Heavy-Duty AC Surge Protector Combines A High-energy Varistor (MOV) Network with A Gas Discharge Tube
Product Details

OBV7 series

lightning current arrestors OBV7 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 150 kA (8/20μs) 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
