Power switchgear and controlgear assemblies (PSC-assemblies).
The organization responsible for the completed assembly. This is often the local panel builder who integrates components into an enclosure following the original manufacturer’s instructions. They must perform routine verifications on every completed panel. 3. The Shift from Type Testing to Design Verification
Utilizing the current standard ensures legal compliance in most global markets.
The most significant change from the historic IEC 60439 to the modern IEC 61439 standard was the elimination of the categories (Type-Tested Assemblies) and PTA (Partially Type-Tested Assemblies).
Resistance to corrosion and mechanical impact (IK ratings). iec 614391 and 2 pdf
This method allows a manufacturer to validate a new variant by comparing it structured-form against a reference design that has already been physically tested. Strict mathematical derivation rules apply to ensure the variant does not compromise safety margins. 3. Verification by Assessment
IEC 61439 introduces clear legal and functional distinctions between the entities involved in building a control panel:
Other parts in the series cover specialized applications, such as distribution boards for unskilled persons (Part 3), assemblies for construction sites (Part 4), and assemblies for power distribution in public networks (Part 5). 2. Key Responsibilities Defined by the Standard
According to ABB’s "The standard IEC 61439 in practice" workbook , the standard allows three methods of verification: Physical testing of a sample panel. Power switchgear and controlgear assemblies (PSC-assemblies)
Verification of electrical operations (shunts, trips, relays).
Checking of protective measures and electrical bonding integrity. Why Compliance and PDF Documentation Matter

When looking to purchase or download the , it is vital to source them through legitimate web stores. Electrical safety compliance requires using authentic, up-to-date editions. They must perform routine verifications on every completed
Comparing a new configuration against a similar, structurally tested reference design.
The organization that carries out the original design and performs the initial design verifications (e.g., companies like Schneider Electric, Siemens, or ABB). They provide the blueprints, tested busbar systems, enclosures, and technical documentation.
For full compliance, always refer to the latest editions (both parts updated in 2020). Digital PDF copies are available from the or national standards bodies (e.g., BSI, DIN, ANSI).
