OBO V25-B+C/3+NPE-280

The surge arrestors V25 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 voltage-limiting high-performance zinc oxide varistor provides several benefits. An extremely short response time, a low protection level and high current leakage capability with long service life. In addition, the devices do not produce any line follow current. If circumstances are uncertain and there is a risk of fire from overloads, the cut-off unit disconnects the arrestor safely from the mains.
