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).
What are the Difference Between AC and DC Contactor
Distinct differences in operating principles exist between DC and AC types. DC types use the magnetic field around a coil to manage the contacts. AC types are driven by the magnetic field produced by alternating current. DC contactors utilize a freewheeling diode to dissipate the inductive load built up over the coils when the supply current is
