Each of our circuit breakers is meticulously equipped with high-quality, pure spring operating mechanisms. This ensures a straightforward and efficient structure that stands the test of time. These mechanisms simplify the construction, offering unparalleled reliability and seamless operation. The mechanical endurance of our circuit breaker's operating mechanism is engineered to exceed an impressive 10,000 cycles. This robust endurance capacity demonstrates the superior quality and durability of our product. The mechanism can endure over 10,000 operations, making it remarkably easy and convenient for maintenance. It adheres to the highest standards for being oil-free and air-free, employing a self-energy arc-extinguishingprinciple that significantly minimizes the operational power required by the mechanism, thereby enhancing the overall operational reliability of the entire product.
Our flanges incorporate a sophisticated dual-seal design. The outer seal ring is crafted to be water-proof, while the inner seal ring ensures gas tightness. This dual-seal strategy substantially reduces any potential leakage, rendering the product exceptionally suited for outdoor applications.
