IEC 61439-1 PDF Free Download - What You Need to Know
If you are looking for a free download of the IEC 61439-1 standard, you might be interested in knowing more about this document and its relevance for low-voltage switchgear and controlgear assemblies. In this article, we will provide you with some basic information about the IEC 61439-1 standard, its scope, its main features, and its benefits.
What is the IEC 61439-1 standard?
The IEC 61439-1 standard is an international standard that specifies the general rules for low-voltage switchgear and controlgear assemblies (LVSCAs). LVSCAs are combinations of electrical equipment that are used to distribute, control, and protect electrical circuits and equipment in low-voltage systems. LVSCAs can be found in various applications, such as industrial plants, buildings, data centers, renewable energy systems, and electric vehicles.

The IEC 61439-1 standard defines the terms and definitions, the design and construction requirements, the verification methods, and the marking and documentation requirements for LVSCAs. The standard also provides guidance on how to select the appropriate type of LVSCA for a specific application and how to ensure its safety and performance.
What is the scope of the IEC 61439-1 standard?
The IEC 61439-1 standard applies to LVSCAs for which the rated voltage is under 1000 V AC (at frequencies not exceeding 1000 Hz) or 1500 V DC. The standard covers both factory-built assemblies (FBAs) and assemblies for specific applications (ASAs), as well as partially type-tested assemblies (PTTAs) and fully type-tested assemblies (TTAs). The standard does not apply to individual devices or components that are part of an LVSCA, such as circuit breakers, fuses, relays, etc.
What are the main features of the IEC 61439-1 standard?
The IEC 61439-1 standard introduces some new features that aim to improve the quality and reliability of LVSCAs. Some of these features are:
The concept of design verification: The standard requires that every LVSCA undergoes a design verification process that proves its compliance with the relevant requirements. The design verification can be done by testing, calculation, or comparison with a reference design. The design verification covers aspects such as temperature rise, short-circuit withstand, protection against electric shock, mechanical operation, etc.
The concept of assembly verification: The standard requires that every LVSCA undergoes an assembly verification process that confirms its conformity with the design documentation and the manufacturer's instructions. The assembly verification can be done by inspection or routine testing. The assembly verification covers aspects such as wiring, earthing, clearances, creepage distances, etc.
The concept of design verified assemblies (DVAs): The standard introduces a new category of LVSCAs that are based on a design verification by testing or calculation. DVAs offer more flexibility and customization than TTAs or PTTAs, as they allow for variations in components, materials, arrangements, etc., as long as they do not affect the verified characteristics of the assembly.
What are the benefits of the IEC 61439-1 standard?
The IEC 61439-1 standard provides several benefits for both manufacturers and users of LVSCAs. Some of these benefits are:
Increased safety and performance: The standard ensures that every LVSCA meets the minimum requirements for safety and performance, regardless of its type or application. The standard also reduces the risk of failures or malfunctions due to improper design or assembly.
Enhanced compatibility and interoperability: The standard harmonizes the technical specifications and verification methods for LVSCAs across different regions and markets. The standard also facilitates the integration of LVSCAs with other electrical equipment and systems.
Simplified selection and installation: The standard provides clear guidance on how to select the appropriate type of LVSCA for a specific application and how to install it correctly. The standard also simplifies the documentation and marking requirements for LVSCAs.
Reduced costs and time: The standard allows for more efficient and cost-effective production and delivery of LVSCAs, as it eliminates the need for multiple tests or certifications for different markets or applications. The standard also enables faster and easier adaptation of LVSCAs to changing customer needs or requirements.
