    320V Type 2 Spd , Ethernet Lightning Arrestor Din Rail Mounted

    Din-Rail Mountable 320V 40KA Lightning Arrester , Type 2 Surge Protector


    The general principle of lightning protection is:

    (1) Use external protection to direct most of the lightning current into underground discharge.

    (2) Use an overvoltage protector to block the overvoltage wave introduced along the power line, data line, and signal line (internal protection).

    (3) Use an over-voltage protector to limit the surge voltage amplitude on the protected equipment.

    (4) Use a photoelectric isolator to isolate the RS232 interface between communication and RTU to avoid electrical connection of interface equipment.


    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.

    Transient voltage surgesin lv power lines
    Transient overvoltages are voltage surges that can reach tens ofkilovolts with a duration of the order of microseconds.Despite theirshort duration, the high energy content can cause serious problemsto equipment connected to the line, from premature aging to destruction, causing disruptions to service and financial loss.Thistype of surge can have various different causes, including atmospheric lightning directly striking the external protection(lightning rods) on a building or transmission line or the associatedinduction of electromagnetic fields on metallic conductors.
    Outdoor and longer lines are the most exposed to these fields,which often receive high levels of induction.
    It is also common for non-weather phenomena, such as transformer centre switching or the disconnection of motors orother inductive loads to cause voltage spikes in adjacent lines.

    Surges in telecom andsignalling networks
    Surges tend to induce currents in allmetal conductors; not only are thepower lines affected, but so are allcables to a greater or lesser extent,depending on the distance to the focusof the surge.
    Although a lower current is induced,the effect produced is equally or moredestructive, due to the greatersensitivity of electronic equipmentconnected to communications lines(telephone, Ethernet, R, etc.).


    Importance of theground connection
    Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
    A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.

    Comprehensive protection
    An effective overvoltage protection must combine thefollowing protection systems:
    External protection (ESE lightning rods and faradization).System for protection against direct lightningstrike.These capture the lightning within the protectedarea and lead it, in a controlled manner, safely to ground. Internal protection (power frequency overvoltage andsurge protection devices). Equipment designed to protectagainst the effects of overvoltages in equipment connected to the power supply systems and/orcommunications networks.Grounding systems (grounding and insulation monitoring).Systems that allow atmospheric dischargecurrents to be dispersed into the ground. The need formonitoring the grounding system.CUAJE offers a widerange of products for each of these systems. It alsodevelops custom products, provides advice and consultingservices and the best possible aftersales service.
    What skills should lightning protectors have in the selection?
    1.Confirm power supply system
    First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
    For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
    2.Know the main parameters of the lightning arrester.
