    Abstract: An electronic earth leakage current device, comprising:a moving contact and a fixed contact which can be mutually coupled/uncoupled; andfirst 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; andfirst 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; andactuation 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; andsecond electronic means, electrically connected to the second sensor means, for receiving from the second sensor means electric signals which are indicative of the operating condition of the electronic device for protection against earth leakage current and for generating an electric tripping signal depending on the electric signals.
