Introduction to LV switchgear. National and international standards define the manner in which electric circuits of LV installations must be realized, and the capabilities and limitations of the various switching devices which are collectively referred to .In North America, low voltage typically refers to electrical systems operating between 50 and 600 volts. In contrast, in the EU, the term "LV" is defined by the Low Voltage Directive (LVD), which covers electrical equipment designed for use with a voltage rating of 50 to 1000 volts for alternating current (AC) and 75 to 1500 volts for direct .
