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？! \- D# v1 k( ~% a ?6 H3 y
回答：: }2 d, U' c1 E! a) L/ E
非自复位热断路器的定义是：
+ p# n- l9 N4 {/ E" E4 R( ^7 p3.7.5 non-self-resetting thermal cut-out
' m, o9 a7 e* _; w. n: tthermal cut-out that requires a manual operation for resetting, or replacement of a part, in order to restore the current& _. h& H1 j \' {) `2 R8 }+ V
- {# I! [" m5 e+ G6 t6 M& U3 y* j热熔体（温度保险丝）的定义是：+ o7 U4 P: h/ @( S9 {" U
3.7.7 thermal link r; o% {/ u) P( u
thermal cut-out which operates only once and requires partial or complete replacement
$ a& C1 _& @6 O' b( z, C9 B0 f5 i; @2 z) o$ U- G# W. B
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）。
