              This relay typical application:
              ◆主要用于電動汽車 / 直流充電樁 作切換電流作用;
              Mainly used for electric vehicle /DCcharging pilefor switching current.
              Remarks: Customers need other rated voltage canbe customized.
              Small and lightweight:Internally adopt reliable sealing technology and filled with hydrogen which arc colling ability is high. It can cut off high voltage DC in a short time.
              High contact reliability:Due to the contact sealed in the hydrogen therefore it will be not oxidized also achieving the contact of the dustproof and waterproof.
              Safety and reliable:Use the professional explosion-proof structure designto achieve a high degree of securityadopt magnetic quenching helps to cut-off the DC load quickly.
              Application:DC charging pile electric vehicles hybrid vehicles battery charging and discharging systemPhotovoltaic power generation system such as dc high voltage application.
