The successful adoption of the self-blast arc-extinguishing principle has endowed the circuit breaker with outstanding advantages, including strong breaking capability, short arcing time, and extended electrical lifespan.
The circuit breaker adopts a self-blast arc-extinguishing chamber based on a new arc-extinguishing principle, featuring a hybrid structure combining self-blast thermal expansion and an auxiliary puffer mechanism. This design fully utilizes the energy of the arc itself, enhancing arc-extinguishing capability and significantly reducing the operational power requirements of the mechanism. Compared to conventional puffer-type arc-extinguishing chambers, it offers stronger breaking performance, shorter arcing time, and a full breaking time of just 3 cycles. It also boasts extended electrical lifespan, with a full-capacity breaking ability of up to 22 times.
The structure is simple yet highly reliable. The self-blast arc-extinguishing principle ensures dependable breaking performance for rated short-circuit currents as well as any fault currents, providing ample arcing time margin. Inheriting the structural features of puffer-type circuit breakers, it minimizes the number of components in the arc-extinguishing chamber, enhancing the electrical reliability of the product.
