Introduced design verification by test/calculation. | | Edition 1.1 | 2011 | Consolidated with Amendment 1 (2010). Clarified temperature rise testing. | | Edition 2.0 | 2020 | Major revision. Added requirements for assemblies with electronic circuits, new clearances for DC, updated short-circuit testing. | | Edition 2.1 | 2021 | Consolidated with Amendment 1 (2021). Minor corrections to Annex E. |

Recommendation: Always purchase Edition 2.1 (2021) or later. Older editions are not recognized for new CE marking or most international tenders.

If you operate globally, you may need to compare IEC 61439-1 with regional standards. The IEC 61439-1 standard has evolved

| Standard | Region | Key Difference from IEC 61439-1 | |----------|--------|--------------------------------| | UL 508A | North America | Uses SCCR (Short-Circuit Current Rating) instead of Icc. Different temperature rise test (e.g., 50°C ambient allowed). | | CSA C22.2 No. 29 | Canada | Similar to UL but with additional Canadian deviations. | | AS/NZS 61439.1 | Australia/New Zealand | Identical to IEC but with annexes for tropical conditions and specific grid voltages (e.g., 415V). | | GB/T 7251.1 | China | Modified adoption of IEC 61439-1. Includes unique requirements for altitude and pollution in Chinese industrial zones. |

If your PDF is the pure IEC version, it may not satisfy local deviations. Always check national forewords.
