Abstract
A protection circuit includes an interruption device formed to interrupt a current path between a protection circuit input and a protection circuit output upon exceeding a predetermined temperature at a temperature measurement location, and a control device formed to generate a control signal depending on a current in the current path, wherein the protection circuit is formed to increase the temperature at the temperature measurement location or decrease the predetermined temperature, when the control signal indicates that the current in the current path is higher than a threshold value current.
