保護性器件 Protective device 和 Components in the protective electronic circuits 的區別?
熱保護器屬于那種?
對En60335-1 11.8節的理解

protective device 這在IEC60335-1中是有定義的.
device, the operation of which prevents a hazardous situation under abnormal operation
conditions
protective electronic circuit 也有定義
electronic circuit that prevents a hazardous situation under abnormal operating conditions
components in protective electronic circuits應當是保護電路中的一個部件(元件)
單獨的熱保護器屬于protective device

謝謝你的回復
我有個新的理解 主要熱保護的元件(預防危險的產生)就是Protective devices 其他的起到的作用就是功能性的 需要做24.1.4的測試 這樣就比較好區分

很好的問題,易產生歧義.
問題本身好理解.
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.
