ABSTRACT A self-limiting electrical heating device with an electrical resistance material the resistivity of which is changed by more than a power of 10 within a predetermined, narrow temperature interval and which is arranged between electrical conductors connectible to a voltage source, the conductors and the resis- tance material being enclosed in an electrically insulating cover, is described. The electrical resistance material (2) comprises 1) an electrically relatively non-conducting crystalline, mono- meric substance which melts within or near the predetermined, narrow temperature interval and which constitutes the outer phase, 2) particles of one or more electrically conducting material(s), distributed in the non-conducting material, 3) one or more non- conducting powdered or fibrous fillers, which are insoluble in the non-conducting material and which have a considerably higher melting point than this material, similarly distributed in the non-conducting material, whereby the weight ratio between com- ponents 1) and 3) is from 10:90 to 90:10.
