    摘要: The present invention is related to a device (1) for the detection of direct and/or alternating current to be used in the realisation of highly sensitive amperometric measuring instruments or for the detection of differential faults along with automatic switches. The inventive device comprises a magnetic core (5) disposed in such a manner to surround at least one current-carrying conductor (6). A winding (10) surrounds the magnetic core (5) and is electrically connected to an electrical resistance (60). A voltage source (40) generates a drive voltage (Vexcit) which permits the circulation of a pick-up current (Iexcit) in the said winding (10) and in the said core (5). Amplification means (20) are used to detect the voltage (Vsense) at the terminals of the resistance (60) in order to generate a first signal (Vampl) which is representative of the above defined current (lexcit). The inventive device (1) also comprises a feedback adjustment circuit block (70) which acquires the first input signal (Vampl) in order to generate a second signal which inverts the said drive voltage (Vexcit) when the pick-up current (Iexcit) reaches preset values.

    摘要: An electrical device for protection against residual currents, which comprises an insulating casing having a rear wall, a front wall, a bottom wall, a top wall, and two side walls. Inside said casing there are: a residual-current sensor, which comprises a toroidal core, a primary winding and a secondary winding; and a tripping relay, having a containment box, from a wall of which there protrude a first pin and a second pin designed to enable operative connection of the relay with the current sensor via circuit-connection means positioned between them. Said connection means comprise a first substantially rigid body, on which there are defined two distinct electrically conductive paths; the first conductive path has a first end connected to the secondary winding and a second free end designed to be connected operatively to said first pin, and the second path has a third end connected to the secondary winding and a fourth free end designed to be connected to said second pin, said first and second pins and said second and fourth free ends being located in a spatial position that is pre-defined with respect to one of said walls of the casing.

    摘要: An electronic earth leakage current device for a low-voltage power line, comprising: a moving contact and a fixed contact which can be mutually coupled/uncoupled; 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; first electronic means which are electrically connected to the first sensor means in order to generate, on the basis of an 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 the electric tripping signal, the separation of the moving contact from the fixed contact. Its particularity consists of the fact that it comprises second electronic means for controlling, depending on the electric signal which is indicative of the value of the earth leakage current, signaling means which are suitable to provide the user with information regarding the value of the detected earth leakage current.
