heavy duty AC Surge Protection Device (SPD) for high exposure applications such as direct lightning strikes, capacitor bank switching and large inductive loads. The OBV7 series is a single pole device that incorporated a multi-varistor circuit. It offers unmatched mechanical flexibility and can be installed in various worldwide system configurations with voltages up to 440V AC.
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
