protective device 这在IEC60335-1中是有定义的.
device, the operation of which prevents a hazardous situation under abnormal operation
conditions
protective electronic circuit 也有定义
electronic circuit that prevents a hazardous situation under abnormal operating conditions
components in protective electronic circuits应当是保护电路中的一个部件(元件)
单独的热保护器属于protective device

谢谢你的回复
我有个新的理解 主要热保护的元件(预防危险的产生)就是Protective devices 其他的起到的作用就是功能性的 需要做24.1.4的测试 这样就比较好区分

很好的问题,易产生歧义.
问题本身好理解.
恐怕有些不好理解的是:"Protective devices shall not operate and sealing compound shall not flow out. However, components in protective electronic circuits are allowed to operate provided they are tested
for the number of cycles of operation specified in 24.1.4. "的后一句.
