產(chǎn)品簡介:
SET合金型溫度保險絲是一次性不可復位的熔斷裝置,廣泛應用于電器設備的過溫保護。溫度保險絲由具有低熔點的易熔合金
和助熔斷劑構成,封裝在塑料或陶瓷的外殼內。在正常工作情況下,易熔合金與兩根引腳保持連接。當溫度保險絲感受到異常發(fā)
熱并達到預定的熔點溫度時,易熔合金熔化,并在助熔斷劑的作用力下快速徹底斷開電路。有瓷管型和方殼型兩種外形供選擇,
額定電流1A~200A,動作溫度76℃~221℃,安規(guī)認證包括UL,cUL,VDE,TUV,PSE,KTL,CCC和環(huán)保RoHS、REACH認
證。

術語解釋:
● 熱熔斷體也稱為熱斷路器或溫度保險絲,在本文中這些不同名詞都代表同樣的產(chǎn)品,為一次性動作而不可復位的裝置。
Thermal-link: also known as thermal cutoff or thermal fuse, all are the same in this context, function one only, non-resettable.
● 額定動作溫度 Rated Function temperature (Tf ):

The temperature of the Thermal-link which causes it to change its state of conductivity with a detection current up to 10mA
as the only load.
允許偏差 Tolerance: +0℃, -10℃ UL,VDE,IEC標準 Standard
允許偏差 Tolerance: ±7℃ (僅限PSE標準)only PSE
實測熔斷溫度 Fuse temperature (Fuse-temp):
置于油池中,通10mA以下的負載電流,每分鐘升溫0.5℃~1℃,測斷開溫度。

The current used to classify a Thermal-link, which is the Maximum current that thermal cutoffs allow to carry and are able to
cutoff the circuit in safety.
● 額定電壓 Rated voltage (Ur):
溫度保險絲分類用,允許用于電路并安全斷開的最高電壓。
The voltage used to classify a Thermal-link, which is the Maximum voltage that is allowed to apply to the circuit in which the
thermal cutoff is used.
