    • DC 12-900V rated load voltage of contact circuit.
    • normally open type (SPST-NO), 12 volt, 24 volt coil for selection.
    • Main contact voltage drop at 100A, not above 100mV.
    • The connection of contact and coil need to be nonpolarity.
    • Efficient coil, retentive power is only 2-2.3W, counter electromotive force is 0V.
    • The joint way of the coil is very convenient.
    • The coil has no counter force of electromagnetism.
    • Compare to the similar products, this product is smallest and lightest.

    100A High Voltage DC Contactor Details

    Tips: Contacts of DC contactor
    In the selection of a DC contactor, control method of the application circuit shall be considered firstly, as well as the role of the contactor in the circuit, because the main contact of DC contactor includes two types of single and double. Single contact contactor is mainly used in electric system, or other independent variable current systems, its functions are: 1 Ready to run; 2 Quickly cut off main circuit in case of accident state. Therefore, the rated current, rated voltage and arc breaking capacity of the contactor must meet the system requirements. Double contacts contactor is mainly used for non independent power supply system or bilateral system, pay attention to the rated current, rated voltage and arc breaking capacity. Finally, the coil suction voltage shall comply with the requirements of operating system. When the suction coil is large, add RC absorption loop to prevent the self-inducing potential to break through itself or relevant equipment.
