Tips: Working Principle of the Contactor

When the contactor coil is energized, the coil current will generate a magnetic field. The generated magnetic field causes the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the AC contactor point to move. The normally closed contact is disconnected and the normally open contact is closed. The two are linked. When the coil is de-energized, the electromagnetic attraction force disappears, and the armature is released under the action of the released spring so that the contact is restored, the normally open contact is disconnected, and the normally closed contact is closed.
