3C certification composite switch ZFK-30B composite switch 
 3C certification ZFK series of composite switch manufacturer, we provide you with zfk voltage composite switch, high-quality 3C certification composite switch products, composite switch price, composite switch selection, evaluation and other relevant information composite switch, you are welcome to purchase 
 ZFK-30B is the latest generation of composite switch low voltage reactive power compensation capacitor switching device switches, a control of the implementation of environmental protection energy-saving component, composite switch is my company and exchange contacts for silicon in the low voltage reactive compensation for deficiencies that exist in the application of well-developed scientific and technological achievements. 
 ZFK-30B composite switch for low-voltage reactive power compensation capacitor on-off control. Total compensation 30 Kvar / min supplement 10Kvar rated current 45A. Basic working principle is to SCR, and then with magnetic latching relay. The composite switch is turned on and off instantly with SCR switching the advantages of zero, while during the normal turn no power but also has the advantages of the contactor. 
 ZFK-30B composite switch and AC contactor, SCR, or solid state relay components compared to a great technological advantage. The main advantage is the external control signal received by logic, automatically find the best inputs (cut) point; ensure zero switching, no current; contact no sintering; energy consumption; no harmonic injection; both voltage anomaly protection; lack of protection; component failure protection; operating instructions and other functions. Compared with similar products, it is technically extremely advanced, high efficiency and low consumption, environment protection and energy, especially in terms of safety and reliability of surge and significantly better performance.
