IEC 61439-1 and IEC 61439-2 are international standards published by the International Electrotechnical Commission (IEC) that outline the requirements for low-voltage power distribution units (PDUs) and their associated socket outlets. These standards aim to ensure the safety and performance of PDUs and socket outlets used in various applications, including industrial, commercial, and residential settings. IEC 61439 consolidates previous modular standards to provide

Navigating IEC 61439-1 and 61439-2: The Global Standards for Low-Voltage Switchgear

Purpose and scope

• IEC 61439 consolidates previous modular standards to provide a single framework for assessing LV assemblies’ safety, performance and verification.
• Part 1 establishes uniform principles: definitions, documentation, responsibilities of manufacturer, constructional and dielectric properties, temperature rise, short-time withstand, and verification/testing methods.
• Part 2 applies Part 1 to power switchgear and controlgear assemblies (typically distribution boards, switchboards, motor control centers for power distribution), adding requirements and specific verification procedures relevant to power distribution functions.

What is IEC 61439-1?

8. Practical Implications for Manufacturers and Panel Builders

• Original Manufacturer (e.g., Schneider, Siemens, ABB): Performs design verification (tests/calculations) for a standard range.
• Assembly Manufacturer (panel builder): Uses verified design rules or pre-verified sub-assemblies to build custom assemblies without full re-testing, provided all deviations are within allowed limits.
• End user / specifier: Must specify not just components but the complete assembly according to IEC 61439-2, including rated current (Ie), short-circuit rating (Icw or Icc), form of separation, and IP rating.
