A surge protective system has a plinth for wiring and is connected between a plurality of line side wires and a ground wire. A plurality of surge protective devices (SPDs) and one surge detector are disposed in parallel, and is detachably fitted into and installed in the plinth. The plinth has a wiring bracket for connecting the plurality of SPDs and the one surge detector. When a lightning surge current i penetrates into the surge protective system from the line side wires, the lightning surge current i flows to the surge detector through the SPDs of the surge protective system, a first plinth contact part in the wiring bracket, a connection part, and a second plinth contact part. The lightning surge current i flowing to the surge detector is discharged to the ground (GND) through the ground wire. According to the configuration above, the surge protective system is capable of being compact and being stored in a distribution frame having a small space. |
