Ultrahög spänningstolerans och bred strömanpassningsbarhet
The product has a rated voltage of 1000Vdc (direct current) and 500Vac (alternating current), and a current range of 500mA to 40A, which is suitable for high-voltage scenarios. Its breaking capacity is 50kA@1000Vdc (100mA-32A model), and some models can even reach 150kA, ensuring that fault currents are quickly cut off in photovoltaic, energy storage and other systems. For example, at a voltage of 1000Vdc, when the overload current is 200% (such as a 50A fuse with 100A), the fusing time is only 120 seconds, preventing the equipment from overheating or catching fire. This feature stems from the combined design of its ceramic tube body (withstands voltage>=1500V) och ren silversmälta (hög smälteffektivitet), säkerställa stabilitet under högspänningsmiljöer .

Högintensiva brytning och exakta svaregenskaper
The breaking capacity of the fuse is dynamically adjusted according to the current level: 150kA@500V (100mA-32A), 80kA@690V and 50kA@1000V, meeting the needs of different voltage levels. Its electrical characteristics show that the fusing time is>=4 hours at 110% of the rated current,<=1 hour at 135%, and<=120 seconds at 200%. For example, in a 25A fuse, it will be blown within 120 seconds at an overload current of 50A, and the response speed is 30% faster than that of traditional products. This feature is derived from arc-extinguishing filling technology (arc suppression) and melt geometry optimization (accelerated fusing), ensuring rapid fault frånkoppling .

Kompakt struktur och effektiv installationskompatibilitet
The product adopts a 10x38mm cylindrical design, which is suitable for bolt fixing, PCB installation and other forms. Its ceramic tube body has a diameter of 10mm and a length of 38mm, which is 20% smaller than traditional fuses. It also supports 6N·m torque installation to ensure connection stability. For example, in a photovoltaic junction box, the compact design can reduce the space occupied by cables by 30%, and adapt to automated production lines through single-ended/double-ended PCB pin options. This feature is due to high-strength ceramic materials (resistant to mechanical shock) and standardized end cap design (compatible with international standards).

Miljööverensstämmelse och verifiering av långvarig tillförlitlighet
The product complies with RoHS and REACH regulations, uses lead-free nickel plating and recyclable ceramic materials to reduce environmental impact. Its 20kA@1000Vdc repeated disconnection test shows that the performance degradation is<=5% after 5000 cycles, and the life is extended by 30% compared with traditional products. For example, at a rated current of 25A, the power consumption is only 500MW, som är 15% lägre än liknande produkter . Denna funktion beror på det höga renhetsmältmaterialet (låg resistivitet) och den optimerade termiska motståndsdesignen (hög värmefördissionseffektivitet), vilket säkerställer långvarig stabilitet .}
