class 1 three phase 50ka surge arrester OBV10-I-50 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions.The voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.
+ Connectable lightning current and surge arrestors
+ High arresting capacity up to 50 kA (10/350μs) per pole
+ Combination arrestors for buildings with lightning protection system
+ Simple standard hat rail mounting
+ Labelled connections
+ Usable in systems with lightning protection class 1-4
