Low-voltage switchgear and controlgear – Part 1: General rules
|Publication Date:||1 April 2020|
|ICS Code (Low voltage switchgear and controlgear):||29.130.20|
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:
− 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);
− software and firmware requirements for functional safety application (see IEC 61508-3);
− cyber security aspects (see IEC 62443 series).
