The highest protection against transient overvoltages for power supply lines at the point they enter the building. OBV10-I-25 series provide protection even against direct lightning strikes. Tested and certified with lightning impulse current, 25kA, 10/350μs wave.
lightning current arrestors OBV10-I-25 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 25 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
