IEC 60947-1:2020 applies, when required by the relevant product standard, to low-voltage switchgear and controlgear hereinafter referred to as "equipment" or \u201cdevice\u201d and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC.
\nThis document states the general rules and common safety requirements for low-voltage switchgear and controlgear, including:
\n– definitions;
\n– characteristics;
\n– information supplied with the equipment;
\n– normal service, mounting and transport conditions, decommissioning and dismantling;
\n– constructional and performance requirements;
\n– verification of characteristics and performance;
\n– energy efficiency aspects (see Annex V);
\n– environmental aspects.
\nThis sixth edition cancels and replaces the fifth edition published in 2007, Amendment 1:2010 and Amendment 2:2014. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:
\n\u2013 DC values testing improvement;
\n\u2013 update of EMC tests;
\n\u2013 Annex B deletion;
\n\u2013 update of requirements for environmental tests (Table Q.1);
\n\u2013 improvement of Annex R (new examples);
\n\u2013 deletion of digital input Type 2, and introduction of Type 3 in Annex S;
\n\u2013 example for materials declaration (Annex W);
\n\u2013 new Annex X (co-ordination between short-circuit protective devices associated in the same circuit) created.<\/p>\n","protected":false},"excerpt":{"rendered":"
