High energy varistors from Keko Varicon
Since, as the only producer in the world, KEKO VARICON manufactures nothing but the overvoltage protection components, it is obvious that it closely observes the trends in the environment protection, the use of energy and heavy industry.
Lightning strikes and other high energy surges release very powerful flows of electricity which can damage whole buildings as well as indoor and outdoor objects if they are not protected againt these powerful overvoltages. These surges can be simulated either by 8/20 µs or 10/350 µs surge current pulses.
Features:
- Varistors for Class I, II &III according to UL 1449, IEC 61643-11
- Very low leakage currents
- Custom electrical performances
- Custom designs available for all types of SPDs
- Metallized varistor blocks or epoxy coated varistors with rigid terminals available
- Stacked varistors for improved surge current and energy capabilities
