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？. N* C' l6 t/ `. r7 K* B
回答：5 o& M0 p9 E' N+ N
非自复位热断路器的定义是：" h% t2 S8 S$ F8 ]3 i) ]
3.7.5 non-self-resetting thermal cut-out0 z. W& F; a9 a# B
thermal cut-out that requires a manual operation for resetting, or replacement of a part, in order to restore the current

热熔体（温度保险丝）的定义是：

& L0 V) A+ D' \! }thermal cut-out which operates only once and requires partial or complete replacement1 o, `: U1 N# W' R1 p
7 @" g0 d# b' e- _1 B, l$ ^: 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）。8 ^7 `- T' S& b
