术语解释EXPLANATION OF TERMS 

*Tf 额定动作温度 Rated functioning temperature 

热熔断体在规定的条件下其导电状态发生改变的温度值。按照IEC60691标准测试，其动作温度为Tf + 0℃。

This rating is measure according to IEC60691 Standards and states that the
Thermal-links will operate within Tf + 0℃ of the Rated Functioning Temperature .

*实测动作温度 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 的速率稳定升温，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 to 1K/min and detective current 10mA or less.

*Th – 保持温度 Holding temperature 

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-links will not cause a change in state of conductivity to open circuit while conducting rated current for 168 hours or according to IEC60691.

*Tm – 最高极限温度 Maximum temperature limit

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