Established in 1992 in Yueqing, Zhejiang—the electrical capital of China—Wenzhou Shuguang Fuse Co., Ltd. has evolved from a local factory into a powerhouse in electrical safety technology. Integrating R&D, production, and global sales, we specialize in high-voltage current-limiting fuses and comprehensive power protection solutions.
Our commitment to excellence is backed by certifications including ISO9001:2000 and full compliance with international standards such as IEC, ANSI, DIN, and BS. We don't just supply fuses; we provide critical infrastructure security for power systems worldwide.
The transition toward renewable energy and the rapid adoption of Electric Vehicles (EVs) have fundamentally altered the landscape of power electronics. "CustomEvFuses" are no longer just passive components; they are vital safety barriers in high-energy density battery systems and charging infrastructure.
China's position as the world's leading manufacturer of electrical fuses is driven by the country's unparalleled industrial ecosystem. Wenzhou, specifically, hosts a supply chain synergy that allows for: (1) Rapid Prototyping: Turning bespoke requirements into physical samples within weeks. (2) Cost Efficiency: Achieving economies of scale that reduce unit costs without compromising on raw material quality (e.g., high-purity silver elements and ceramic bodies). (3) Rigorous Testing: Facilities like our own, equipped with high-power testing capabilities, ensure every batch meets global safety codes.
Our products are tested at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center. We strictly adhere to GB, IEC 60282, and DIN 43625 standards. Our quality assurance system ensures that whether you are sourcing for an industrial substation or a high-capacity EV charging station, the reliability remains industry-leading.
Yes. As experts in custom power electronics, we offer tailored design services to match your specific current and voltage requirements, ensuring perfect protection for your battery management systems (BMS).
We utilize advanced testing equipment and adhere to ISO9001 standards. Every product batch undergoes rigorous testing for thermal stability, breaking capacity, and electrical performance before leaving our factory.
Depending on the customization level, our integrated production line allows us to maintain efficient production cycles, often outperforming market averages for industrial fuse manufacturing.
