Product Details

OBV10-I-15

heavy duty AC Surge Protection Device (SPD) for high risk, low tolerance electrical service entrance applications. The OBV10-I-15 provides protection against the direct and indirect effects of lightning and is particularly useful in a high lightning area where the risk of heavy surge current or even direct strike is high, i.e. buildings equipped with lightning rods.


lightning current arrestors OBV10-I-15 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 15 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
