Abstract

A method is intended to make it possible to drive a PTC electrical load element with a switching unit with the highest possible operational reliability. For this purpose, the electric current is switched off if a predetermined current threshold value is exceeded, the magnitude of the current threshold value being determined from the operating parameters of the load element.
