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 782 are dealt with in IEC 61439 series, as applicable; − aluminium terminals nor to terminals for connection of aluminium conductors; − use within explosive atmospheres (see IEC 60079 series); − software and firmware requirements for functional safety application (see IEC 61508-3); − cyber security aspects (see IEC 62443 series).
