EV Spare Parts New Energy Electric Vehicle High Voltage Fuse DC750--12-60

• Standard: IS0 8820-1, IS0 8820-8, JASO D622

• Rated voltage: DC750V

• Rated current: 12A, 16A, 20A, 25A, 30A, 40A, 50A, 60A

• Breaking capacity: 5kA

• Protection object: Provide safer and more reliable protection against overload and short-circuit current faults of electric vehicle lithium battery pack, Super-capacitor circuit , charging circuit, DC-DC converter and other devices.

• Applicable environment: Temperature from -35℃ to 85℃, humidity ≤90%.

• Material description: 95 alumina high strength ceramics and imported material fuse piece.

• Structure process: copper metal is riveted after welding process; The internal quartz sand is processed by solidification to prevent products from falling off in dynamic working conditions and prevent arc spraying which is caused by line faults.
