High Voltage DC Contactor Coil Schematic
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.
The CHN-ADH100 contactor is specially design to meet the requirements of high voltage DC switching applications. Available with 12V or 24V coils, SPST-NO contact form, 100A rated load current of contact circuit, DC 12-900V rated load voltage.
