Protective circuits are multi-stage, cascaded protective devices. The individual protection stages may consist of spark gaps, varistors, semiconductor elements and gas discharge tubes (see energy coordination).

The protective conductor current is the current which flows through the PE connection when the surge protective device is connected to the maximum continuous operating voltage UC , according to the installation instructions and without loadside consumers.
