額定動(dòng)作溫度

（TF）

在僅通以不超過(guò)10mA的探測(cè)電流的條件下測(cè)得的使熱熔斷體導(dǎo)電狀態(tài)改變的溫度，熱熔斷體必須在上述溫度0/-10℃范圍內(nèi)動(dòng)作。

Temperature of the thetmal-link which causes it to change its state of conductivity with a detection current up to 

10mA as the only load. Thermal fuse must be fusing within the scope of +0/-10℃.

熔斷溫度

Fusing-off 

temperature

產(chǎn)品放置油槽內(nèi)并通以不超過(guò)10mA電流值 ，然后以0.5K/min 至1K/min 的速度穩(wěn)定升溫 ，熱熔斷體實(shí)際動(dòng)作溫度值。

The fusing-off temperature indicates value measured in the test oil bath and temperature be increased steadily 

with a rate of rise between 0.5K/min and detective current 10mA or less.

保持溫度

（Th）

熱熔斷體在規(guī)定的條件下通過(guò)額定電流且保溫168小時(shí)，其導(dǎo)電狀態(tài)不發(fā)生改變的最高溫度值或按IEC60691標(biāo)準(zhǔn)測(cè)試值。

The maximum temperature at which a thermal-link will not cause a change in state of conductivity to open circuit 

while conducting rated current for 168 hours or according to IEC60691.

最高極限溫度

（Tm）

由制造廠規(guī)定的溫度，在此溫度下熱熔斷體導(dǎo)電狀態(tài)已改變，但其機(jī)械性能和電氣性能在規(guī)定的時(shí)間內(nèi)不致減弱。

Temperature of the thermal-link stated by the manufacturer , Up to which the mechanical and electrical properties 

of the thermal-link , Having changed its state of conductivity , Will not be impaired for a given time.
