This is the "umbrella" standard. It contains all the general definitions, service conditions, construction requirements, performance characteristics, and verification methods that apply to any type of low-voltage assembly (up to 1,000 V AC or 1,500 V DC).

When users search for , they are almost always seeking the core duo: the General Rules (Part 1) and the Power-specific rules (Part 2).

Assessing the adequacy of terminal connections for field wiring. Performance Characteristics iec 614391 and 2 pdf

To ensure that the assemblies they build are "Design Verified." You cannot claim compliance without following the specific testing and calculation protocols outlined in these documents.

Because Part 2 references back to Part 1, users hate flipping between two massive documents. A combined (if unofficially combined) is a valued resource. This is the "umbrella" standard

Using an unauthorized PDF for commercial panel design or certification (e.g., CE, UKCA, or CCC marking) is risky. Auditors and certification bodies (like TÜV, UL, or DEKRA) require proof that you referenced the (which as of 2024 is Edition 2 or 3 for most parts). An outdated or bootlegged PDF may lead to non-compliance and liability.

The is the internationally recognized benchmark for the design, verification, and performance of Low-Voltage Switchgear and Controlgear Assemblies (ASSEMBLIES)—commonly known as switchboards, distribution boards, and motor control centers (MCCs). These standards replaced the earlier IEC 60439 series in 2009, introducing a fundamental shift from type-tested to design-verified assemblies. Assessing the adequacy of terminal connections for field

The design is verified through the strict application of calculations and design rules, including safety margins. For example, temperature rise can be verified via assessment using simple calculation models if the total current is low (typically under 630 A). 4. Crucial Technical Requirements in Parts 1 and 2

The assembly manufacturer issues a test report and attaches a nameplate featuring the manufacturer's name, serial number, rated currents, and the specific IEC standards applied. Summary of Critical Responsibilities Responsibility of Original Manufacturer Responsibility of Assembly Manufacturer Short-Circuit Proofing Validates busbar system limits via lab tests. Selects components matching the validated limits. Thermal Performance Provides heat dissipation data for enclosures. Performs thermal calculation based on actual layout. Final Inspection Supplies instruction manuals and guidelines. Conducts final routine testing on the specific build.

Formulates the definitions, operating conditions, construction requirements, technical characteristics, and verification requirements common to all low-voltage assembly types.

While IEC 61439-1 provides general rules for low-voltage switchgear and controlgear assemblies, IEC 61439-2 provides specific requirements for power distribution units (PDUs). The key differences between the two standards are:
