CJX2-K series AC contactors are suitable for circuits and frequent starting speeds to control AC motors. Increase the auxiliary contact group of the contactor, live with a suitable thermal relay, and can take action to protect the circuit from overload. It complies with IEC60947-4-1

AC contactors often use three arc extinguishing methods: double-fault electric arc extinguishing, longitudinal slit arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process. Contactors with a capacity above 10A have arc extinguishing devices. The AC contactor also has auxiliary components such as reaction spring, buffer spring, contact pressure spring, transmission mechanism, base and terminal.

The working principle of the AC contactor is to use the electromagnetic force and the spring force to cooperate to realize the connection and disconnection of the contacts. The AC contactor has two working states: power-off state (release state) and energized state (action state). The electromagnetic attraction disappears, the armature is reopening, so that the normally open contact is closed, and released under the action of the position spring, all the contacts are reset accordingly, and the contactor is in a power-off state.AC contactors3 AC contactors4
