■ FEATURES
·400A Contact switch capacity,Small volume；
·A set of bridge type N.O.contacts;contact circuit has "+", "-" polarity；
·Coil with energy saving device,the max holding power consumption is 4.5W.
·Using ceramic brazing technology,the contact part is sealed with hydrogen gas,so it wouldn’t be oxidized,can quickly cut off the dc high voltage;
·Application:Telecom equipment、Solar system、 Engineering machinery、Electromobile、Electric vehicle、Charging system、Train、Ships、UPS etc.;
