The invention relates to an arc-free alternating current contactor with disconnecting gaps and belongs to the field of contactors. The device comprises a lower shell, a middle shell, an upper shell, an upper end cover, a first electromagnetic operating mechanism, a second electromagnetic operating mechanism, a silicon controlled rectifier module and a control circuit board. The arc-free alternating current contactor with the disconnecting gaps is just the same as a conventional alternating current contact in using method and appearance, and the arc-free alternating current contactor with the disconnecting gaps is convenient to replace and has the function of arc-free connection and disconnection. The electrical endurance of the contactor is greatly enhanced, the manufacturing of contacts made of special material is canceled, and electromagnetic interference and fire hazards caused by arcs generated by connection and disconnection are avoided. After the contactor is disconnected, a power supply side and a load side are provided with the obvious disconnecting gaps, and electrical isolation is reliably achieved.
