    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: What is the Lighting Contactor?

    The lighting contactor is a relay switch that controls the flow of current through a circuit that supplies power to the lighting in a given area. They exist remotely and control circuits with higher voltages. If they are directly controlled, they may cause danger to the operator. The lighting contactor switch operates under a lower but safer load and uses an electromagnet to control the high voltage/current circuit.
