thanks a lot for so detailed shares. The DC contactor are meeting more and more critical and harsh working conditions, it not only has to work under high voltage to very well break HV electrical arc, but also has to very well handle the heavy inrush impact. Acted as a senior engineer for tens years of experience, I also often to help user to sove such problem and failures. I would like to exchange insights how to very well solve the problem and how to design a DC contactor to avoid such failures. By the way, in fact, there are so many kind of DC contactors, it is very important to choose the suitable one while making product selection.Thanks for all the sharing people, it make us, make technology going forward.Thanks.
