Which power lightning arrester is more suitable for home use

Which power surge protector is more suitable for home use? How to choose the right product for home surge protector?
If you are not familiar with the three-level lightning protection of the building power distribution system, you can refer to the previous article: Three-level lightning protection scheme for power supply

The lightning protection of the power supply system is divided into multi-level lightning protection. The power distribution system of a building is used for lightning protection: the main incoming cabinet is the first level of lightning protection, the floor power distribution cabinet is the second level of lightning protection, and the household power distribution box is the first level of lightning protection. Three-level lightning protection.
Households are all single-phase electrical systems, so the third-level single-phase surge protector can be selected for the home lightning surge protector.

There is no such thing as a lot of kW for a lightning arrester, because in normal state, there is no current passing through it, and if there is no current, it will not do work, so there is not much KW!
The main parameters of the surge arrester are also indicated by the voltage protection level and the discharge current. Generally, the T2 level surge arrester for household use has a voltage protection level of not more than 1.5KV, preferably 1.2KV; the discharge current can be 10-20KA;

It is still necessary to install a home lightning protector. The price of a lightning protector ranges from tens to hundreds, which can protect the power lines and equipment in the home. In contrast, if the electrical appliances are damaged by lightning strikes, it is thousands of dollars. There are all things, then the small loses the big.
