    Tips: The contactor coil is overheated or burned down

    Possible causes of the fault:

    • Supply voltage is too high.
    • Contactor is frequently operated.
    • High ambient temperature, end face of the contactor's iron core is not smooth.
    • There's a mechanical failure on the contactor's movable iron core, which makes the iron core unable to suck, turn-to-turn short circuit.

    Maintenance method:

    1. Measure whether the working voltage on the contactor conforms to the rated voltage of the contactor coil, if it's too high or too low, adjust it to the normal voltage value.
    2. Improve the temperature of working environment, strengthen heat dissipation.
    3. Clean and wipe the end face of contactor iron core, replace the iron core when necessary.
    4. Check if the mechanical part of the contactor moves flexibly, replace a same type coil after repairing if the coil has been burned out.
    5. Eliminate the reasons for causing mechanical damage of the contactor coil, replace the coil.
    Existing reviews of 80A DC Contactor, single pole, 12V/24V/48V
    Contactor worked great
    I ordered two of these contactors for a project and they both worked great. Thanks for quick delivery and I would buy again from the same vendor.
