IEC 61643-11, EN 61643-11
4p surge arrester Dimension:
4p surge arrester Application:
Application-optimized and prewired combined lightning current.
Particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g.: buildings equipped with lightning rods).

Q1: Selection of surge protector
Al: The grading of the surge protector (commonly known as lightning protection) Is assessed according to the IEC61024 subdivision lightning protection theory, which is installed at the junction of the partition. Technical requirements and functions differ. The first-stage lightning protection device is installed between the 0-1 zone, high for the flow requirement, the minimum requirement of EN 61643-11 / IEC 61643-11 is 25 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
