Abstract
A surge arrester for the power supply of low voltage systems with a housing, two main electrodes which form a spark gap, an arcing chamber within the housing between the two main electrodes and with an ignition aid. When the ignition aid operates in an ignition region, ionized gas is produced which spreads in the arcing chamber so that the spark gap ignites between the two main electrodes and an arc arises in the arcing chamber. The ignition of the spark gap between the two main electrodes occurs relatively quickly after the operation of the ignition aid so that the components of the ignition aid are stressed as little as possible and are protected against damage, and at least one feed channel is formed between the ignition aid and the arcing chamber by which ionized gas produced in the ignition region flows into the arcing chamber.
