Banner-chapter H.jpg

The three basic functions provided by low voltage switchgear for the related electrical circuit are:

  • Electrical protection
  • Isolation
  • Local or remote switching

This chapter explains these functions, describes the most common types of low voltage protection and/or control switchgear. With a special focus on circuit-breakers: their characteristics, and how to select circuit-breakers, taking into account selectivity and cascading techniques.
