Type 2 (Class C) Protector, Suitable for Protection of Low Voltage Lines Against Lightning Strikes and Transitory Surges of Up to 40kA (8/20) in TT (TNS) Networks
Product Details

OBV5-C40 series

Type 2 (Class C) protector, suitable for protection of low voltage lines against lightning strikes and transitory surges of up to 40kA (8/20) in TT (TNS) networks. Recommended for industrial installations, distribution boards, buildings with low risk of receiving lightning strikes or fed by underground power lines.


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
