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:( r3 H4 k% C0 r( p; A' M: Z! E( s

thermal cut-out that requires a manual operation for resetting, or replacement of a part, in order to restore the current

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)。

4 k1 h2 [2 X; e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)。
