    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: Types of Contactor Auxiliary Contacts

    • The main contact, mostly normally open contacts, has a large current carrying capacity, and is mostly used to control motor startup and other controls.
    • Auxiliary normally open contacts, play an auxiliary role, can be used for self-locking, signal transmission and other circuit requirements.
    • Auxiliary normally closed contacts, to achieve linkage in complex circuits, sometimes used as motor interlock.
