    200A DC Reversing Contactor Details

    Tips: Differences between AC contactor and DC contactor

    1. Different iron core: The iron core of an AC contactor is laminated by the insulated silicon steel sheets, which is in a double E shape; The iron core of an DC contactor is made from a whole soft iron, which is in a U shape.
    2. Different arc-extinguishing system: The AC contactor mainly adopts a splitter arc-extinguishing while the DC contactor adopts a magnetic quenching device.
    3. Different turns: AC contactor has fewer turns that are connected with the AC while DC contactor has more turns that are connected with DC. On-off of AC contactor is controlled by AC while that of DC contactor is controlled by DC. Highest operation frequency of AC contactor is 600 times per hour, the cost is low; while that of DC contactor could be as high as 2000 times per hour, the cost is high.

    DC Reversing Contactor for DC Motor Forward/Reverse Control
    The reversing type of DC contactor has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks. In this video, ATO will show you how to use a DC reversing contactor for the DC motor forward and reverse control.

    Good price contactor, delivered earlier than expected
    I bought 2 of these 200A  DC reversing contactor, they were delivered earlier than expected. Exact original replacement part for my Toro Mower. Easy to install and works great. I will be using this company for all my Toro Mower replacement parts from now on.

    Would like to buy 50A and 200A DC Reversing Contactors
    We have forwarded the requirement to our purchase team, they will contact you for purchase of ADC50 and ADC200. Do you supply any arrangement for providing isolation between the terminals of the contactor (ADC50 and ADC200)? So that the lugs connected to the terminals never come in contact with each other.

    ATO Responded
    Don't provide isolation protection between terminals. But We recommend to cover your terminals with protective silicone.
