Overview

EN IEC 61439-1:2021/FprAA:2025 (prAA) is a CLC draft amendment to the European/IEC standard for low‑voltage switchgear and controlgear assemblies - Part 1: General rules. The amendment updates the general rules to reflect new scope items (notably assemblies supplied from batteries or renewable energy sources) and replaces Annex J on Electromagnetic Compatibility (EMC). It is intended for manufacturers, test laboratories, specifiers and conformity bodies involved in design, verification and CE marking of LV assemblies.

Key topics and technical requirements

• Scope update: explicit inclusion of assemblies supplied from batteries or renewable energy sources.
• EMC Annex replacement (Annex J): comprehensive EMC framework aligned with IEC/CISPR references:
  • Definitions of ports (power, signal, enclosure, functional earth) to classify interfaces for EMC purposes.
  • Environment classification: two environmental conditions defined
    • Environment A - industrial (indoor/outdoor) with high electromagnetic stress (e.g., heavy loads, ISM apparatus).
    • Environment B - residential, commercial and light‑industrial (including battery-operated or DC‑powered apparatus).
  • Exemptions from EMC testing: conditions where assemblies require no further EMC tests (e.g., bespoke assemblies for fixed installations; assemblies containing only benign or a single compliant electronic device).
  • Verification requirements:
    • Assemblies not exempt must be verified for immunity and/or emissions per the Annex.
    • Immunity and emission test levels and applicable standards are specified (examples in the draft include ESD ±4 kV contact / ±8 kV air, radiated RF immunity levels, surge, EFT/burst, conducted immunity, power‑frequency magnetic field tests).
  • Performance criteria: classification of acceptable behavior during EMC tests (no change, self‑recoverable degradation, temporary loss requiring operator/system reset, etc.).
• Regulatory linkage: informative Annexes (ZZA/ZZB) map the amendment to EU legislation (EMC Directive and Low Voltage Directive).

Applications and users

This document is practical for:

• Assembly manufacturers and panel builders designing LV switchgear and controlgear assemblies (including battery/renewable‑fed systems).
• Test laboratories and conformity assessors implementing EMC verification and emission testing.
• Electrical engineers and specifiers creating project requirements and installation instructions.
• Compliance and certification bodies aligning national standards with CENELEC requirements.

Related standards

• IEC/EN standards referenced for EMC testing and limits (e.g., IEC 61000‑4‑2, IEC 61000‑4‑3, IEC 61000‑4‑4, IEC 61000‑4‑5, IEC 61000‑6‑1/2/3/4) - see Annex J for specific cross‑references.

Keywords: EN IEC 61439-1:2021, low‑voltage switchgear, controlgear assemblies, EMC, electromagnetic compatibility, environment A, environment B, immunity tests, emission tests, batteries, renewable energy, CENELEC.

63 J.9.4 Requirements
64 J.9.4.1 General
65 Two sets of environmental conditions are considered and are referred to as environment A and environment B.
66 a) Environment A
67 Environment A relates to a power network supplied from a high or medium voltage transformer dedicated
68 to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in
69 proximity to industrial locations, as described below.
70 The environments encompassed are industrial, both indoor and outdoor.
71 Industrial locations are characterized by the existence of one or more of the following examples:
72 — industrial, scientific and medical (ISM) apparatus (as defined in CISPR 11:2015 );
73 — heavy inductive or capacitive loads are frequently switched;
74 — currents and associated magnetic fields are high.
75 NOTE 1 The generic EMC standards for electrical and electronic equipment in industrial environments are
76 IEC 61000-6 2:2016 regarding immunity and IEC 61000-6-4:2018 regarding emission. The EMC requirements for
77 assemblies in industrial environments given in this document are in line with these standards.
78 b) Environment B
79 Environment B relates to low-voltage public mains networks or apparatus connected to a dedicated DC
80 source which is intended to interface between the apparatus and the low-voltage public mains network. It
81 applies also to apparatus which is battery-operated or is powered by a non-public, but non-industrial,
82 low-voltage power distribution system.
83 The environments encompassed are residential, commercial and light-industrial locations, both indoors and
84 outdoors. The following list, although not comprehensive, gives an indication of locations which are
85 included:
86 — residential properties, for example houses, apartments;
87 — retail outlets, for example shops, supermarkets;
88 — business premises, for example offices, banks;
89 — areas of public entertainment, for example cinemas, public bars, dance halls;
90 — outdoor locations, for example petrol stations, car parks, amusement and sports centres;
91 — light-industrial locations, for example workshops, laboratories, service centres.

94 NOTE 2 The generic EMC standards for electrical and electronic equipment in residential, commercial and light-industrial
95 environments are IEC 61000-6-1:2016 regarding immunity and IEC 61000-6-3:2006 regarding emission. The EMC
96 requirements for assemblies in industrial environments given in this document are in line with these standards.
97 The environmental condition (environment A and/or environment B) for which the assembly is suitable shall be
98 stated by the assembly manufacturer.

103 assembly is not otherwise available on the market;
104 — the incorporated devices and components are in conformance with the requirements for EMC for the
105 stated environment (see J.9.4.1) as required by the product standard;
106 — the internal installation and wiring is carried out in accordance with the devices and components
107 specifications and applying good engineering practices (arrangement with regard to mutual influences,
108 cable, screening, earthing, etc.).
109 b) No further EMC immunity or emission tests are required on assemblies if one of the following conditions is
110 fulfilled:
111 — the assembly is only incorporating benign devices in terms of electromagnetic compatibility e.g. wires,
112 busbars, terminals, electromechanical devices, or electronic devices in which all components are
113 passive for example diodes, resistors, varistors, capacitors, surge suppressors, inductors, RCDs
114 incorporating electronics but without continuously operating oscillator
115 — the assembly is incorporating one single electronic device in addition to benign and/or passive devices
116 in respect of electromagnetic compatibility. The single electronic device shall be in conformance with
117 its own product standard.
118 J.9.4.3 Assemblies to be verified for EMC immunity
119 Assemblies not covered by J.9.4.2 shall be verified in respect of immunity in accordance with J.10.12.2 unless
120 the incorporated devices and components are in conformance with the requirements for EMC for the stated
121 environment (see J.9.4.1) as required by the relevant product standard and the internal installation and wiring
122 is carried out in accordance with the devices and components specifications and applying good engineering
123 practices (arrangement with regard to mutual influences, cable, screening, earthing, etc.).
