Industrial lightning surge protector, surge arrester, 275V 385V
420V surge protector
Brief introduction
The power supply surge protector, also known as the power supply
lightning protection device, is suitable for the AC 50/60HZ, the
rated voltage 220V/380V power supply system, the indirect lightning
and direct lightning impact or other instantaneous overvoltage
surge protection, suitable for home housing, the third industry and
industrial field surge protection requirements, with relative
phase, relative. The relative middle line, the middle line to the
ground and its combination protection mode.
Product features
1. core components are strictly screened, stable performance and
reliable operation.
2. advanced production process and beautiful appearance
3. self protection voltage is more than self protection, automatic
disconnection and recovery.
4. adopt the latest arc extinguishing technology to avoid fire.
Notice of product
1. when installing, pay attention to cables coming in and out of
surge protective devices, so as to avoid the two coupling of surge.
2. the protected equipment must have good grounding, and the
grounding impedance value is according to the relevant standard.
3. After correct installation, it can work steadily for a long
time. If it is found that the transmission performance of the
system is reduced or the signal is interrupted due to the cause of
surge protection, it should be maintained or replaced in time.

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.
