Precision-engineered surge protection and circuit breakers for high-voltage DC systems and smart industrial applications.
Zhejiang Shuorui Electric Co., Ltd. is located in Liushi, Wenzhou, Zhejiang, the electrical capital of China. It is the core area of the electrical industry and gathers many excellent electrical companies and rich industry resources. As a modern company integrating R&D, production and sales, Shuorui Electric is committed to providing customers with high-quality electrical products and solutions.
The company always adheres to the business philosophy of "the most cutting-edge technology, the best quality, the most sincere service, and the most favorable price", striving to maintain a leading position in the fierce market competition.
Shuorui Electric has continuously increased its investment in technology research and development, established a high-quality R&D team, focused on the development of new products and technological innovation. We ensure that every product, from miniature circuit breakers (MCB) to smart control boxes, is at the forefront of the industry.
Our focus includes smart remote control switches and photovoltaic DC distribution switches, catering to the rapid growth of the global renewable energy sector.
In the production process, Shuorui Electric strictly controls every link, from the purchase of parts to the delivery of the whole machine. We have established strict quality inspection standards and introduced advanced production equipment. Our goal is to satisfy every customer and reassure every user by meeting international standards consistently.
Every product is carefully designed, with a novel and beautiful appearance, in line with modern aesthetics and high functionality.
The global electrical market is undergoing a fundamental shift. As the world moves toward Industry 4.0 and renewable energy integration, the role of a Miniature Circuit Breaker (MCB) manufacturer has evolved from a simple hardware provider to a critical partner in system reliability and fire prevention.
Being based in Liushi, Wenzhou, gives us unparalleled access to a vertical supply chain. From raw copper sourcing to advanced silver-alloy contact point manufacturing, the cluster effect allows us to offer high-spec products like 1500VDC surge protectors at highly competitive wholesale rates. This efficiency is the cornerstone of China's manufacturing advantage.
We are no longer just making "breakers." Our current production lines integrate Internet of Things (IoT) capabilities. Our WiFi Intelligent Reclosing and Overvoltage protectors represent the future of electrical management, allowing facility managers to reset circuits remotely via smartphones, reducing downtime by up to 80%.
Our expertise is backed by years of field data. For global procurement teams, "Reliability" means more than just a certificate. It means documented performance in extreme environments—from the high UV exposure of desert photovoltaic farms to the humid conditions of tropical industrial zones.

Certified Quality
Pre-shipment Testing
Technical Support
Navigating international standards like IEC 60898-1 or EN 60947-2 is complex. As a veteran MCB manufacturer, Shuorui provides full compliance documentation for global markets. We support local distributors with:
Our 1000VDC and 1500VDC SPDs and breakers are specifically designed for the harsh DC environments of utility-scale solar arrays, preventing surge damage during lightning strikes.
Integrating WiFi-connected smart switches allows homeowners to monitor energy consumption and protect expensive electronics from overvoltage fluctuations in unstable grids.
Ensuring continuous uptime in factories with self-resetting undervoltage protectors, minimizing manual intervention and maximizing machine lifecycle.
A glimpse into our advanced production lines and the dedicated team behind Shuorui Electric.
We leverage the Liushi industrial cluster to integrate high-precision components with advanced arc-quenching technology. Our breakers undergo 100% triple-testing for thermal, magnetic, and dielectric strength before shipping.
Yes, we specialize in OEM/ODM services. We can customize trip curves (B, C, D) and voltage ratings for specific regional grids, including 110V systems for the Americas and 240V for the UK/Middle East.
DC circuits are more prone to sustained arcing. Our PV-specific MCBs and SPDs are built with specialized internal barriers and high-capacity copper contacts to safely extinguish DC arcs up to 1500V.
For standard models, we maintain a rolling stock. Custom OEM orders typically have a lead time of 15-25 days depending on the volume and certification requirements.
Looking to the future, Zhejiang Shuorui Electric Co., Ltd. will continue to increase investment in research and development. We expand product lines and give back to customers with higher standards and better services. We look forward to working hand in hand with more partners to create a better future together.
