Low Voltage Surge Protective Device Type 2 4P Uc 385V Poles For Power Supply

Product Description

AC 40kA 1P 2P 3P 4P(+NPE) Type 2 Surge Protection for Power supplies
OBV5-C40
The surge arrestors OBV5-C40-LT 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.

Necessity of lightning protection detection:
1.lightning protection detection surge protector can resist lightning disasters and ensure life safety.
The damage of lightning to buildings can only be avoided through lightning protection devices. Lightning directly hits buildings or equipment exposed to the air, and various overhead metal cables will cause equipment damage, and even more serious fires will cause people to bring damage to the equipment. Unnecessary property damage. Professional lightning protection testing companies can do professional lightning protection. The lightning protection testing is to check whether the installed lightning protection devices or structural equipment are reasonable, whether the protection conditions meet the requirements, and whether the electrical safety meets the standards. If it fails to meet the requirements, the lightning protection inspection company will promptly put forward corresponding rectification opinions;
 
2.Lightning protection device test results meet national standards.
The detection results of lightning protection devices of well-known domestic lightning protection inspection companies are based on the standards of the national professional departments, and the lightning protection inspection companies also use the relevant lightning protection technical standards and standards of the country and various departments as the measurement index. Professional lightning protection testing companies also have relatively more testing content. A series of lightning protection testing software and equipment involved in the detection process can objectively make standard judgments on lightning protection work, so the accuracy of the data results is also higher;
 
How to choose a suitable power arrester:
　　 When choosing lightning arresters to protect different types of equipment in an area, the following factors should be considered comprehensively:
●The intensity of thunderstorms in the area, the number of days of thunderstorms and the parameters of the maximum discharge current and the probability of occurrence;
●The value of the protected equipment;
●The level of impact resistance of the protected equipment;
●The social importance of protected equipment;
●Determine the power surge arrester with different protection voltage UP and discharge current;
