Contactor working principle

When the coil is energized, the static iron core produces electromagnetic attraction, which makes the moving iron core attracted, which in turn drives the three moving contactor pieces of the contact system to act, the main contact is closed, the auxiliary normally closed contact is disconnected, and the auxiliary normally open contact The point is closed and the power is turned on.

When the coil is de-energized, the electromagnetic attraction of the static iron core disappears, the reaction force of the spring separates the moving iron core from the static iron core, and the three moving contacts of the contact system act to make the main contact open and the auxiliary normally closed contact Closed, the auxiliary normally open contact is opened and the power supply is cut off.
