Abstract

1492385 Protective devices SIEMENS AG 6 Nov 1974 [6 Nov 1973] 26884/74 Heading H2H A two terminal surge voltage protection device comprises a gas-filled surge voltage arrester and a voltage dependent resistor forming respective arms that are connected in parallel between two terminals wherein the gasfilled surge arrester is of the type in which two frusto-conical electrodes are inserted into respective ends of an insulating body so that their flat ends portions face each other and that they seal their respective ends, and wherein the voltage dependent resistor is a metal oxide varistor.
