KNFX380-40 Three Phase Power Supply Lightning Protection Box
Three phase power supply lightning protection box is suitable for three-phase power supply system, protection
class C power protection products belongs to SPD, parallel connection in the power supply system, To prevent
the outside (lightning, electromagnetic interference etc.) or the system (system of stretch closing effect, inductive
and capacitive load start and stop etc.) induced by pulsed surge and instantaneous over voltage damage to the
power supply system equipment.
This product has large discharge reserve energy, up to a maximum of 80kA (8/20μs), a low level of protection,
safe and reliable, reasonable structure, convenient installation, and design a Kevin connection mode, can guarantee
the best protective effects to the power system.
Working Principle
This product uses the popular protection devices switch type of protection components(which presents a high
impedance in the absence of surge and overvoltage once the selected surge and overvoltage protection devices
reached the value, and the emergence of a low impedance) and the limit of the most commonly(which presents
high impedance, in the absence of surge and overvoltage when the selected surge and overvoltage protection
devices once reached values, and started and will increase with the surge and overvoltage, the impedance will
continue to decrease) used on the nonlinear characteristics of surge and overvoltage when working, coupled
with its fast corresponding characteristics will surge, timely discharge to the earth, and the voltage clamp in the
equipment can withstand the voltage range.

Installation and Maintenance
1.The installation mode of the product is wall mount, and is installed with the corresponding accessories, during
the actual installation according to the concrete circumstance to installation.
2.This product uses the black aluminum alloy shell, before the installation, check if the products and accessories
are complete and fully intact. Fix The products ,according to the wiring diagram of the power line and the
ground wire connected properly, check after electrifying, normal work, the indicator light is normal green.
3.For the normal work of the lighting protection gate, grounding is very important, the grounding wire cross-
sectional area is no less than 16mm ², and as short as possible.
4.The product needs no special maintenance, but it is on position for a long- term period, so we should assign
someone to inspect regularly, especially in the season of thunderstorms. Once stuck by lightning, inspect it
immediately.
5.This product has set up a working indicating light, ground light, malfunction indicator light and remote alarm.
When working properly, the working indicator light green light, ground indicator light green light, when the
protection device of each phase after a fault occurs, the fault indicator light red light, at the same time, remote
signal alarm output ports normally opened switch quantity signal.
6.When working, the internal components is with 380V alternating current, must Caution!
