The standard allows the Original Manufacturer to use three distinct methods to verify these characteristics: iec 614391 and 2 pdf

Uncontrolled heat degrades insulation and leads to premature equipment failure. IEC 61439-2 requires clear limits for temperature rise across different parts of the panel (e.g., busbars, terminals, accessible enclosures).

This is the organization that carries out the initial design and completes the extensive (the 12 attributes listed above). This is typically a major engineering firm or automation supplier (e.g., Schneider Electric, ABB, Siemens) that creates a specific system product line. The Assembly Manufacturer

Organizations like BSI (BS EN 61439 in the UK), DIN (Germany), or Bureau of Indian Standards (BIS) sell localized versions containing identical technical texts. | Aspect | Details | | :--- |

Many universities, large engineering firms, and testing laboratories subscribe to standards databases like IECL (IEC Standards Collection) or Perinorm . If you work for such an organization, you can access the PDF for free via their internal network.

Understanding IEC 61439-1 and -2: The Global Standard for Low-Voltage Switchgear (PDF Guide)

The IEC 61439 series replaced the older IEC 60439 standard to eliminate ambiguities and modernize verification methods. The series is split into a general rules document and several product-specific parts. IEC 61439-2 requires clear limits for temperature rise
