385v home circuit surge / surge protector appliance, lightning
protection 40KA.
Product introduction
Surge protector is used to protect the line from damage caused by
lightning induced voltage, power interference, electrostatic
discharge and so on.
The surge protector uses a multilevel protection circuit, selects
the brand components, and makes use of advanced production
technology. It has the characteristics of low flow residual
pressure, sensitive reaction, stable performance, reliable work and
so on. It is suitable for family housing, the third industry and
industry.
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.
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.
Product features
1. tunnel type terminal connection, tighter wiring is more compact.
2. cut off the line when undervoltage occurs, and reset
automatically after restoration.
3. Easy to install with small sizes
4. copper fittings have good electrical conductivity

Notice of product
1. it should match the working voltage of the protected equipment.
Please install according to the installation sketch.
2. lightning protector's input port (IN) is connected to the signal
channel, and the output terminal (OUT) is connected with the input
end of the protected device, so it can't connect with the signal.
3. 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.
4. in order to limit the inductive coupling between the protected
part after installation and the part of the unprotected equipment,
we need to make some measurements. The mutual inductance can be
reduced by the separation of the inductive source and the
sacrificial circuit, the selection of the loop angle and the
limitation of the closed loop area.
