首先第一个问题，热熔体（温度保险丝）是不是非自复位热断路器？

非自复位热断路器的定义是：

' Y4 i' I5 m5 E6 p; j- x比较可知，thermal link只是一种特殊的thermal cut-out（只动作一次且需替换）， thermal link也符合non-self-resetting thermal cut-out的定义。再形象点，如果把thermal cut-out比作马，thermal link 属于母马而且还是白马的话，non-self-resetting thermal cut-out就是白马（包括公白马和母白马）。- q& u0 ~: \, @1 a K7 s' t& ?8 }

第二个问题，热熔体（温度保险丝）是否要去加入7.12.6警告语？" b* f1 z' T4 w- v9 T& D
回答是不需要，因为它不是通过断电来重置的（热熔体需替换来重置）。
