■ 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 hold in power consumption is 4.5W.
·Using ceramic brazing technology,the contact part is sealed with hydrogen gas.The contact does not oxidize,can quickly cut off in the dc high voltage;
·Application:Telecom equipment、Solar system、Engineering machinery、Electromobile、Electric vehicle、Charging system、Train、Ships、UPS etc.;
