... Any sensitive equipment requiring protection against lightning strikes and power crossing: ■ Ethernet, T1/E1 DESCRIPTION The SMP75 very low voltage transient surge arrestor especially designed to protect sensitive telecommunication equipment against lightning strikes and other transients. Its low voltage makes it suitable to protect low voltage transformer in T1/ E1, ethernet links without saturation of the trans- former ...
