Abstract (en)

[origin: EP0923086A1] The critical temperature (Tc) is below the switching temperature. Device for protecting a current consumer from overload has a resistor, between 2 contact terminals, the electrical resistance of which increases suddenly when a certain switching temperature is reached. This consists of a polymer matrix, a first filler powder of conductive material and a second filler powder containing phase transition material(s) undergoing a phase transition at a critical temperature (Tc) at which transition heat is taken up.
