	What kind of Contactors are used in DC Fast charging Stations? I believe we need utilization category of DC-13 for DC Fast charging I have seen companies using DC-1 utilization for the same. Some of the manufacturers using DC-1 are Dongya, TE, Little Fuse. is this okay for DC switching? Assuming 16 closing and opening Contactor operation in a day with current as much as 100A, 125VDC is this a valid option for using DC-1 utilization instead of DC-13. anyone here knows which company claims or documents contactors with DC-13 utilization factor? Generally i see these in Aux contacts of contactors and not on the Main contacts. Any Opinions on this one? Kindly share with some technical details
