Application:
For protecting low voltage equipment from surge damages.
This products is especially suitable for application in the A grade lightning protection in high risk area of lightning strike.
Suitable for indoor operation, if installed in the outdoor, must be equipped with waterproof shell.
It is mainly used for the first stage of lightning surge overvoltage protection in AC distribution system.
Used to protect electrical and electronic equipment from lightning electromagnetic pulse induced voltages, operating transients and overvoltages.
Widely used in communication equipment, power, security, traffic, industrial control and other fields of power protection.
Distribution box with overhead input in building.
Installation:
Type 1 or Type 1+2 SPD (Iimp ≥ 12.5 kA) compulsory at the installation source (main distribution board in secondary buildings).
Installations more than 10 m high (apartment buildings, office buildings, hotels, etc.): type 2 SPD recommended for protecting private areas and floor distributors (communal areas) in addition to a type 1 or type 1+2 SPDs.
