor contactor.
