Choosing Between DC and AC Contactors | BENY New Energy. Both AC and DC contactors can be distinguished based on the number of coils. The DC contactor has more coils than the AC contactor, which has fewer coils. Two-phase winding coils should be used in series by the contactor if the primary loop current is too high (i.e., greater than 250A).
The DC contactors are used widely in Energy Storage Systems (ESS), along with the other applications such as: electric vehicles, car charging, etc. After reading this article, you will have a better understanding regarding the basics of Energy Storage Systems and the connection of the ESS with the contactors using a battery.
