额定动作温度

（TF）

在仅通以不超过10mA的探测电流的条件下测得的使热熔断体导电状态改变的温度，热熔断体必须在上述温度0/-10℃范围内动作。

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℃.

熔断温度

Fusing-off 

temperature

产品放置油槽内并通以不超过10mA电流值 ，然后以0.5K/min 至1K/min 的速度稳定升温 ，热熔断体实际动作温度值。

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.

保持温度

（Th）

热熔断体在规定的条件下通过额定电流且保温168小时，其导电状态不发生改变的最高温度值或按IEC60691标准测试值。

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.

最高极限温度

（Tm）

由制造厂规定的温度，在此温度下热熔断体导电状态已改变，但其机械性能和电气性能在规定的时间内不致减弱。

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.
