Lightning current discharge arrester with spark gap for the use in three-phase TT and TN-S systems.They provide extremely high discharge cappabilities with at the same time very low protection levels and they also do not need any damageable internal or external electronic trigger.
lightning current arrestors 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
