What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• Standard: IS0 8820-1, IS0 8820-8, JASO D622
• Rated voltage: DC500V
• Rated current: 50A, 60A, 70A, 80A, 100A, 125A, 150A
• 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.
