Abstract
The invention relates to an encapsulated surge protection device capable of carrying lightning currents and limiting follow currents and comprising at least one spark gap, which has in each case at least two main electrodes and one auxiliary electrode, which is connected to a starting device for triggering in the event of transient surges. The invention provides a second starting device which is independent of the first starting device and which can activate the spark gap without the need for the presence of surges or pulse currents on the basis of the presence of a minimum voltage between the main electrodes of the spark gap.
