Overvoltage protection type1 + type2 surge protective device
Product introduction
Surge protector is the lightning protection measures taken by
Zhejiang tohr Electric Co., Ltd., which is independently developed
and manufactured for electrical system. It is designed according to
IEO and GB standards. 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.
In terms of material, we choose brand components and make use of
advanced production technology. It has the characteristics of large
flow capacity, low residual pressure level, sensitive reaction,
stable performance, reliable work and so on. It is widely used in
family housing, the third industry and industrial fields.
Working principle of product
The working principle of surge protector is a high resistance open
state with a low voltage, low resistance and short circuit state at
high pressure, and a combination of over voltage protection
electronic devices which can withstand hundreds of amperes and
large current in parallel on the power supply line and signal
transmission line. When encountering lightning and high voltage and
high current, it will appear short circuit immediately, and at the
same time, the total power switch will be disconnected, so that the
device will be protected.
Product features
1. it is widely used in family housing, third industry and
industrial field.
2. with the power status indication, indicating the working state
of surge protector.
3. low output residual pressure to further ensure safety

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. 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.
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.
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.
Company profile
Zhejiang Thor Electric Co., Ltd is committed to meeting the
requirements of the European Union’s Waste Electrical and
Electronic Equipment (WEEE) directive. This directive requires
producers of electrical and electronic equipment to finance the
take-back for re-use or recycling of their products placed on the
EU market after 2005.
All types and classes of our lightning and surge arresters
20KA~200KA(8/20μS) and 15KA~50KA(10/350μS) are tested and pass all
the requirements based on their class.
