NanJing QuanNing Electric Co., Ltd.
QNE500A High Voltage DC Contactor
QNE500A High Voltage Dc Contactor is used for auxiliary electrical switching control of electric vehicle, precharge control, electric vehicle, fast charging pile, battery switching and high voltage DC voltage switching control of electric motorcycle, circuit protection and safety control, etc.
500A+ charging capacity, can rupture 2000A current at 320VDC; Small size, light weight.
The switch part and the driving part are inflated and sealed to cut off the high-capacity load.
Fully sealed structure, high safety; Non-oxidation coils and contacts can be used in explosive or harmful environments, even for a long time;.
Product standard:IEC60947-4， GB14048.4
Certification: CE
