The circuit breakers are ingeniously designed with pure spring operating mechanisms, ensuring a streamlined and simplistic structure, which grants the system a simplified architecture, and a remarkably high level of reliability. The mechanical endurance for the operating mechanisms surpasses an impressive 10,000 operational cycles, demonstrating longevity and durability, ensuring the system is effortlessly maintainable, as it meets the stringent requirements for being oil-free and air-free. Utilizing the innovative self-energy arc-extinguishing principle,this product significantly reduces the operational power demands of the mechanism while enhancing the overall operational reliability of the product.
The flanges are crafted with a dual-seal structural design. The outer seal ring offers robust water-proofing, and the inner seal ring ensures a gas tight barrier. As a result, the potential for product leakage is greatly minimized, rendering it exceptionally suitable for outdoor operations.
