LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES –
Part 7: Assemblies for specific applications such as marinas, camping
sites, market squares, electric vehicle charging stations
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC 61439-7 has been prepared by subcommittee 121B: Low-voltage switchgear and

controlgear assemblies, of IEC technical committee 121: Switchgear and controlgear and their

assemblies for low voltage.

This second edition cancels and replaces the first edition published in 2018. It constitutes a

technical revision.

This edition includes the following changes with respect to the previous technical specification:

a) a general editorial review and a technical revision.

and conversion of electric energy, and for the control of electric energy consuming

equipment;

• assemblies operated by ordinary persons (e.g. to plug and unplug of electrical equipment);

• assemblies intended to be installed and used in market squares, marinas, camping sites

and other similar sites accessible to the public including temporary installations;

• assemblies intended for charging stations for electric vehicles (AEVCS) for Mode 3 and

Mode 4. They are designed to integrate the functionality and additional requirements for

electric vehicle conductive charging systems according to IEC 61851-1:2017.

NOTE 1 Throughout this document, the terms AMHS (see 3.1.701), ACCS (see 3.1.702), AMPS (see 3.1.703),

AEVCS (see 3.1.704) are used for low-voltage switchgear and controlgear assemblies intended for use respectively

This document applies to all assemblies whether they are designed, manufactured and verified

on a one-off basis or fully standardised and manufactured in quantity.

The manufacturing and/or assembling can be carried out other than by the original manufacturer

(see 3.10.1 of IEC 61439-1:2020).

This document does not apply to individual devices and self-contained components such as

circuit breakers, fuse switches, electronic equipment, which comply with their relevant product

5 Interface characteristics
Clause 5 of IEC 61439-1:2020 is applicable except as follows.
5.1 General
Replacement:

The characteristics of the assembly shall ensure compatibility with the ratings of the circuits to

which it is connected and the installation conditions and shall be declared by the assembly

manufacturer using the criteria identified in 5.2 to 5.6, 5.701 and 5.702.

The specification schedule detailed in the informative Annex AA is intended to help the user

and the assembly manufacturer to meet this objective, whether the user:

• selects catalogue products, the characteristics of which meet their needs, and the

requirements of this document; and/or,
• makes a specific agreement with the manufacturer.
5.4 Rated diversity factor (RDF)
Addition:

In the absence of an agreement between the assembly manufacturer and the user concerning

the actual load currents, the assumed loading of the outgoing circuits of AMHS, ACCS, AMPS

assembly or group of outgoing circuits can be based on the values in Table 701.

The assumed load current is the rated current of the protective device I as required by the

user, multiplied with the loading factor of Table 701.

Table 701 does not apply for AEVCS. For AECVS it is assumed that all circuits can be loaded

continuously and simultaneously. Therefore, the assumed loading factor of the outgoing circuits

shall be taken as equal to 1 and can be reduced if a load control is available.

NOTE Values in Table 701 represent minimum values which are reached or exceeded in tests.

5.6 Other characteristics
