93 FOREWORD
94 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
95 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
96 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
97 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
98 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
99 preparation is entrusted to technical committees; any IEC National Committee interested in the subject de alt with
100 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
101 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
102 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
103 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
104 consensus of opinion on the relevant subjects since each technical committee has representation from all
105 interested IEC National Committees.
106 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
107 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
108 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
109 misinterpretation by any end user.
110 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
111 transparently to the maximum extent possible in their national and regional publications. Any divergence between
112 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
113 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
114 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
115 services carried out by independent certification bodies.
116 6) All users should ensure that they have the latest edition of this publication.
117 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
118 members of its technical committees and IEC National Committees for any personal injury, property damage or
119 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
120 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
121 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
122 indispensable for the correct application of this publication.
123 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
124 rights. IEC shall not be held responsible for identifying any or all such patent rights.
125 International Standard IEC 62271-214 has been prepared by subcommittee 17C Assemblies,
126 of IEC technical committee 17: Switchgear and controlgear.
127 This second edition cancels and replaces the first edition published in 2019. This edition
128 constitutes a technical revision.
129
130 This edition includes the following significant technical changes with respect to the previous
131 edition:
132 - indicators positioning update
133 - neutral earthing connection of the test circuit for three-phase tests
134 - general review for consistency with IEC 62271-200 Ed.3.0 already published

140 Full information on the voting for the approval of this International Standard can be found in the
141 report on voting indicated in the above table.
142 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
143 This standard shall be read in conjunction with IEC 62271-1, second edition, published in 2017,
144 to which it refers, and which is applicable unless otherwise specified in this standard. In order
145 to simplify the indication of corresponding requirements, the same numbering of clauses and
146 subclauses is used as in IEC 62271-1. Amendments to these clauses and subclauses are given
147 under the same references whilst additional subclauses are numbered from 101. Any clause
148 with the term “Not Applicable” relates to the clause not being relevant to IEC 62271-214 and
149 does not infer the clause is or is not relevant for its applicable switchgear standard.
150 A list of all parts of the IEC 62271 series, published under the general title High-voltage
151 switchgear and controlgear, can be found on the IEC website.
152 The committee has decided that the contents of this document will remain unchanged until the
153 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
154 the specific document. At this date, the document will be
155 • reconfirmed,

161 INTRODUCTION
162 IEC 62271-214 has been developed due to the requirement to remove IAC Type C designated
163 pole-mounted switchgear from IEC 62271-200. IEC 62271-214 is to be considered independent
164 of IEC 62271-200, however it is still related to other product standards of the IEC 62271 series.
165 Only open terminal pole-mounted switchgear has been considered within this document.
166 This equipment relates to operation in three-phase, two-phase and single-phase systems.

172 switchgear and controlgear for rated voltages above 1 kV and up to

174
175
176
177 1 Scope
178 This part of IEC 62271 specifies requirements for internal arc classification of metal-enclosed
179 pole-mounted AC switchgear installations with rated voltages above 1 kV and up to and
180 including 52 kV with service frequencies up to and including 60 Hz. This document is applicable
181 to three-phase, two-phase and single-phase open terminal equipment. Enclosures may include
182 fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.
183 NOTE For the use of this document high-voltage (IEC 60050-601:1985, 601-01-27) is the rated voltage above 1 000
184 V. However, medium voltage (IEC 60050-601:1985, 601-01-28) is commonly used for distribution systems with
185 voltages above 1 kV and generally applied up to and including 52 kV; refer to [1] of the Bibliography.
186 This document does not preclude that other equipment may be included in the same enclosure.
187 In such a case, any possible influence of that equipment on the switchgear and controlgear is
188 to be taken into account.
