■ FEATURES
500A Contact switch capacity ,small volume;
A set of bridge type N.O. contacts, non-polarity of main contact circuit；Max switching voltage 1500V;
Using ceramic brazing technology, the contact part is sealed design with hydrogen gas, the contact would not oxidize, can quickly switch off the dc high voltage;
Application：Energy storage systems、Electric vehicle、Charging system、UPS etc.；Certificate：CE（IEC60947-4-1）、UL（UL60947-4-1）
