220V power supply, lightning protection, 1P surge protection,
primary household power protection.
Product introduction
Surge protector lightning protector is used to protect sensitive
lines from lightning induction voltage, power grid voltage
fluctuation, electrostatic discharge and surge voltage caused by
large load start-up. It is widely used in family housing, third
industry and industrial field.

Notice of product
1. standard RJ45 interface can be conveniently connected to the
front end of the protected equipment. The grounding path should be
as short as possible, and the length should not exceed 1.5 meters.
2. lightning arresters are connected in series between protected
equipment
3. connect the grounding wire of the lightning protector with the
ground wire of the lightning protection system.
4. ambient air temperature is no more than +40 C and no less than
-5 C, and the average value of 24 hours is no more than +35 C.
Structure and Principle
SPD is a port, shocking protection, indoor-mounted installation,
voltage-limited.
SPD hold disconnector inside, when SPD breakdown failure by over
heating, the disconnector can remove from the power grid
automatically, and show indication signal. When SPD is working
properly, visible window display green, it display red when it
breakdown and disconnect.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground
protection module, apply to TN-S, TN-C-S and other power supply
system.
Working principle of product
The lightning arrester can effectively protect the power equipment.
Once the abnormal voltage appears, the lightning arrester will play
a protective role.
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.
