Beschreibung
Zusammenfassung:	The invention relates to an encapsulated spark-gap based surge voltage protector (2) having two, at least partially opposing, main electrodes (4, 5) and at least one trigger or auxiliary starting electrode (3) and an arc chamber (6) arranged between the main electrodes. According to the invention, the arc chamber is dominated by an insert part which comprises internally at least one gap-like arc channel (7), wherein the gap length of which is a multiple of the gap width or the gap diameter and the insert part consists at least partially of a gas-emitting material in such a manner that gas is emitted into the arc channel.
