CTU/CTU2 Series Surge Protective Device

1. It has a very high lightning current discharge capacity;
2. Single module impulse current can reach 50kA(10/350us) at the maximum, which can prevent various currents, including the direct lightning;
3. It is applied in the primary power supply protection of a device system that has a higher lightning risk. It can be combined to use in the single-phase and three-phase lines;
4. It has advantages such as a big impulse current, low imperfection, and so on. Its core part consists of a multistage graphite gap. Reasonable design and sealed structure consists of a spark gap to ensure a safe distance inside the spark gap, which makes stable and reliable quality.
