Lighting Contactor Wiring Test: Demonstrating Operation
A lighting contactor is an electrical device used to control the operation of lighting systems, typically in commercial or industrial settings. It is designed to handle the high current demands of lighting circuits and provide a convenient way to switch multiple lighting loads on and off. The video will conduct a wiring test of the lighting contactor to demonstrate its operational principles.
Note: In the case of contactor mounting in an enclosure for which the interior temperature is in range between 50℃ and 60°℃, it is necessary to use a spacer, between each contactor.

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.
