Product Description

G20-A25 series voltage limiting type / voltage switching type primary power surge protectors are designed according to IEC and GB standards, and applied to surge protection at the first stage of the power supply system. Products are standard 35mm rail mounting methods.

G20-A25 series voltage limiting type / voltage switching type primary power surge protectors with high flow capacity, single module impact current up to 50kA (10/350 s), can prevent all kinds of lightning surge. Products are applied to the power supply of the equipment system in the higher risk area of lightning strike. The first surge protection can be used in single phase / three-phase power supply line.

Company Profile



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 GB50057 is 12.5 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.

Q2:Are you a lightning surge protectors factory or lightning surge protectors trading company?MT series Class I 25KA AC 280V 385V type1 surge protection device
