Heavy Duty AC Surge Protection Device (SPD) for High Exposure Applications Such As Direct Lightning Strikes Capacitor Bank Switching and Large inductive Loads
Product Details

OBV7 series

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
Enhanced Multi-MOV Design
