What is the meaning of "rated operating temperature" in temperature fuse?

Question: What is the meaning of "rated operating temperature" in the temperature fuse?
 
Answer: The rated operating temperature refers to the temperature at which the thermal fuse changes its conductive state when only the detected current of not more than 10mA is used as the load. This temperature tolerance is within the range of +0 and -10℃.
 
English: the temperature which a thermal cutoff changes its state of conductivity to open a circuit with detection current of 10ma or less as it loads. the temperature tolerance is+0, -10℃.
