Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the Electrical Capital of China. Over the past three decades, we have evolved into a premier power technology enterprise that seamlessly integrates advanced research, development, precision production, and global sales service.
Our journey has been defined by a commitment to the principle: "Development by science and technology, and survival by quality." We specialize in high-performance circuit protection, catering to the evolving needs of modern electrical grids and industrial infrastructures worldwide.
In the modern industrial era, NH (Niederspannungs-Hochleistungs) fuses are critical. The demand for HRC (High Rupturing Capacity) fuses is surging due to the increasing complexity of industrial automation and the need to protect sensitive electronics from massive short-circuit currents.
Global trends toward decarbonization have made NH fuses indispensable in Solar PV systems and Wind Power grids. As a leading China factory, we specialize in fuses designed to handle the unique DC and AC load profiles of green energy installations.
The rise of EV charging infrastructure across Europe and Southeast Asia requires robust, localized protection. Our ChinaFuseNh products provide the reliability needed for high-frequency switching and rapid circuit interruption in urban power hubs.
