这个主要是指在非正常动作的, 又可以分为自复位(self-resetting 和和非自复位的(non-self-resetting).

所以6楼中第一章图片是用在冰箱中的温控器,一般情况下是对的
* f) p7 f# [* t; q6 c! [: V+ T4 P但是第三张图片绝对不能说是thermal cutout. 也许用在A产品中是thermal cutout但是用在B产品中就是thermostat了. 举个例子,sandwich maker(三明治炉)中很多温控器都是这个样子的. h& u, E4 r9 A8 d8 l

另外, 2楼的解释也有问题,前看下面的条款$ V6 a6 ?) F j- Z( R
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not3 N! f: K* B2 s% L

60335-1 的A2已经修改了,所以thermal link 不一定要有证书的./ U$ y8 L" v& B8 M3 L
