An integrated surge protector assembly comprising: a casing; a surge protector, which is arranged in the casing; a miniature circuit breaker, which is arranged in the casing; a mechanical accessory, which is arranged in the casing and is connected to the surge protector and the miniature circuit breaker, wherein the mechanical accessory has a sensor configured to output a judgment signal; an electronic component connected to the miniature circuit breaker via a wire and connected to the mechanical accessory via a first transmission line to receive the judgment signal; a processing system connected to the electronic component via a second transmission line so as to receive the judgment signal from the electronic component, characterized in that the processing system is configured to determine whether the miniature circuit breaker fails; or the surge protector fails; or an upstream circuit breaker fails based on a predetermined life of the surge protector and the judgment signal, the judgment signal output by the sensor includes an opening signal generated by the failure of the miniature circuit breaker or the failure of the surge protector and a voltage signal, in the event of a loss of power to the integrated surge protector assembly, the processing system is configured to determine that the surge protector has failed when a predetermined life of the surge protector is below a predetermined threshold, in the event of a loss of power to the integrated surge protector assembly, the processing system is configured to determine that the miniature circuit breaker has failed when a predetermined life of the surge protector is not lower than a predetermined threshold, in the event of a loss of power to the integrated surge protector assembly, the processing system is configured to determine that the upstream circuit breaker failed when the sensor does not output an opening signal, the wire is configured to contact a metal piece to form an electrical connection, the metal piece passing through an opening in the electronic component together with the wire and being mounted to the casing, wherein an elastic piece is arranged between the electronic component and the metal piece, and under an action of external pressure, the electronic component and the casing move towards each other, so that the elastic piece is clamped between the electronic component and the metal piece to transmit the current in the wire to the electronic component through the metal piece, and then through the second transmission line to the processing system. a casing;
