Under normal circumstances, the price of DC small circuit breakers will be relatively high. This is mainly due to the DC circuit breaker in the working mode, working principle, physical structure and other aspects of the AC circuit breaker has a large difference, resulting in its high production cost. In addition, the DC circuit breaker is also special in the application scenario, and needs to meet some special technical requirements, which will also increase its price.

The AC circuit breaker has a wide range of applications and relatively low production costs, so the price is usually relatively close to the people.

However, the price is not static, it will be affected by market supply and demand, product quality, brand influence and other factors. Therefore, the specific price difference also needs to be judged according to the market situation.

In the selection of circuit breakers, in addition to considering the price factor, should also be based on the actual application scenario, circuit type, protection level, rated current and other requirements to select the appropriate circuit breaker to ensure the safe and stable operation of the circuit. At the same time, you can also compare different brands and models of products when buying, and choose cost-effective circuit breakers.
