Abstract: The resistor (1) has an electric resistor body (5) arranged between two contact terminals. The resistor body (5) is made of a connector material with a polymer matrix and an electrically conductive filler embedded in the matrix. The filer is in the form of a powder with particles whose average diameter is greater than 1 micron, preferably greater than 10 microns. The filler is a material which is harder and more resistant to oxidation than soot or silver. The resistor (1) is esp. used in a device for limiting and/or switching current. The resistor (1) is associated with a deforming arrangement (4) to elastically deform its resistor body (5). Upon a trigger signal (6) during operation of the device, the deforming arrangement (4) elastically changes the shape of the resistor body (5).

Abstract: The resistance has a pair of parallel terminal electrodes (1,2) in flat contact with a resistance body (3) which has a positive temperature coefficient characteristic. A varistor (40) lies in electrical contact with the resistance body which has 2 contact surfaces (50,51). The response point (60) of the resistance body is connected in parallel with the varistor through the surfaces. A number of series connected varistors (41,42,43,44) may contact respective meanders of a zigzag resistance body between the parallel terminal electrodes via respective contact surfaces (52,53).

Abstract: The invention relates to an electrical device with a PTC polymer element having a constriction. The constriction defines a web extending in a main current direction over a length longer than in the prior art, namely longer than 5 mm, preferably longer than 15 mm. Further, the aperture angle of the PTC polymer material at the ends of the web is larger than 100 DEG . A preferred choice of material is given, further. The invention achieves very high voltage-withstand capabilities.
