OBO V25-B / 3 + NPE 



 Product Description 
 List of V 25-B properties with the advantages 
 With a flag pin, easy to install and can cope with the impact of frequent surge current 
 Enhanced protection, the smaller the overall space used in the building where only the total power distribution cabinet to install a protector 
 Pluggable protection module components can be hot plug replacement of damaged 
 Protection within the connection base, the base 1-4 and the number of modules easy to install 
 Thermal circuit breakers and window installation instructions 
 To protect the working conditions at a glance 
 NPE spark gap with the module using a wide range of protection (for TN, TT and IT network), 
 Structure is more secure 
 V 25-B/NPE with reverse protection to ensure the protection module into a simple, professional installation
