Power lightning protection module, primary power protection, 380V
protector 1p40KA.
Product introduction
The surge protector is designed according to the standard of IEO
and GB. It is applied to power supply protection of equipment
system in areas with high lightning risk. It can prevent all kinds
of surge currents directly hitting lightning. It can be applied to
single-phase and three-phase power supply lines and modular design
through different combinations.
Working principle of product
During the operation of the equipment, the lightning arrester will
play a protective role once the abnormal voltage occurs.
When the protected device is running under normal working voltage,
the arrester will not work, and it will be regarded as a circuit
for the ground. Once the high voltage is present and the insulation
of the protected equipment is endangered, the lightning arrester
acts immediately and leads the high voltage impact current to the
earth, thus limiting the amplitude of the voltage and protecting
the insulation of the electrical equipment. When the overvoltage is
gone, the arrester is restored to its original state quickly, so
that the system can supply electricity normally.
The main function of the lightning arrester is to reduce the
voltage value of the protected equipment through the action of
parallel discharge gap or nonlinear resistance, and to reduce the
voltage value of the protected equipment, so as to protect the
power equipment.
Notice of product
1. when installing, pay attention to the cable entering and leaving
the surge protector. The cables should be separated to avoid the
two coupling of surge.
2. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
3. lightning arresters are connected in series between protected
equipment
Product features
1. multi-functional overvoltage protection, lightning and
overpressure are no longer afraid of disasters.
2. limit the precision of the voltage to say how much!
3. self protection voltage is more than self protection, automatic
disconnection and recovery.

Product Installation
With 35mm standard DIN-rail mounting, connecting copper stranded
conductor is 2.5~35mm²
At front of spd each pole must be setted protection---used fuse or
miniature circuit breaker lightning current SPD protection,after
SPD breakdown to short circuit protection.
SPD install on protected line(equipment) to the front and connected
to the supply line. A class products install in the building
home-entry line hold larger surge current total distribution box.
B, C class products most install on the floor distribution box, D
class products close to the front-end equipment that smaller surge
current, smaller residual voltage place.
