The surge arrestors OBV1-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. In addition, the QR code printed on the arrestor allows disary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.

Tip:How can we distinguish the quality of the lightning arrester?
1. It can be seen from the reaction time: determine whether the
lightning arrester can respond in time and quickly discharge the
lightning current.
2. It can be seen from the insertion loss: this refers to the
installation of a lightning protector, the impact of this lightning
protector on the line, the smaller the better
3. It can be seen from the number of impact resistance: determines
the service life of the lightning arrester. Generally, the gas
discharge tube will not drop after being placed for a period of
time. If you want to check its quality, you can use an adjustable
high-voltage DC power supply to test .
