This IOGP Specification details requirements for the design, materials, fabrication, inspection and testing of low voltage power switchgear and controlgear assemblies (PSC Assemblies). This Specification amends and supplements IEC 61439-1 Edition 2.0: 2011 and IEC 61439-2 Edition 2.0: 2011, referring sequentially to the same clause numbers.

Certification of distribution assemblies is defined by international standard IEC 61439-1. This standard provides common rules that are recognized worldwide. Compliance with the standard is certified, depending on the country or market, by a declaration of the panel builder, the design office, the installer or the user.

IEC 61439-1:2020 is available as IEC 61439-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61439-1:2020 lays down the general definitions and service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. NOTE Throughout this document, the term assembly(s) (see 3.1.1) is used for a low-voltage switchgear and controlgear assembly(s). For the purpose of determining assembly conformity, the requirements of the relevant part of the IEC 61439 series, Part 2 onwards, apply together with the cited requirements of this document. For assemblies not covered by Part 3 onward, Part 2 applies. This third edition cancels and replaces the second edition published in 2011. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) clarification that power electric converter systems, switch mode power supplies, uninterruptable power supplies and adjustable speed power drive systems are tested to their particular products standard, but when they are incorporated in assemblies the incorporation is in accordance with the IEC 61439 series of standards; b) introduction of a group rated current for circuits within a loaded assembly and the refocusing of temperature-rise verification on this new characteristic; c) addition of requirements in respect of DC; d) introduction of the concept of class I and class II assemblies regarding protection against electric shock. The contents of the corrigendum of December 2021 have been included in this copy. 2b1af7f3a8
