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.

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!
