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.
