Step 15: Thermal fuses

Picture of Thermal fuses
Sometimes, you can find an thermal fuse(s) in a microwave - often found near the magnetron. They are used to break the circuit from the mains if the magnetron overheats...

 I have two questions regarding thermal fuses:
At what temperature do they cut power?
And can they be reset after they trip?
I have acquired two from an old microwave and would like to put them to use.
if they have a number on them, try googling it to find a datasheet
 Thank you, but I have solved the problem. There were no datasheets, but I happened across another microwave, and it included a schematic. It had the same thermal fuses, and the schematic told me the trip temperatures. Thanks for the tip, though!
