Lightning Current Combination Arrestor, Type 1+2 . MOV-based industrial SPD Solution in A Compact Housing Available in 12.5KA / Pole T1+T2 Configurations.

Product Details

OBV5-B60 series

type 1+2. MOV-based industrial SPD solution in a compact housing available in 12.5kA / pole T1+T2 configurations.


The combination lightning current and surge arrestors OBV5-B60 meet the type 1+2 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 use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary.


+ Connectable lightning current and surge arrestors
+ High arresting capacity up to 50 kA (10/350μs)
+ Visual status display
+ Available with optional remote signalling
+ Vibration-proof
+ Combination arrestors for buildings with lightning protection
+ Simple standard hat rail mounting
+ Labelled connections
+ Usable in systems with lightning protection class 3+4
