3Poles 80kA Surge Protection Device use at 275V power system

OBV-II80 data

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

Combine usage:

1. 4P surge protector is installed in the three phases of the TN-S system
2. 3P surge protector is installed in the three phases of TN-C or IT systems
3. 2P surge protector is installed in the single phase of the TN system
4. 1P surge protector can be freely combined and installed in various occasions
5. 3+1 and 1+1 surge protectors are used in TT distribution systems

The classification of the SPD:
1. According to the working principle divided:voltage switching type SPD, voltage limiting type SPD , voltage cobination type SPD
2. According to the use of points : power system surge protection device, signal system surge protection device
