Full title and description

Empty enclosures for low-voltage switchgear and controlgear assemblies — General requirements. This international standard specifies general definitions, classifications, characteristics and test requirements for empty enclosures supplied by the enclosure manufacturer for subsequent incorporation of switchgear and controlgear components (rated up to 1 000 V AC or 1 500 V DC), suitable for indoor or outdoor use.

Abstract

IEC 62208:2023 (3rd edition) provides the general technical and testing framework for empty enclosures used in low‑voltage switchgear and controlgear assemblies. It defines mechanical, environmental and electrical characteristics and specifies type and verification tests (including ingress protection IP, impact IK and structural/load tests), marking and documentation requirements. The 2023 edition updates and realigns requirements and test procedures with recent related standards, notably IEC 61439‑1:2020.

Scope

This standard applies to empty enclosures delivered by the enclosure manufacturer prior to the incorporation of switchgear and controlgear components by an assembly manufacturer. It covers enclosures intended for assemblies with rated voltages not exceeding 1 000 V AC or 1 500 V DC and is intended for general indoor or outdoor applications. It does not apply where other specific product standards already cover the enclosure (for example certain IEC product families). The 2023 edition replaces the 2011 edition and incorporates updates to align with the IEC 61439 series and revised test procedures.

Key topics and requirements

• Definitions and classification of empty enclosures for switchgear/controlgear assemblies (type, installation environment, material classes).
• Design and construction requirements: structural strength, internal clearances, mounting arrangements, lifting and transport provisions and permissible static loads.
• Protection and verification: ingress protection (IP) testing per IEC 60529, mechanical impact (IK) testing per IEC 62262, and other environmental tests appropriate to intended use.
• Electrical safety provisions: earthing/continuity requirements for Class I enclosures, insulation and barriers for Class II solutions, and measures to limit access to live parts once assembled.
• Material, corrosion and surface-treatment criteria for indoor/outdoor durability; temperature and thermal performance considerations.
• Marking, documentation and information for assembly manufacturers (ratings, IP/IK, mounting data, dimensional drawings and instructions relevant to safe and compliant final assemblies).
• Alignment of test procedures and verification methods with IEC 61439‑1:2020 and other relevant updated standards.

Typical use and users

Primary users are enclosure manufacturers, electrical assembly/manufacturing engineers, switchgear designers, compliance/test laboratories and standards committees. The standard is used to design, specify and test empty enclosures intended for low‑voltage switchgear assemblies, to ensure mechanical integrity, environmental protection and that the enclosure meets the documentation and marking needs of the final assembly manufacturer.

Related standards

IEC 62208 is intended to be used alongside product and assembly standards including the IEC 61439 series (low-voltage switchgear and controlgear assemblies), IEC 60529 (IP ratings), IEC 62262 (IK impact testing) and other specific product standards that may take precedence for particular enclosure types. The standard supersedes earlier editions (EN/IEC 62208:2011) and is published in parallel as harmonized regional versions (for example EN IEC 62208:2023). It explicitly excludes enclosures covered by other specific product standards such as certain parts of IEC 60670 where applicable.

FAQ

Q: What is this standard?

A: IEC 62208:2023 is the international standard that sets general requirements and tests for empty enclosures intended for low‑voltage switchgear and controlgear assemblies (3rd edition, 2023).

Q: What does it cover?

A: It covers definitions, classification, construction and testing (mechanical, environmental and basic electrical safety) of empty enclosures supplied by enclosure manufacturers for incorporation into assemblies rated up to 1 000 V AC / 1 500 V DC, including requirements for marking and documentation.

Q: Who typically uses it?

A: Enclosure manufacturers, assembly and switchgear manufacturers, test laboratories, product compliance engineers and regulatory bodies use the standard to design, test and verify empty enclosures for use in low‑voltage assemblies.

Q: Is it current or superseded?

A: IEC 62208:2023 is the current (third) edition and supersedes the 2011 edition. The IEC webstore lists the 2023 publication as the base/current publication. Stability scheduling information indicates the edition's stability period (example: stability date listed to 2026 by the publisher).

Q: Is it part of a series?

A: IEC 62208 is a stand‑alone product standard for empty enclosures but is intended to be used in conjunction with the IEC 61439 series (requirements for low‑voltage switchgear and controlgear assemblies) and other related standards such as IEC 60529 (IP) and IEC 62262 (IK).

Q: What are the key keywords?

A: Empty enclosure, enclosure classification, low‑voltage, switchgear, controlgear, IP code, IK code, type testing, earthing, IEC 62208, IEC 61439.
