The　zero-current-break　control　is　a　core　technique　in　new-type　intelligent　AC　contactor.　To　realize　the　zero-current-break　control,　the　contactor　not　only　needs　accurate　signal,　strict　computer　control　program,　consistent　operation　time,　but　also　particular　contact　structure　to　cooperate　with.　The　zero-current-break　control　technique　makes　the　contact　structure　of　the　AC　contactor　be　different　from　the　traditional　contactor.　In　the　paper　the　finite　element　software　of　the　three-dimensional　electromagnetic　field　is　used　to　analyze　the　contact　system　of　intelligent　AC　contactor,　in　order　to　find　out　more　suitable　contact　system　of　the　intelligent　AC　contactor.
