Question about relating thermal fuse ratings - Electronic Circuits Projects Diagrams Free

If I have a thermal fuse, rated for say, 10A at 100C. Would there be another fuse rated for less current but higher temperature that would open at the same point the 10A/100C fuse does? If so, what's the relationship between the two?

No relationship, the temperature is where it blows at, and the current is the maximum current it can pass.

Does this apply to thermal switches as well? Can I use fuses with different current ratings provided the temperature rating is the same?

Yes, as long as the current rating is higher than required.

Awesome. Thank you very much for the help!

If the current flowing causes a significant temperature rise it will cause it to blow at a lower ambient temperature which is normally a good thing.
