Type 2 AC power supply system AC module is mainly applicable to the power distribution system for class C/type 2 protection. Type 2 surge protector can protect electrical equipment from the impact of lightning electromagnetic pulse, induced over-voltage, transit operation, and resonance (less than 100 μs) overvoltage. Besides 20KA and 25KA ac spd type 2 products, we also provide 40 KA type 2 surge arrester.
