Thermal fuses parameters term

Thermal fuses have rated current and voltage,Fusing temperature (Tf),Use temperature (Th),  Maximum temperature (Tm),Customers must be used under specified parameters.Otherwise the product can not be used normally

Rated operating temperature (Tf):
Thermal fuses according to the standard method of testing,Changing the temperature of the conductive state.According to IEC6091-based safety standards,Thermal fuse action must be within the rated operating temperature range of + 0 / -10 ℃.(Japan Electrical Supplies Management Act provides a tolerance range of ± 7 ℃ within the action).


The actual operating temperature:
The thermal fuse is heated in the silicone oil tank at a rate of 0.5-1 ° C per minute,Detection current less than 10mA conditions, the measured fusing temperature.It is the actual operating temperature of the thermal fuse.


Maintain temperature (Th):

When the thermal fuse passes the rated current,Can hold for 168 hours without changing the maximum temperature of its conductive state.


Extreme temperature (Tm):
    
Thermal fuse can withstand 10 minutes,And never re-connected to the phenomenon, the maximum temperature.


Rated current (Ir):

The maximum current that the thermal fuse can carry.

Rated voltage (Ur):

Thermal fuse maximum operating voltage.
