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. |
