As the world pivots toward net-zero emissions, the demand for high-performance DC Circuit Breakers 1000V has reached an all-time high. From the vast solar farms in the Australian Outback to residential PV installations in Germany and EV charging networks in California, 1000V DC systems have become the industry standard for balancing efficiency and safety.
Technological shifts are moving away from traditional 600V systems toward 1000V and even 1500V architectures. This transition allows for longer string lengths in PV arrays, reducing the amount of wiring and the number of combiner boxes needed, which significantly lowers the Total Cost of Ownership (TCO) for large-scale utility projects.
Supporting renewable energy grids across 50+ countries with certified DC safety components.
Modern DC breakers are evolving into "Smart Breakers" capable of real-time current monitoring and remote tripping through IoT protocols.
Advanced magnetic quenching technology ensures that 1000V DC arcs are extinguished within milliseconds, preventing catastrophic fires.
Battery Energy Storage Systems (BESS) require bi-directional DC protection, a core focus of our R&D for 2024 and beyond.
Foshan SDEV Charger Co., Ltd. is a trusted manufacturer of protective components for photovoltaic systems across the globe. Our experience of working in the electrical industry for more than 30 years allows us to create solar DC components that comply with the latest DC standards. Through our focus on solar DC protection design, production, and marketing, we can bring brand-building PV protection solutions.
With the inheritance of 30+ years of experience in the research and production of DC protection products, we are continuously dedicated to the EV charging field. In recent years, SDEV has attentively invested resources in research on EV-related products, successively manufacturing other types of products, thus reaping wide market popularity across the world.

Operating as a China DC Circuit Breaker Factory, we control the entire lifecycle of our products—from raw material sourcing of high-grade copper and flame-retardant plastics to final assembly and testing. This ensures that even during global supply chain disruptions, we maintain a steady output for our international partners.
Our strategic location in Foshan allows us to leverage world-class logistics and manufacturing clusters. We pass these cost savings onto our clients, offering competitive wholesale pricing for high-quality 1000V DC components that meet or exceed European and American performance benchmarks.
Unlike traditional distributors, we are an OEM/ODM powerhouse. Our in-house engineering team can modify technical specifications—such as rated current (A), trip curves, or enclosure ratings (IP65/IP67)—to meet specific local electrical codes in your region.
Quality is the primary goal among each of our workshops since this leads to the best performance and safety for any Solar, Storage, and EV charging system. Our commitment to quality increased brand awareness for your company. To achieve our goal, our factory and products comply with UL, SAA, CB, CE, TUV, ISO, and RoHS standards.
Achieving our goals come from formulating new products based on the market demands through our in-house R&D team. Our efforts have led to our first UL508i listed patented DC switch within China and the DC-PV2 DC switch produced for the global market. With our cutting-edge PV protective products and EV chargers, we aim to create a long-term partnership with many renewables companies.
Our 1000V breakers protect massive PV arrays, ensuring that overcurrent events in one string don't compromise the entire field.
Compact designs like the DC Miniature Circuit Breaker are perfect for limited-space installations on factories and warehouses.
DC chargers require robust disconnects. Our 1000V components ensure safe operation during high-speed energy transfer.
When procurement managers and electrical engineers look for a DC Circuit Breaker 1000V Supplier, they aren't just buying hardware; they are investing in the long-term reliability of a multi-million dollar energy asset. A failure at 1000V isn't just a technical glitch—it's a significant fire hazard. This is why SDEV focuses heavily on Internal Resistance Reduction and Magnetic Blow-out technologies.
Global procurement needs are evolving. We see a significant rise in demand from Southeast Asia (Vietnam, Thailand) and Latin America (Brazil, Chile) where solar adoption is skyrocketing. These regions require products that can withstand high humidity and extreme UV exposure. Our IP65 and IP67-rated breaker boxes and disconnect switches are designed precisely for these harsh environments, featuring UV-resistant polymers and corrosion-resistant terminals.
As a leading Chinese factory, we also understand the importance of compliance. Whether you are installing a residential system in the UK requiring CE/UKCA or a commercial plant in the USA requiring UL listing, our products provide the necessary certifications to pass local inspections easily. Our mission is to simplify your supply chain while maximizing the safety and performance of every solar project you undertake.
