# Current Interruption Basics

Chapter

## Abstract

In this chapter, the principle of current interruption in power switching devices with mechanically separating contacts is presented. The interruption is associated with initiation and extinction of a switching arc. First, a qualitative description of current interruption in power networks with various load types is given, and important parameters and concepts are introduced.
