Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China." As a premier power technology enterprise, we integrate research, development, production, and high-tier service. Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory," and for over three decades, we have remained at the forefront of circuit protection innovation.
We are designated by the Ministry of Electric Power Industry to manufacture high-voltage fuses, motor-rated current-limiting fuses, and specialized protection for power capacitors and transformers.
The global industrial landscape is undergoing a massive shift toward automation and high-efficiency motor systems. High-Quality Motor Rated Fuses are no longer simple safety components; they are critical assets in protecting multi-million dollar investments in mining, oil and gas, and heavy manufacturing.
The transition to Industry 4.0 requires fuses that can handle higher breaking capacities and offer precise coordination with modern vacuum contactors. Our Motor Rated Fuses are engineered for these exact parameters.
With global power grids moving toward higher transmission voltages, the demand for reliable 12kV, 24kV, and 36kV current-limiting fuses has surged. We meet this demand with rigorous IEC testing protocols.
Renewable energy sectors, including wind and solar farms, utilize large motors for positioning and cooling. Our fuses provide the robust protection required in these harsh, remote environments.
Modern procurement now prioritizes components that integrate with digital monitoring. Our R&D focuses on thermal stability and long-term reliability for smart grid infrastructure.
Our commitment to excellence is backed by certifications from the highest authorities in power technology. Every Motor Rated Fuse produced in our Yueqing factory undergoes stringent testing at the High-power Test Station of the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
We strictly adhere to international standards including IEC 60644 (Specification for high-voltage fuse-links for motor circuit applications), IEC 60282-1, DIN 43625, and ANSI C37.42. This ensures that our global partners receive products that are fully interchangeable and compliant with local grid requirements.

Procurement officers from Europe, the Middle East, and Southeast Asia look for a balance of cost-efficiency and technical reliability. As a leading China factory, we provide localized solutions for diverse environments.
Used in medium-voltage motor starters across steel mills and chemical plants where high inrush currents are standard. Our fuses handle repetitive starting stresses without fatigue.
Specialized high-voltage HRC fuses designed for oil-immersed transformer backup protection, ensuring safe operation in energy-dense environments.
Critical protection for water pumping stations, railway power systems, and metropolitan HVAC chillers that require 24/7 uptime.
With 30 years of manufacturing history, our "Shu Rong" brand is a symbol of trust. We have witnessed the evolution of fuse technology from 1992 to today.
Located in the electrical cluster of Yueqing, we have access to the world's most efficient supply chain for copper, ceramics, and silver components.
Unlike standard trading companies, we are a direct factory. We can customize fuse characteristics (K-rated, T-rated, etc.) according to specific user needs.
In recent years, our economic and social benefits have improved significantly. We continue to deepen and improve our quality management system. While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. All performance indicators are in line with the corresponding technical conditions, and new products can be customized and produced at any time according to user needs.
Our 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 and work together for the prosperity and development of the electric power industry. With a complete sales network throughout China and successful exports to Southeast Asia, the Middle East, Africa, and Europe, our domestic product sales consistently rank among the top in the industry.
Whether you require standard 100A NH00 fuses or complex 55*520mm high-voltage current-limiting fuses, Wenzhou Shuguang Fuse Co., Ltd. is your reliable partner for high-quality motor rated fuses. We don't just sell products; we provide peace of mind for your power infrastructure.
