Product Description

Wholesale 40ka , 380v Metal Oxide Gapl Type 2 Surge Arrester / Protector

 
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.

● For using in the lightning protection zones concept at boundary 1-2.
 
Installation requirements for power supply lightning protection products
a. The power lightning protection product has a parallel installation method to the ground. When parallel installation is adopted, the length of the wire connecting the lightning protection product must be less than 0.5m.
b. There are also series installations for power supply lightning protection products, but the series installation is prone to temperature rise problems and potential safety hazards. Generally, the first-level power supply lightning protection products are not recommended to be installed in series.
c. The fuse (fuse) or circuit breaker (circuit breaker) must be installed in series before the lightning protection product of the power supply to prevent possible short-circuit to ground when the lightning protection product fails.
d. Requirements for connecting wires of power supply lightning protection products:
 

Protection levelTypes of SPDConductor cross-sectional area (mm square)
Connect the phase wiresGround wire
First levelVoltage switch type1625
Second levelPressure-limiting1016
Last StagePressure-limiting610

 
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;

Key parameters of power surge protector:
 
●Maximum continuous withstand voltage Uc (rms):
means that the arrester can work continuously at this voltage value without affecting its parameters as the arrester. Uc is non-linearly proportional to the protection voltage Up.
● Maximum discharge current Imax:
Use 8/20μs wave surge arrester once, the maximum discharge current that can withstand. It can be selected according to the local thunderstorm intensity Ng (or the average annual thunderstorm day Td) and environmental factors.
●Residual voltage Ur and protection voltage Up
Residual voltage Ur: Refers to the residual voltage value under the rated discharge current In.
Protection voltage Up: The protection voltage Up is related to the Uc voltage and Ur. According to the characteristics of the zinc oxide varistor, when the Uc value of the selected varistor is high, its Up and Ur will increase accordingly, such as when the discharge current is 10kA (8/20μs):
Uc=275V Ur (10kA, 8/20μs) ≤1200V
Uc=385V Ur (10kA, 8/20μs) ≤1600V
Uc=440V Ur (10kA, 8/20μs) ≤1800V
