What size thermal cutoff is used in a Melitta MEK 17W

What size thermal cutoff is used in a Melitta MEK 17W

I have a Melitta Kettle, Model MEK 17W, the thermal cutoff is open. The numbers on the cutoff are warn off. I am looking for the temperature rating for this device so I can replace it. I am guessing the voltage will be around 250 @ 10 amps, not sure how high in temperature I should go. Anyone have any ideas.
