1. Small size, easy to plug and replace
2. Fault resistant Y-type circuit, composed of three varistors and thermal tripping device in series
3. Double tripping protection device to provide more reliable protection
4. Large flow and quick response
5. Multi-function connection port can connect wire and bus bar
6. When the fault window pops open in green, and provides remote monitoring through the warning port


Installation Instructions:

1. Power must be cut off before installation, and live operation is strictly prohibited
2. It is suggested to connect the fuse or automatic short-circuit in series at the front end of the lightning protection module
3. Please connect according to the installation diagram, where + is the positive wire, - is the negative wire, and PE is the ground wire. Don't make a mistake. After the installation is completed, close the switch and check whether the working condition is normal
4. Insert the module in place after installation and check whether the lightning protection module works normally
5. During the use of SPD, it should be regularly monitored and checked the status of the fault display window. When the fault display window is red or the remote terminal output an alarm signal, it indicates that the lightning protection module has broken down and should be repaired or replaced in time
6. Lightning protection module should be installed in parallel, and the connecting line should be firm and reliable, and it should be short, thick and straight



It is suitable for TN-S,TN-C,TN-C-S,TT,IT active power supply system with AC 50/60HZ 380V and below. It is used for equipotential connection at the interface of LPZ0A and LPZ1 region or LPZ0B and LPZ1 region, to protect the power grid due to lightning strike or surge overvoltage.


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.



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
