FAQ

Q1: Selection of surge protector

Al: The grading of the DC Surge Protector Device T2 (commonly known as lightning protection) Is assessed according to the IEC 61643-11 / EN 61643-11 / EN 50539 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 IEC 61643-11 / EN 61643-11 / EN 50539 is 40 ka (8/20), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
