Product Details
The lightning protection module(surge protector)is mainly suitable for electrical lines with a50Hz(or 60Hz) impact current capacity not greater than(200kA),limiting the transient overvoltage amplitude,absorbing, consuming or discharging surge current energy,so that in When the overvoltage category is higher,the protected electrical components can be converted from one overvoltage category to another lower overvoltage category.It is suitable for household and similar places of electrical appliances in the line induction lightning strike overvoltage, overvoltage plays a protective role.
Normal usage conditions
1.The ambient temperature is-40°ºC~+80ºC.
2.The altitude does not exceed 2000m.
3.The relative temperature is not greater than 90%(25ºC).
4.The installation method is compatible with TH35mmwide guide rail.
5.Applicable ground pump flow"IT""TTTS.TN-NS".
6.The inclination with the vertical plane shallnotexceed5°
7.Places without impact,vibration or shaking.
8.1.There is no risk of explosion in the medium,and there is no gas and dust in the medium
that can corrode metal and damage insulation.

Main structure and working principle
In a three phase four-wire system,protectors are connected between the three phase lines and one neutral line to ground.Under normal circumstances,the protector is in a high resistance state.When the power grid encounters surge overvoltage due to lightning strikes or other reasons,the protector will immediately conduct quickly within nanoseconds and introduce the surge overvoltage into the earth,thus protecting the electrical equipment on the grid. When the surge voltage passes through the protector and disappears,the protector returns to a high resistance state,thus not affecting the normal operation of the power grid.The electrical schematic diagram of the surge protector is shown in the figure below.
