IP 20 MOV Surge Protection ,40KA Surge Arrestor For Electric System
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 .
