Low-voltage switchgear and controlgear — Part 1: General rules

Note: The standard development activty of this Notice of Intent (originally published on August 20, 2024) was updated by the responsible SDO on October 8, 2024.

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);  
− software and firmware requirements for functional safety application (see IEC 61508-3);  
− cyber security aspects (see IEC 62443 series).
