Type 2 Class C Surge Protective Device for AC Power System.
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 protection device can protect electrical equipment from the impact of lightning electromagnetic pulse, induced over-voltage, transit operation, and resonance (less than 100 μs) overvoltage. In addition to the class C spd of 20KA and 25KA, we also provide 40 KA type 2 surge arrester.
