prEN IEC 60947-1:2026

This document applies 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, when required by the relevant product standard or in case no relevant product standard is available.
NOTE In this document, an “assembly” means the combination of switching or controlling devices with associated control, measuring, protective or regulating equipment.
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, including electromagnetic compatibility (EMC), safety measures against electric shock, fire hazard, mechanical hazard and radiocommunication, if applicable;
– use of aluminium conductors (Annex B);
– verification of characteristics and performance;
This document does not apply to:
– low-voltage switchgear and controlgear assemblies according to IEC 61439 series;
– use within explosive atmospheres (see IEC 60079 series)
