Fuse DC Solutions: High-Breaking Capacity Protection

Our Fuse DC products are meticulously engineered to excel in DC environments, addressing the unique challenges of interrupting direct current. The foundational aspect is the high breaking capacity of up to 100kA, enabling the fuse to safely open during short circuits without exploding or causing secondary failures. This is crucial in photovoltaic systems where high short-circuit currents can exceed 50kA. By limiting the let-through energy to minimal values, our fuses reduce the thermal and mechanical stress on downstream components, prolonging their lifespan. For instance, a major player in the Chinese PV industry adopted our fuses in a 1 GW installation and reported a 30% reduction in equipment damage due to less stress. The design includes an optimized arc-extinguishing structure that rapidly cools and extinguishes arcs, ensuring fast interruption times in under 1 millisecond. Advanced automated optical scanners monitor every production lot to guarantee absolute structural integrity

In the international marketplace, having the right certifications is non-negotiable. Our Fuse DC products are certified to major global standards, ensuring seamless integration into any project. We hold IEC 60269-6 certification for gPV fuses, which is mandatory for photovoltaic applications in Europe and many other regions. Additionally, our products meet UL 248-19 requirements, allowing us to serve the North American market with confidence. We also maintain CE marking, CCC for China, and ISO 9001:2015 for quality management. These certifications are not merely paperwork; they involve regular audits and type testing at internationally accredited laboratories. For instance, our fuses successfully completed testing at DEKRA in Germany and UL in the USA, confirming their electrical, thermal, and mechanical robustness. Rigorous external laboratory evaluations ensure compliance with evolving international regulatory frameworks across 60+ export territories.
