摘要
An electronic switching device for preventing operational errors caused by a high frequency, and an earth leakage breaker and method using the same can prevent the power supply from being cut off due to the high frequency by connecting primarily an N-phase switching contact due to a time difference between the N-phase switching contact and an R-phase switching contact of a power line, when the power supply is initially applied, if a leakage current over a set voltage is generated in an electric structure such as a street lamp, a traffic signal lamp or a steel pole or a submersion occurs.
