In the complex landscape of medium and high-voltage electrical distribution, the 63.5*359mm High-Voltage HRC (High Rupture Capacity) Fuse stands as a critical benchmark for safety and reliability. As a leading China 63.5*359mm manufacturer, Wenzhou Shuguang Fuse Co., Ltd. specializes in the production of DIN-standard fuse-links that are essential for protecting transformers, switchgear, and motors from the catastrophic effects of overcurrent and short circuits.
Our 63.5*359mm series is engineered specifically to meet the stringent demands of 12kV, 24kV, and 36kV systems. With over three decades of manufacturing experience, we integrate advanced material science—utilizing high-purity silver elements and chemically treated quartz sand—to ensure precise arc quenching and current-limiting performance.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. As a power technology enterprise integrating research, development, production, sales, and service, we have been at the forefront of the industry for over 30 years.
The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992. From our humble beginnings, we have evolved into a sophisticated manufacturing hub. Our journey is defined by a relentless pursuit of quality, ensuring that every 63.5*359mm fuse-link that leaves our facility meets international safety standards.
