    400A DC Reversing Contactor Details

    Tips: Reasons for the contacts of contactor being unable to separate after powering off

    1. Control line of the coil is too long, the residual voltage is too large due to the influence of lead capacitance, which is enough to maintain a close situation for the iron core. As a result, the contacts can't be separated.
    2. Coil of the contactor has burnt out, deformed coil skeleton seizes the movable iron core, which makes it unable to move, thus the contacts can't be separated.
    3. The contact has been fused.
    4. The contactor has auto-lock function, and the function is normal.

    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.

    Existing reviews of 400A DC Reversing Contactor, 2 pole, 12V/24V/48V
    400A DC reversing contactor worked fine
    The DC reversing contactor worked fine, but after replacing it, my winch still didn't work. Found out it was corroded battery terminals that was causing the problem. Cleaned them up and it worked. Only complaint would be that it is a little pricey.
