Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks

IEC 61439-5:2023 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria:- used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V AC (see Figure 101 for a typical distribution network) and DC systems not exceeding 1 500 V DC;- stationary;- open type assemblies are not covered by this document;- suitable for installation in places where only skilled persons have access for their use, however, outdoor types can be installed in situations that are accessible to ordinary persons- intended for use in energy distribution in public power grids;- indoor use: assemblies for installation inside of electric power substations;- outdoor use: assemblies containing an enclosure suitable for open air installation.This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) omission of the requirement to conduct mechanical tests at -25 °C when enclosures are made of a metallic material;b) addition of assumed loading factors generation supplies and electric vehicle charging applications;c) additional dielectric tests when a PENDA is used in a distribution substation with separate HV and LV earths;d) further clarification of representative samples for design verification.The content of the corrigendum 1 (2025-02) has been included in this copy.

Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks

IEC 61439-5:2014 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network); - open ASSEMBLIES are not covered by this standard; - suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons; - for indoor or outdoor use. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the latest edition: - confirmation that tests carried out on the most onerous PENDA are deemed to verify the performance of similar and less onerous assemblies of the same general construction and rating; - more precise timing/conditions for impact force withstand tests for PENDAs designed for operation in an arctic climate; - correction of the direction of the applied force in the static load test. This publication is to be read in conjunction with IE 61439-1:2011. The contents of the corrigendum of March 2015 have been included in this copy.

Corrigendum 1 - Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
