This document applies, when required by the relevant product standard, to low-voltage switchgear and controlgear hereinafter referred to as \'equipment\' or “device” and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC.
This document states the general rules and common safety requirements for low-voltage switchgear and controlgear, including:
definitions;
characteristics;
information supplied with the equipment;
normal service, mounting and transport conditions, decommissioning and dismantling;
constructional and performance requirements;
verification of characteristics and performance;
energy efficiency aspects (see Annex V);
environmental aspects.
This document does not apply to:
low-voltage switchgear and controlgear assemblies which are dealt with in IEC 61439 series, as applicable;
terminals for connection of aluminium conductors;
NOTE Terminals for aluminium conductors are under consideration for the next revision.
use within explosive atmospheres (see IEC 60079 series);
