Our cutting-edge circuit breakers are innovatively designed with pure spring operating mechanisms, ensuring an elegantly simple structure. This design facilitates outstanding reliability, setting the standard for dependable performance. The mechanical endurance of our advanced operating mechanism exceeds an impressive 10,000 cycles, testifying to its durability and robustness, ensuring seamless functionality over time, while remaining highly convenient for maintenance. The design upholds stringent requirements for being oil-free and air-free, incorporating a self-energy arc-extinguishing principle. This principle effectivelyreduces the operational power needs of the mechanism, thereby enhancing the operational reliability and longevity of the product. This ensures exceptional performance in all conditions.
The flangesystem features a dual-seal structural design with an outer waterproof seal ring complemented by an inner gas-proof seal ring. This dual protection significantly minimizes leakage, making the product exceptionally suited for outdoor operations, even under challenging conditions.
