Abstract

A PTC heating module for heating a fluid may include at least one first electrically conductive contact electrode and at least one second electrically conductive contact electrode arranged spaced apart from each other, at least one insulator layer attached to the at least one first contact electrode and the at least one second contact electrode, and at least one PTC thermistor element having a thickness. The at least one PTC thermistor element may have a first main surface and a second main surface disposed opposite each other relative to the thickness. The at least one first contact electrode may be in contact with a contact area of the first main surface and the at least one second contact electrode may be in contact with a contact area of the second main surface. At least one of a clearance distance and a creepage distance may be greater than the thickness.
