Lei Zhenzi 220B-B / 2 


 Three-phase AC power SPD 220B-B / 2 

 OA-1 region for the Lightning zone, to prevent over-voltage low-voltage equipment by the interference. 
 - B-level overvoltage protection 
 - Nominal discharge current (40KA), fast response time (≤ 25ns) 
 - Lightning protection modules using standard components, installation and maintenance is simple, s easy 
 - Protection module overheating, over-flow control of security from the device 
 - Reflected by the failure of the window displays a red flag
