Abstract

IEC 62271-214:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 62271-214:2024 EXV includes the content of the references made to IEC 62271-1:2017+AMD1:2021 CSV. IEC 62271-214:2024 specifies requirements for internal arc classification of AC metal-enclosed pole-mounted switchgear and controlgear with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single-phase open terminal equipment for which an internal arc classification is assigned. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) indicators positioning update; b) neutral earthing connection of the test circuit for three-phase tests; c) general review for consistency with IEC 62271-200, Ed.3.0:2021.
