Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global leader in power technology. Located in the "Electrical Capital of China"—Yueqing, Zhejiang—we specialize in the research, development, and high-volume production of advanced motor fuses and high-voltage protection devices.
As a designated manufacturer for the Ministry of Electric Power Industry, our company has built a legacy of trust and technical proficiency. We don't just manufacture fuses; we engineer safety for the world's most critical electrical infrastructures.
Designated by the Ministry of Electric Power Industry. Our "Shu Rong" brand is synonymous with high-performance high-voltage current-limiting fuses and transformer protection globally.
The role of high-quality motor fuses in the modern industrial landscape.
In the era of Industrial 4.0, the global demand for China High-Quality Motor Fuses has skyrocketed. As industries transition toward automation and smart manufacturing, the protection of electric motors—the heart of industrial operations—has become paramount. A single motor failure can lead to catastrophic downtime, costing enterprises millions in lost productivity.
Modern motor fuses are now being integrated with monitoring systems to provide real-time data on electrical stress and thermal health, aligning with the rise of smart grids across Europe and North America.
With the surge in wind and solar farms, high-voltage current-limiting fuses are critical for protecting power capacitors and transformers from transient overcurrents in volatile renewable circuits.
The Electric Vehicle (EV) revolution has created a need for specialized, compact EV fuses capable of handling high DC voltages while maintaining a small footprint within battery management systems.
Global enterprises demand compliance. We deliver certified excellence.
International procurement managers prioritize reliability and standard compliance above all else. At Wenzhou Shuguang Fuse, our products undergo rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our DIN43625 and VDE0636 compliant back-up fuse-links are essential for European industrial machinery, ensuring seamless integration into existing DIN-standard enclosures.
Fully compliant with IEC 60282-1, IEC 60644, and IEC 60470, our fuses meet the global benchmark for high-voltage current-limiting fuse performance and motor circuit protection.
Our highest technical performance meets ANSI C37.42 requirements, allowing us to serve the demanding North American utility and industrial markets.
Solving real-world electrical challenges across diverse industries.
In the Middle East and Southeast Asia, our oil-immersed transformer fuses are utilized to protect submersible pumps and refinery infrastructure. These fuses are engineered to withstand extreme thermal fluctuations and corrosive environments, ensuring continuous power for critical extraction operations.
In African and Australian mining sites, high-voltage motor fuses protect massive crushers and conveyor systems. Our "Shu Rong" brand fuses provide high breaking capacity, preventing damage from high-energy faults in isolated, off-grid power systems.
Across provincial power companies in China and municipal utilities in Europe, our drop-out fuses and zinc oxide arresters safeguard residential and industrial distribution transformers, reducing the risk of wide-scale blackouts during lightning strikes or grid surges.
As a leading China Motor Fuse Factory, we offer more than just products; we offer a partnership rooted in stability and innovation. Our competitive edge is built on three pillars:
