To ensure every circuit breaker operates reliably under demanding conditions, we have established a comprehensive testing center equipped with key industry inspection devices, enabling full-process quality control from raw materials to finished products. The testing center is managed by an experienced team of engineers who strictly adhere to international and industry standards, covering performance, endurance, environmental, and structural testing. Each product undergoes multiple rounds of internal testing before delivery, ensuring consistency and reliability.

Engineers conduct multi-dimensional testing on circuit breakers, covering mechanical, electrical, thermal, environmental, and protection levels. These tests include temperature rise and overload, mechanical endurance, dielectric strength, short-circuit breaking capacity, high and low temperature cycling, flame retardancy, surge protection, and ingress protection (IP) ratings.
