Power system lightning protection device , electrical lightning
protection products
Product introduction
The surge protector is a lightning protection measure adopted by
Zhejiang toer Electric Co., Ltd. for the electrical system. It is
suitable for AC 50/60Hz, TT, TN-S, TN-C, IT and other power supply
systems with rated operating voltage 220V/380V, and the low voltage
power and control system of factory.
The protection of indirect lightning and direct lightning impact or
other transient overvoltage surge is mainly applicable to housing,
the third industry and industrial and mining enterprises, such as
surge protection.

Notice of product
1. data line: more than 2.5mm2; when the length of more than 0.5
meters of more than 4mm2
2. the protected equipment must have good grounding, and the
grounding impedance value is according to the relevant standard.
3. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
4. 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.
Product features
1. using the latest arc extinguishing technology to avoid fire
completely
2. with the power status indication, indicating the working state
of surge protector.
3. new technology, high energy, gap discharge electrode N-PE.
4. fastening slideway buckle design is very difficult to fall off
Working principle of product
Under normal working condition, the lightning protection module is
in a high resistance state. When the power supply line has
lightning invasion or operation transient overvoltage, the
lightning protection module will immediately pass through the
response speed of nanosecond level, and limit the lightning
overvoltage or transient overvoltage to the voltage range allowed
by the electrical equipment, thus protecting the normal operation
of the electronic equipment. After that, the lightning protection
module quickly returns to the high impedance state without
affecting the normal power supply of the grid.
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.
