100A High Voltage DC Contactor Specifications
100A DC Contactor Installation DiagramHigh Voltage DC Contactor Coil SchematicTips: Contacts of DC contactorIn 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.
