Simplified selection procedure

discharge class IEC classifies arresters by their nominal discharge current. For 10 and 20 kA arres-ters, they are also classified by energy capa-bility expressed as line discharge class (2 to 5) verified in a long duration current test and a switching surge operating duty test. In the latter, the arrester is subjected to two
