  • Scope of Application

    CJ19 AC Contactor (Also known as magnetic contactor) is mainly used for the power line of AC 50Hz or 60Hz, rated operating voltage of 400V, for putting into low-voltage reactive power compensation equipment into or cutting off low voltage parallel capacitor. The magnetic contactors have inrush current suppression device, magnetic contactor can effectively reduce the impact from closing inrush current for the capacitor and inhibit the over-voltage when making and breaking.

    Model and meaning

    Structure characteristics

    1. CJ19 (CJ16) series magnetic contactor for the direct-acting double-break structure, the contact system is divided into two layers, the upper layer has inrush current suppression device composed of three pairs of current limiting contacts and current limiting resistance, when it closes, work contact connected before it connected for a few milliseconds, the permanent magnet in the current limiting contact releases via spring reaction force, breaks current limiting resistance, so that the capacitor work normally. Internal circuit connection diagram of contactor see Figure.
    2. 12,18,20Kvar magnetic contactors have two pairs of auxiliary contacts, 30Kvar magnetic contactor has three pairs of auxiliary contacts.
    3. Contactor terminals are covered with an insulating cover, safe and reliable. Coil terminals are marked with voltage data to prevent incorrect connections. 12,18,20Kvar magnetic contactor can be installed by screws, but also installed in the 35mm standard card rail of 35mm by the bottom of the slider buckle. There is a removable white rectangular card on the mask that allows the user to print the item code.
