摘要： An electrical circuit for protecting an electrical load from overload current is provided. The system includes a voltage transformer configured to receive AC mains voltage from an electric mains supply and further configured to apply reduced voltage to the electrical load. A control switch comprising metal contacts is connected to the voltage transformer. The control switch is configured to facilitate application of reduced value of AC mains voltage to the electrical load. A reduced value of current flowing through the electrical load is measured by a current transformer connected in series with the electrical load. The reduced value of current is then used for estimating a current consumption value in event of AC mains voltage being directly applied to the electrical load. A control signal is then used for disconnecting the electrical circuit if the estimated current consumption value is greater than threshold overload current value.
