How to choose suitable PV Accessories?
PV Accessories are auxiliary components in photovoltaic power generation systems, which are of great significance to ensure the efficient operation, stability and safety of the system. Common photovol
• Standard: IS0 8820-1, IS0 8820-8, JASO D622
• Rated voltage: DC500V
• Rated current: 200A, 250A, 300A, 350A, 400A
• Breaking capacity: 20kA
• 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.
