Household power supply lightning protector, 385v surge protector,
40KA, primary power supply protection
Product introduction
Surge protector is a lightning protection measure developed by
Zhejiang tohr Electric Co., Ltd., which is independently developed
for electrical system.
The circuit protection is made up of a powerful diode solid state
discharge tube; basic and fine protection is based on automatic
fault protection device technology. In thermal overload, the device
moves the two ends of the original lightning protection together,
thus causing the damage of the surge.

Product features
1. leakage current is small, the response time is fast, and the
residual pressure is low
2. copper fittings have good electrical conductivity
3. fastening slideway buckle design is very difficult to fall off
4. tunnel type terminal connection, tighter wiring is more compact.
Notice of product
1. surge protector is installed with 35MM standard guide rail
2. the energy coordination of multilevel SPD
3. generally speaking, it is better to separate the protected
conductor from the non protected conductor, and it should be
separated from the ground wire. At the same time, in order to avoid
transient orthogonal coupling between power cables and
communication cables, necessary measurements should be made.
4. 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.
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.
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.
