Application:

Main structure and working principle:

In a three-phase four-wire system, three phase lines and a zero line are protected between the ground wire and the three phase lines. Protector is in a state of high resistance under normal circumstances,When the power grid surges due to lightning strikes or other causes, the protector will immediately switch on within nanosecond time and bring the surge overvoltage into the earth, to protect electrical equipment on the power grid. when the surge voltage through the protector, and disappeared , the protector to change to a high resistance state, Thus does not affect the normal operation of the power grid.

Character

1. Class B lightning current SPD protection for equipotential connection during lightning strike

2. Install at the junction of LPZOA or LPZOB and LPZ1
3. Usually installed in the incoming low voltage main distribution cabinet
4. The protector is mounted on a standard 35MM rail
5. The protector is connected by copper wire of 6-35mm2
6. The ground wire should be more than 6MM2 of two-color wire
7. In order to prevent the failure of the surge protector from affecting the normal operation of the power grid, the protector connected to the L line shall be connected in series with a backup protector or fuse of 63A or above
