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？

8 `8 T9 U$ U. h* M( p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）。

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？. c$ t% ?- w: _
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）。3 k2 D7 p Y* W" L' Z3 ]4 {' H1 w. P
