Surge arrester B88069X1193T303
2-electrode arrester S20-A470X
Description
The S20-series has been especially designed to meet data transmission protection requirements.
The optimized design features a high level of protection against fast rising transients usually caused
by lightning disturbances. For use in high frequency data lines, the series offers ultra low
capacitances and shows only marginally signal losses up to high frequencies. The devices are
extremely reliable and are able to withstand high surge currents without destruction.
Features Applications
