Type 2/Class II Surge Protective Devices for Discharging Voltage Surges, in Accordance with EN/IEC 61643
Product Details

OBV5-C40 series

Type 2/Class II surge protective devices for discharging voltage surges, in accordance with EN/IEC 61643. Suitable for the second stage of protection in supply distribution panels in which Type 1 protection devices are installed upstream, or for the first stage of protection in commercial or other applications not exposed to direct strikes and with no external lightning protection system.


The surge arrestors OBV5-C40 meet the type 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 surge arrestor
+ High arresting capacity
+ Visual status display
+ Available with optional remote signalling
+ Vibration-proof
+ Simple standard hat rail mounting
+ Labelled connections
+ Voltage encoding
