Electrical Protection Circuit Breakers Manufacturers, Medium and Low Voltage Circuit Breakers Factory in China.
01
Our in-house factory handles core processes—metal machining, injection molding, coil winding, contact component preparation, and final assembly—without outsourcing key parts, ensuring greater stability and delivery control. Our flexible production lines enable rapid switching across specifications to meet OEM/ODM customization needs.
02
The testing center simulates real-world conditions including temperature extremes, load surges, breaking capacity, electrical endurance, dielectric strength, and IP ratings. This transforms theoretical parameters into validated engineering data, ensuring reliable performance in demanding scenarios like industrial cycling, humid environments, and grid fluctuations.
03
Through raw material batch management and full-processtraceability, every unit undergoes key component screening beforeassembly. Automated testing minimizes human error, ensuringconsistent breaker quality suitable for high-volume overseas applications.
Innovation & Customization
Our core engineering team has over a decade of deep industry expertise and is well-versed in
major circuit breaker systems, enabling rapid functional upgrades, performance matching,and structural optimization. We support multi-dimensional customization covering structure,appearance, electrical parameters, and modular functions, providing comprehensive
OEM/ODM solutions.
Engineering Excellence
We possess extensive experience in installation, commissioning, and grid connection, alongwith in-house capabilities for power distribution cabinet production and field application. Thisenables us to provide rapid, practical technical assessments and solutions for projects. For ouroverseas clients, we offer multi-language support, product selection guidance, certification
documentation, parameter adaptation, and transparent delivery tracking.
