Distribution surge surge arrester, 2P TRS4-D20 20KA surge protector
Brief introduction
Surge protector is a lightning protection measure adopted by
Zhejiang tohr Electric Co., Ltd., which is independently developed
and manufactured for electrical system. The shell is installed on
the 35mm electric rail.
The product has built-in failure detaching device. When the surge
protector overheat and breakdown, the failure exfoliation device
can automatically remove it from the power grid, and the alarm
indicator module is turned from white (normal) to red (fault).

Product features
1. core components are strictly screened, stable performance and
reliable operation.
2. using the latest arc extinguishing technology to avoid fire
completely
3. built-in overheating and temperature control circuit breaker
4. detachable assembly and pluggable convenience
Notice of product
1. installation site is not more than 2000m
2. lightning arresters are connected in series
3. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
4. 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.
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.
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.
