Why DC Contactor Work Well under High Power Supply Condition?

Strong arcing generated when switch disconnected,which can't be handled by common relay .To make sure system work functionally, we need to cool down it quickly . Strong arc-extinguishing capability is a basic feature of high voltage DC contactor .It also have good impact resistance and anti-blocking capabilities ,to avoid adhesion or relay damage.That's why we have to use sealed magnetic contactor .

For a sealed magnetic DC contactor, hydrogen is important ,which helps to cool down arcing quickly so that high voltage loading can be instantly shut off .  

Picture for reference below .

High voltage DC contactors are widely used in electric elehicle, charging system, battery energy storage system,solar system, golf gar, fuel cell vehicle, etc.,please conact with me for complete solution offer .
