Electrical accessories - Methodology for determining the energy efficiency class of elect rical accessories(IEC 63172:2020)

This document provides a methodology for determining the energy efficiency class of electrical
accessories, to enable the system designer to determine the most efficient components for an
electrical installation, also considering all functionalities.
NOTE Functionalities are for example: wireless communication, network connectivity, timer, energy monitoring.
This methodology is based on the energy consumption, taking into account the individual
functions of the accessory.
The energy efficiency class approach contributes to the overall reduction of the energy
consumption of an electrical installation.

Petit appareillage - Méthodologie pour déterminer la classe d'efficacité énergétique du petit appareillage (IEC 63172:2020)

L'IEC 63172:2020 fournit une méthodologie permettant de déterminer la classe d'efficacité énergétique du petit appareillage, afin de permettre au concepteur du système de déterminer les composants les plus efficaces pour une installation électrique en prenant également en considération l'ensemble des fonctionnalités. Cette méthodologie est fondée sur la consommation d'énergie et prend en compte les fonctions individuelles de l'appareil. L'approche par la classe d'efficacité énergétique contribue à la réduction générale de la consommation d'énergie d'une installation électrique.

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.

International Standard IEC 63172 has been prepared by IEC technical committee 23: Electrical

accessories.
The text of this International Standard is based on the following documents:

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be

INTRODUCTION

The electric energy efficiency of homes and buildings is continuously increasing by reducing

the electric energy consumption of products. For example, changing from traditional

incandescent lighting to LED lighting.

Specific electrical systems and accessories, for example home and building electronic systems

(HBES) / building automation control systems (BACS), individual sensors, actors, actuators,

dimmers and load shedding equipment (LSE), can contribute to additional energy savings.

Additional savings can also be achieved by managing and monitoring electrical energy use,

depending on time, occupancy, inputs and needs from the grid.

HBES/BACS contribute to greater energy savings than the energy they consume to perform this

task. However, as every watt counts, it is necessary to optimize their own energy consumption

for given functionalities.

In the case of devices with more functionality (e.g. multi-channel switch actuators, control boxes,

etc.), this document provides a methodology for determining the energy efficiency class of

accessories based on the consumption of each function and their percentage of use. It aims to

enable the system designer to determine the most efficient system considering the increasing

user demand for additional functionalities.
