ABSTRACT:
A device for protection against voltage surges in an electric power supply line includes at least two elements (1′, 3), namely a Zener diode lightning arrester (1′) fast-blow in short circuit, and a varistor (3), arranged in parallel. One of the terminals common to the two elements (1′, 3) is connected to the line to be protected, and the other common terminal is connected to earth or to a common conductor element.
