Abstract: An electronic leakage current device a low-voltage power line, comprising: a moving contact and a fixed contact which can be mutually coupled/uncoupled; first sensor means for detecting a earth leakage current and for generating an electric signal which is indicative of the value of the earth leakage current; first electronic means which are electrically connected to the first sensor means in order to generate an electric tripping signal depending on the electric signal which is indicative of the value of the earth leakage current, said first electronic means generating the electric tripping signal after a preset minimum time interval; and actuation means, operatively connected to the moving contact, in order to perform, in response to the electric tripping signal: the separation of the moving contact from the fixed contact.

Abstract: An electronic earth leakage current device, comprising: a moving contact and a fixed contact which can be mutually coupled/uncoupled; and first sensor means for detecting an earth leakage current and for generating an electric signal which is indicative of the value of the earth leakage current; and first electronic means which are electrically connected to the first sensor means in order to generate, on the basis of the electric signal which is indicative of the value of the earth leakage current, an electric tripping signal; and actuation means, operatively connected to the moving contact, in order to perform, in response to an electric tripping signal, the separation of the moving contact from the fixed contact; Its particularity consists of the fact that it comprises: second sensor means for detecting one or more physical values which are indicative of the operating condition of the electronic device for protection against earth leakage current; and second electronic means, electrically connected t

Abstract: The power switch has a current flow path (7) with two supply terminals (1, 2) and a double breaking contact arrangement. The contact arrangement includes two series connected contact systems (10, 15), in which the current flow path extends in two sections guided parallel to one another. Said sections are formed by an arc (21, 22) during a switching operation. The contact parts (11, 12) of both contact systems are connected to one another and to both supply terminals (1, 2) in such a way that the current in both sections has the same direction. As a result, both arcs (21, 22) attract each other and displacement of the arcs relative to one another is prevented. Both arcs run synchronously into the arc extinction chamber (28, 29) with great reliability and are extinguished therein practically at the same time. The power switch is characterized by high cutout capability.
