The so-called "fuse mechanism" is a clause set from the trading rules to prevent sharp fluctuations in stock prices, mainly to prevent irrational sharp falls, maintain the stability of the securities market, and protect the interests of small and medium investors.

The mechanism of "circuit breaker" originated from new york Stock Exchange. For investors, it is particularly important to note that the "fuse mechanism" clause has the characteristics of not intervening in the rising market, but only intervening in the irrational plunge. Therefore, it is a historic breakthrough to introduce the "fuse mechanism" clause into the trading rules of China stock market. This indicates that the construction and supervision of the securities market have substantially turned to the track of "protecting the interests of investors".
