Type 1+2/Class I+II Devices for Discharging Lightning Currents and Protecting Against Voltage Surges, in Accordance with EN/IEC 61643

Product Details

OBV5-B60 series

OBV5-B60 is the series of combined Type 1+2/Class I+II devices for discharging lightning currents and protecting against voltage surges, in accordance with EN/IEC 61643.


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
