I made a mistake in my previous message, my engine probe is indeed a KTY83 not a KTY84. I have 977Ohms to 21,7°c. It is written in the characteristics, the motor works normally between 70 and 120°c with peaks at 150°c. You can set the protection to 130°c but I use it at more than 250A continuously with a transmission ratio of 5 and a 230kg motorcycle + rider without it exceeding 70°c internally.
