G20MT series voltage limiting type I voltage switching type primary power surge protectors are des-igned 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, 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.
