TF (Rated Functioning Temperature)
The temperature of the thermal cutoff which causes it to change its state of conductivity with a detecion current up to 10 mA as the only load. Under the UL/IEC standards the tolerance is +0℃, -10℃.
 
TH (Holding Temperature)
The maximum temperature of the thermal cutoff at which it will not change its state of conductivity for 168 hours while conducting its rated voltage. It is called Th for short by UL and called Tc by IEC/VDE.
 
TM (Maximum Temperature Limit)
 
The temperature of the thermal cutoff, up to which the mechanical and electrical properties of the thermal cutoff, having changed its state of conductivity, will not be impaired for 10 minutes.
 
 
Operating principle of RYD thermal fuse

RYD thermal fuse is made up of star contact,spring and thermal pellet
In the picture, we can see that current is started from the left down-lead on the right.When the external temperature reaches operating temperature,the thermal pellet would be melted,which would cause the spring loose,and then separate the connection between star contact and the left down-lead. Thus, the current would be totally cut.
 
Trait
The products have the ability to cut circuit immediately for high current,with non-resettable. The thermal fuse has low internal resistance itself,small size that easy to install. The products are sensitive to external temperature and the operating temperature has high accuracy and stability.

Performance Characteristics
1 No load operating temperature test(TF):
Fuse placed in the 0-300 degree temperature test box(oil temperature testing), Then warming to rated operating temp of sample in the speed of 0.5k/min to 1k/min the test result should within +0/-10C of rated TF.
2 No load Holding temperature test(TH):
Fuse placed in the test box, applide current/ voltage does not exceed the amount of Set range, the Testing TH temperature does not exceed the scope of Th temperature of the test in 7days.
3 Contact resistance:
A measurement of contact resistance betwween E and the case should be no more than 5mohm.
4 Electrical strength:
Between lead and metal casing is conductive, so do not do this test.
5 Wet test:
Standard experimental conditions
For TF<=100C thermal fuse
Environmental Temp:40+/-3C
Humidity:RH90/95%
For TF>100C thermal fuse
Humidity:RH90/95%
