    Abstract: In order to ensure that the current path is interrupted along the entire length of fusible cut-out elements (4a,4b) in a reliable manner, said elements are provided with burn-up bodies that are arranged at a distance on a strip (5) that is made from an electroconductive material in capsules (8), whereby said bodies are connected by means of a continuous igniter wire (9) and ignition of one burn-up body triggers ignition of the rest. The burn-up bodies can be placed in a recess in the central support body, over which the strip (5) runs. Said burn-up bodies contain an explosive material with an ignition temperature of 245 DEG C. During burn-up, the explosive material gives off 480 J/g of energy, whereby a temperature of approximately 2,000 DEG C is reached and conversion into quenching gas, essentially nitrogen, occurs.

    Abstract: The invention relates to an apparatus for limiting an electrical current by using a PTC resistor being monitored by a monitor circuit. According to the invention, the monitor circuit issues a signal only after detecting the status of the PTC resistor for a defined time period after a PTC resistance change.

    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.

    Abstract: The invention is concerned with a binary voltage indicator for use with high- or medium voltage equipment. The indicator comprises a photoactive layer (5) which changes its reflectivity or emissivity when subjected to an electric field and which is applied directly onto the surface of a conductor. The photoactive layer is based on materials as used for low-voltage displays, such as electrophoretic films.
