KNFX380-100 Three Phase Power Supply
Lightning Protection Box
KNFX380-100 is suitable for explosion-proof requirements under the three-phase power supply system,
level B protection product belongs to the power supply protection, parallel connection in the power supply line
of the power supply system , To prevent external lightning, electromagnetic interference or the system impulse
surge and transient over voltage damage to the power supply system equipment.
This product has the Discharge capacity, a low level of protection, safe and reliable, reasonable structure,
convenient installation, and design a Kevin connection mode, can guarantee the best protective effects of power
system.
Working Principle
This product uses the pressure type device protection components switch component(which presents a high
impedance, in the absence of surge and over voltage when the selected surge and over voltage protection devices
once 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 over voltage when the selected surge and over voltage
protection devices once reached values, and started and will increase with the surge and over voltage, the
impedance will continue to decrease) used on the nonlinear characteristics of surge and over voltage 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.
Work Environment
·Working temperature: -40℃~ +80℃
·Relative humidity:5% ~ 95%
·Atmospheric pressure:74.8kPa ~ 106kPa

Installation and Maintenance
1.The installation mode of the product for 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 and use of check products and
accessories are complete and fully intact. The products are fixed, according to the wiring diagram of the power
line and the ground wire connected properly, check after electrifying, normal work, the indicator light green
light
3.For the normal work of the lighting protection gate, grounding is very important, the grounding wire
cross-sectional area of not less than 25mm ², and as short as possible.
4.The product needs no special maintenance, but its long-term belongs to the power on state, so the need one of
special inspection on a regular basis, especially in the season of thunderstorms, when lightning, should be timely
inspection.
5.This product set lightning counter, work instructions and remote alarm, working properly, the working
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.While working, the internal components with 380V alternating current, must Caution!
