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.
