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 sixth edition cancels and replaces the fifth edition published in 2007, Amendment 1:2010 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– DC values testing improvement;
– update of EMC tests;
– Annex B deletion;
– update of requirements for environmental tests (Table Q.1);
– improvement of Annex R (new examples);
– deletion of digital input Type 2, and introduction of Type 3 in Annex S;
