The IEC 61439 series establishes international standards for low-voltage switchgear, replacing older 60439 standards with a focus on verified assemblies. Part 1 defines general rules, while Part 2 governs power assemblies, utilizing three methods (testing, calculation, or design rules) to verify performance requirements like temperature rise and short-circuit withstand. For technical details, see the Legrand White Paper www.mchip.net IEC 61439-1 & 2: Low-Voltage Standards | PDF - Scribd Oct 3, 2561 BE —
- Improved safety: The standards provide a framework for designing and testing low-voltage power distribution systems to ensure they meet safety requirements.
- Increased efficiency: The standards provide a common language and set of requirements for manufacturers and users, reducing confusion and errors.
- Enhanced performance: The standards provide a framework for testing and validating the performance of low-voltage power distribution systems.
The Rule: Part 2 cannot be used alone; it refers back to Part 1 for all common requirements. Key Requirements for Compliance iec 614391 and 2 pdf
3. Design Verification (The Big Change from IEC 60439)
Instead of testing every single panel (type testing), manufacturers now perform design verifications via: The IEC 61439 series establishes international standards for
This avoids repeating common content. Any manufacturer claiming compliance to IEC 61439-2 must also meet all relevant clauses of IEC 61439-1. Improved safety: The standards provide a framework for
IEC 61439-2 (Power Switchgear and Controlgear Assemblies): This is the specific product standard for "PSC-assemblies" (often called switchboards or panelboards). It details the construction and performance criteria for power distribution systems. Key Technical Requirements
