Realizing　no-arc　control　in　closing　and　breaking　courses　is　one　of　the　most　important　means　for　AC　contactor　to　improve　the　operation　reliability.　In　recent　years,　no-arc　control　technology　studies　have　been　carried　out　widely　for　AC　contactor.　In　this　paper,　introduce　a　type　of　intelligent　hybrid　AC　contactor　based　on　magnetic　latching　relay.　The　contactor　has　good　cost　performance　ratio　and　high　operational　reliability.　The　new　contactor　employs　three　magnetic　latching　relays,　and　the　control　is　agility.　The　contact　system　connected　with　only　two　unidirectional　SCRS　component　in　parallel.　Realizes　the　no-arc　closing　and　breaking　in　three　phase　circuits.　Every　performance　index　of　the　contactor　has　been　increased.
