a股取消了熔断机制，不过还有a股熔断的相关规则，并且交易所可以根据市场行情实时暂停股票交易。a股熔断条款设置了5%和7%两个阈值，当指数下跌5%时，交易所暂停交易15分钟，当指数下跌7%时，交易所暂停交易至收市，不过近几年一直都未实际实施这个规则。

需要注意的是新股上市交易没有涨跌幅限制（沪深两市上市首日没有涨跌幅限制，创业板和科创板上市前5个交易日没有涨跌幅限制），但设有临时停牌机制，临时停牌就是熔断机制，沪市新股上市首日涨跌幅为44%，当沪市新股上市首日涨跌幅达到规定的限制，停牌30分钟。

深市新股上市首日盘中涨幅与开盘涨幅之差首次达到10%时，交易所对其实施临时停牌30分钟，创业板和科创板新股上市盘中涨幅与开盘涨幅之差首次达到30%，停牌10分钟，复牌后涨跌到60%的，再停10分钟，不过停牌的时间不管多长，都要在14:57复牌。
