As a leading China 10KV 630mA fuse manufacturer, we understand that the reliability of a medium-voltage electrical network often hinges on the most minute components. A 630mA (0.63A) rating at 10KV is a specialized specification typically reserved for the protection of potential transformers (PTs) and high-precision instrumentation circuits. These miniature fuse links are designed to isolate faults in voltage measurement systems without interrupting the main power flow, preventing costly damage to substation monitoring equipment.
Currently, the global industrial landscape is shifting toward more decentralized and intelligent power distribution. In Europe and North America, there is a surging demand for DIN standard and IEC-compliant fuses that can integrate with modern switchgear. In developing regions such as Southeast Asia and Africa, the focus remains on robust, weather-resistant protection for rural electrification projects. The 10KV 630mA fuse remains a staple in these markets due to its critical role in safeguarding the sensors that allow for remote grid management.
Ensuring Authority and Reliability through Rigorous Standards
Originating as "Yueqing Shuguang Fuse Factory" in 1992, we have over 30 years of specialized experience in power technology R&D. We integrate design, production, and testing under one roof.
Our company's quality assurance system is ISO9001:2000 certified. We strictly adhere to ANSIC37, DIN43625, BS2692, IEC60282, and VDE0636 standards.
All products have passed tests at the Electric Power Research Institute, National High-voltage Electrical Apparatus Quality Supervision, and Xi'an Research Institute.
The industry is currently witnessing several transformative trends. Firstly, there is a move toward environmentally friendly materials. Our production of high-voltage insulators and fuses now utilizes advanced polymers and lead-free alloys. Secondly, the miniaturization of components is a major demand from global procurement agencies. A 10KV 630mA fuse must be compact enough to fit into modern, space-saving ring main units (RMUs) while maintaining a high breaking capacity.
Modern buyers from the Middle East and Europe are no longer just looking for "cheap" parts. They require traceability and verified data sheets. Our "Shu Rong" brand products are favored because we provide comprehensive testing reports for every batch, satisfying the rigorous technical conditions required by international utility companies.
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 built a reputation for excellence. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
Our commitment to "Development by science and technology, and survival by quality" has allowed us to maintain a top-tier position in the industry. We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses, zinc oxide arresters, drop-out fuses, and insulators.
Based in Yueqing, we have direct access to the world's most efficient electrical component supply chain, ensuring fast lead times even for large wholesale orders.
As a factory, we can produce customized 10KV 630mA fuses to match specific dimensions (like 8*150mm or 55*520mm) and unique time-current characteristics.
We provide high-power tested, IEC-compliant products at competitive factory-direct pricing, eliminating middleman markups for global distributors.
Our highest technical performance meets an exhaustive list of international standards. This ensures that when you source from us, you are receiving a product that is globally compatible:
The "Shu Rong" brand is utilized by various provincial power companies across China and is a top-ranked seller for international export. We serve sectors ranging from urban grid substations to heavy industrial manufacturing plants.
