DH20 High Voltage DC Contactor
▇ The design conforms to UL508 safety requirement,main contact is with 20A switching with load capacity&max. switching voltage 900VDC;
▇ Small volume, light weight, seal structure for the main contact,working under inert gas protection, high breaking capacity,with no flash, can work continuously in the hostile environments;
▇ Low coil power consumption, just 3.5W,effectively reduce the control loss, especially beneficial to be used in battery-powered occasions,extend the life of battery;
▇ Flexible installation method and various coil voltage for selection,meet the practical demands maximumly;
▇ With fast and safe connection mode, remarkably improve the installation efficiency and reliability;
▇ All series products get UL508 certificate and comply with RoHS,reliable & environmental protection;

Part Numbering System
1.The key feature of the end of electrical life is that the main contact insulation resistance does not meet the requirements;
2.No rule of the product installation direction , can be installed arbitrarily ;
3.When the product air-leaking or breaking fault current , please replace it immediately;
Outline dimensions
1.The fixed screw should be prepared by customers themselves, we recommend M3 screw to install the product, recommend torque is 0.8~1.3N.m;
2.If you have other special requirements for the accessories, please contact the factory or local office;
