Overview

EN 60669-2-4:2005 - Switches for household and similar fixed electrical installations, Part 2-4: Particular requirements - Isolating switches (CLC/CENELEC adoption of IEC 60669-2-4:2004, modified). This European standard applies to manually operated general-purpose isolating switches with a rated voltage up to 440 V and rated current up to 125 A, intended for household and similar fixed electrical installations, both indoor and outdoor. It is intended to be used together with EN 60669-1:1999 and includes CENELEC common modifications and national provisions (Annex ZA and ZB).

Key topics and technical requirements

This standard defines particular requirements for isolating switches and covers technical areas such as:

• Ratings - rated voltage and current limits (≤ 440 V, ≤ 125 A) and national rating conditions (see Annex ZB).
• Terminals - design and suitability of terminals for conductors and connections.
• Constructional requirements - mechanical design, enclosures and user operability for safe isolation.
• Temperature rise - permissible heating under rated conditions to ensure safe continuous operation.
• Making and breaking capacity - requirements for the switch’s ability to make and interrupt currents safely.
• Normal operation - functional performance, durability and switching behaviour for manual isolators.
• National special conditions - Annex ZB documents country-specific exemptions or adaptations (for example, UK provisions allowing isolators with ratings below 16 A).
• Normative references and harmonization - references to related IEC/EN documents (e.g., IEC 61180-1) and harmonized clauses.

Applications

EN 60669-2-4:2005 is practical for:

• Specifying and testing isolating switches used in residential, commercial and similar fixed installations.
• Ensuring product safety, interchangeability and regulatory compliance across CENELEC countries.
• Supporting selection of isolators for indoor or outdoor distribution, switchboards, local isolation points and maintenance safety.
• Guiding manufacturers during design, type testing and documentation for CE marking and national approvals.

Who uses this standard

• Switch and electrical accessory manufacturers (product design and certification)
• Test laboratories and conformity assessment bodies (type testing and verification)
• Electrical installers, contractors and specifiers (product selection and safe installation)
• Regulators and procurement teams (compliance criteria and tender specifications)
• Safety engineers and maintenance personnel (operational and maintenance guidance)

Related standards

• EN 60669-1:1999 (general requirements for switches)
• IEC 60669-2-4:2004 (international base standard)
• Referenced documents such as IEC/EN publications listed in Annex ZA.
