This document applies to system referencing conductor switching devices (3.3) (SRCSD) for household and similar uses within a Prosumer’s electrical installations (PEI (3.1)).
The SRCSD (3.3) provides functions as described in IEC 60364-8-82:2022 [2], 82.8.2.2.4.
PEI (3.1) intended for operating by either being connected to a distribution network or disconnected from the distribution network is an islandable PEI (3.7).
Intentional disconnection from and connection to the distribution network relies on the local earthing system being switched by the SRCSD (3.3). In addition, unintentional loss of distribution network is covered.
The SRCSD (3.3) is a single pole device intended to connect one live conductor of the power system to an earthing arrangement.
In general the neutral conductor is earthed.
Switching the SRCSD (3.3) can change the local type of system earthing if types of system earthing are different in island and grid connected modes.
The system referencing conductor switching device (3.3) (SRCSD) is interlocked with the switching device for islanding (3.4) (SDFI) of a Prosumer electrical installation.
SRCSD (3.3) can be integrated in a device with other functions e.g.. with a SDFI (3.4).
NOTE 1 See also IEC 60364-8-82 [1].
This document applies to SRCSD (3.3) for rated voltages not exceeding 440 V AC with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz.
NOTE 2 SRCSD (3.3) for DC operations is under consideration.

This part of IEC 62271 provides guidance to suppliers, manufacturers, users, and waste operators of high-voltage switchgear and controlgear as well as their assemblies having a rated voltage above 1 kV AC and 1,5 kV DC, together with their associated auxiliary equipment, on environmentally conscious design, and on assessing environmental impacts when used in systems. This document also gives guidance on effective communication of environmental information throughout the entire life cycle.
This document provides guidance on the process and general aspects to select UN sustainable development goals (UN sustainable development goals (SDG)), especially those dealing with health and environmental impacts and their assessments, represented respectively by:
• SDG 3-Good Health and Well-being;
• SDG 6-Clean Water and Sanitation;
• SDG 7-Affordable and Clean Energy;
• SDG 12-Responsible Consumption and Production;
• SDG 13-Climate Action;
• SDG 14-Life Below Water;
• SDG 15-Life on Land.
This document gives guidance on the process and general aspects to implement environmentally conscious product design (ECD) principles, as given in IEC 62430, essential
for high-voltage electrical power equipment and power control equipment.
This document gives guidance on executing the life cycle assessment (LCA) based on product category rules (PCR) in accordance with IEC 63366, ISO 14040 and ISO 14044 and on applying the Type III environmental declaration in accordance with ISO 14025, both for high-voltage switchgear and controlgear. This guidance provides standardized product specific rules (PSR) summarized as follows:
1) Common rules for the LCA process describing functional units, system boundaries, life cycle inventory analysis, scenarios, environmental impact categories;
2) Common rules for communicating information about the presence of regulated substances and the materials contained in the product, according to IEC 62474;
3) Common rules for communicating information about the end-of-life treatment of the product including material efficiency.
This document does not address the environmental declaration programme, however it can be used by program operators.
This document focuses on describing the LCA process referring to the functional unit, system boundary, scenarios, etc.
Owing to variability of influencing factors, such as flows, allocations, not balanced and timestable energy mix under different programmes, equipment customization, durability related to environmental conditions, it is not possible to compare two similar high-voltage switchgear and controlgear analysed in different contexts.
This document does not address by-products from arcing which are generated in sufficiently small quantities such that their environmental impact can be neglected. Any by-product generated by arcing during the use of equipment is strongly dependent on operating conditions and cannot a priori be qualified nor quantified. However, they are not expected to be released in air and will be managed at end-of-life by a dedicated process.
EXAMPLE
During the use of high-voltage switchgear and controlgear the handlings of normally arced gas are covered by IEC 62271-4. When the volume of gaseous by-product is below 1 % of normally arced gas, it is not considered compared to the cut-off rules specified in this document. The scenarios related to the system boundary do not take into account leakages from failures except if an agreement is reached on this between user and manufacturer (see Table 7, item h).
Power transformers, low-voltage switchgear and controlgear, and the interconnections with such equipment are not covered by this document. Therefore, assemblies according to IEC 62271-202 or IEC 62271-212 comprising any of the above equipment are not within the scope of this document.
This document supports material efficiency for circular economy. However, one of the major issues related to remanufacturing is the consideration of used parts

This document covers internal arc-fault control devices, hereinafter referred to as IACD, which
are intended to:
- detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by
processing (at a minimum) the optical effect of an internal arc-fault, and
- operate mitigation device (either external or combined)
in order to minimize the effects of the internal arc-fault (see Figure 1).
For the purpose of this document the terms "light" or "optical" covers more than visible spectra.
They may cover also, for example, infrared or ultraviolet electromagnetic radiations (see
Annex D).
For combined-type IACD, this document is considered in addition to the relevant product
standard for internal arc-fault mitigation devices (IARD per IEC TS 63107:2020). Compliance
to the relevant product standard is mandatory and cannot be claimed by testing to this document
alone.
NOTE 1 Low-voltage switchgear and controlgear assemblies are usually described by IEC 61439 series.
[Figure 1]
Therefore, this document covers the following:
- internal arc-fault control device (stand-alone, multifunction or combined);
- one or more associated sensor(s) used to detect optical effect of the internal arc-fault;
- sensor(s), sensing another physical effect, to confirm the fault;
- associated or combined mitigation device.
An IACD is not intended to trigger under normal operation of low-voltage switchgear and
controlgear (i.e. absence of internal arc-fault), including normal arcing associated with
operation of disconnecting and switching devices.
This document only covers the following methods:
- optical detection of the light caused by an internal arc-fault;
- optional confirmation of internal arc-fault by line current measurement.
Many different conductive materials could be used in LV assemblies (e.g. steel, copper,
aluminium). Nevertheless, tests specified in this document are deemed to represent the most
critical and challenging conditions for arc-detection and cover all combinations of conductive
materials.
NOTE 2 Compared to other materials (e.g. steel, aluminium), copper leads to a lower optical radiation energy.
The rated voltage of the assembly in which an IACD is installed does not exceed 1 000 V AC.
Such devices are designed to be operated and maintained by skilled persons only.
This document does not cover:
- DC internal arc-fault detection and control;
- overcurrent relays;
- AFDD (arc-fault detection devices) as defined by IEC 62606;
- guidance on installation within assemblies;
NOTE 3 The integration of an IACD into an assembly is described in IEC TS 63107.
- use with additional measures needed for installation and operation within explosive
atmospheres. These are given in IEC 60079 series documents;
- requirements for embedded software and firmware design rules; for this subject, the
manufacturer is responsible for taking additional safety measures;
NOTE 4 IEC TR 63201 describes rules for firmware and embedded software development preventing errors in
software.
- cybersecurity aspects; for this subject, the manufacturer is responsible for taking additional
safety measures;
NOTE 5 See IEC TS 63208.
- mobile applications.
NOTE 6 Even when addressing internal arc-fault mitigation devices, this document does not supersede any other
relevant product standard (e.g. IEC 60947-2 or IEC 60947-9-1).
NOTE 7 DC arcing fault phenomena are under consideration. Further investigation is needed to comprehend DC
arcing phenomena and required sensing.
