Our cutting-edge circuit breakers are meticulously engineered with pure spring operating mechanisms, ensuring a simple yet immensely reliable structure. This innovative design simplifies the overall structure, greatly enhancing reliability, as the mechanical endurance of the operating mechanism impressively surpasses 10,000 cycles. This means durability, ease of maintenance, and unparalleled efficiency, meeting the stringent oil-free and air-free requirements. By utilizing a self-energy arc-extinguishingprinciple, it remarkably reduces the operation power demand, thereby enhancing the product's operational reliability.
The flanges are ingeniously designed with a dual-seal structural design; the external seal ring provides water resistance while the internal seal ring ensures gas sealing. This design significantly curtails potential leakage, making it ideally suited for outdoor operations, even in challenging conditions.
