LV switchgear: functions and selection: Difference between revisions

Latest revision as of 13:46, 26 January 2024

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.
