The global demand for Motor Fuses and high-voltage circuit protection is surging as industrial automation accelerates. In the current commercial landscape, fuses are no longer simple safety components; they are critical "intelligent" guardians of multi-million dollar machinery. Globally, the shift toward renewable energy integration and the modernization of aging power grids have driven the market to seek more reliable, high-breaking-capacity solutions.
Technological trends are leaning towards miniaturization and environmental sustainability. Modern OEM motor fuse manufacturers are focusing on DIN-standard current-limiting fuses that offer lower power loss and higher thermal stability. With the rise of the Electric Vehicle (EV) industry, high-voltage DC fuses have become a cornerstone of technological development, requiring factories to innovate beyond traditional AC protection.
Procurement teams in Europe, the Middle East, and Southeast Asia are increasingly looking for "One-Stop" OEM partners in China. The demand focuses on high compliance with IEC60282 and VDE0636 standards, competitive lead times, and the ability to customize fuse links for unique industrial environments like offshore wind farms or high-altitude power stations.
Located in Yueqing, Zhejiang Province—the electrical capital of China—Wenzhou Shuguang Fuse Co., Ltd. is a power technology enterprise integrating research, development, production, sales, and service.
The predecessor of our company was the "Yueqing Shuguang Fuse Factory" established in 1992. With over three decades of experience, we have evolved from a local manufacturer into a globally recognized supplier of high-voltage current-limiting fuses and power capacitor protection systems.
Contact Our Engineering TeamWe are designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels. Our product portfolio includes:
Our company's quality assurance system is complete, having passed ISO9001:2000 quality system certification. All performance indicators are tested and qualified by:
Being based in Yueqing allows us access to a world-class electrical supply chain, reducing raw material costs and production lead times.
We invest heavily in process flow optimization. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance.
New products can be customized and produced at any time according to user needs, including specific voltage ratings and physical dimensions.
Our products are exported to Southeast Asia, the Middle East, Africa, and Europe, establishing a high reputation among global utility providers.
Our "Shu Rong" brand products are designed for diverse and demanding electrical environments.
Protecting provincial power companies and distribution networks with high-voltage expulsion fuse links.
Safe operation of high-power motors in factories via current-limiting HRC fuses.
Protecting oil-immersed transformers and solar power collection systems.
In recent years, our company has developed rapidly, and its economic and social benefits have improved significantly. We continue to deepen and improve the quality management system. While vigorously developing new products, we have always attached importance to the process flow.
The highest technical performance of our fuses meets ANSIC37.42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, and many more. This ensures that every motor fuse leaving our factory is capable of handling extreme electrical faults without compromising safety.
"The company adheres to the principle of 'Development by science and technology, and survival by quality'. We sincerely welcome customers from home and abroad to discuss cooperation."
The products of Wenzhou Shuguang Fuse Co., Ltd. are exported to various provincial power companies in China, forming a complete sales network across the country. Beyond our borders, our China OEM Motor Fuse products have gained massive traction in Southeast Asia, the Middle East, Africa, and Europe.
