額定動作溫度

（TF）

在僅通以不超過10mA的探測電流的條件下測得的使熱熔斷體導電狀態改變的溫度，熱熔斷體必須在上述溫度0/-10℃范圍內動作。

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

產品放置油槽內并通以不超過10mA電流值 ，然后以0.5K/min 至1K/min 的速度穩定升溫 ，熱熔斷體實際動作溫度值。

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）

熱熔斷體在規定的條件下通過額定電流且保溫168小時，其導電狀態不發生改變的最高溫度值或按IEC60691標準測試值。

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）

由制造廠規定的溫度，在此溫度下熱熔斷體導電狀態已改變，但其機械性能和電氣性能在規定的時間內不致減弱。

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.
