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-process traceability, every unit undergoes key component screening before assembly. Automated testing minimizes human error, ensuring consistent breaker quality suitable for high-volume overseas applications.
