IEC 61439-1 is an international standard that specifies the general requirements for low-voltage switchgear and controlgear assemblies. It covers assemblies with rated voltages not exceeding 1000 V AC or 1500 V DC. It applies to both factory-built assemblies (FBA) and partially type-tested assemblies (PTTA).
The standard defines the terms and definitions, service conditions, construction requirements, technical characteristics, verification methods, documentation, and marking of low-voltage switchgear and controlgear assemblies. It also provides guidance on how to use other parts of the IEC 61439 series that deal with specific types of assemblies.
Using IEC 61439-1 can help you ensure that your low-voltage switchgear and controlgear assemblies are safe, reliable, and compliant with the relevant regulations. It can also help you improve your product quality, performance, and efficiency. By following the standard, you can demonstrate your competence and credibility to your customers, suppliers, and regulators.
But how can you get access to this valuable standard? You may be tempted to look for a free download online, but this is not a good idea. In this article, we will explain why you should avoid downloading IEC 61439-1 PDF for free and how you can obtain a legitimate copy of the standard.
What are the main changes in IEC 61439-1:2020?
IEC 61439-1 is not a static document. It is regularly revised and updated to reflect the latest developments in technology, market needs, and industry best practices. The most recent edition of the standard was published in July 2020 and replaced the previous edition from 2011.
So what are the main changes in IEC 61439-1:2020? Here are some of the key differences between the new and old versions of the standard:
The scope of the standard has been clarified and expanded to include assemblies intended for use in explosive atmospheres, photovoltaic applications, electric vehicles, marine environments, etc.
The definitions of some terms have been modified or added, such as "assembly", "functional unit", "distribution board", "forms of internal separation", etc.
The service conditions have been revised to include more parameters, such as altitude, humidity, pollution degree, mechanical loads, etc.
The construction requirements have been updated to address new aspects, such as electromagnetic compatibility (EMC), fire resistance, arc fault containment, etc.
The technical characteristics have been restructured and supplemented to cover more features, such as rated diversity factor, rated conditional short-circuit current, rated frequency, etc.
The verification methods have been refined and harmonized to provide more consistency and clarity. The standard now specifies the minimum number of samples, the sequence of tests, the acceptance criteria, etc.
The documentation and marking requirements have been enhanced to provide more information and transparency. The standard now requires the provision of a declaration of conformity, a risk assessment, a user manual, etc.
These changes have significant implications for manufacturers, designers, and users of low-voltage switchgear and controlgear assemblies. They need to familiarize themselves with the new requirements and ensure that their products and processes are compliant with the latest edition of the standard.
How to design and test low-voltage switchgear and controlgear assemblies according to IEC 61439-1:2020?
Designing and testing low-voltage switchgear and controlgear assemblies according to IEC 61439-1:2020 is not a simple task. It requires a thorough understanding of the standard and its application to different types of assemblies. It also requires a rigorous verification process that can prove the conformity of the assemblies with the standard.
The standard defines four types of assemblies based on their design and verification methods:
Type-tested assemblies (TTA): assemblies that have been verified by testing a representative sample of the complete assembly or one or more functional units.
Partially type-tested assemblies (PTTA): assemblies that have been verified by testing a representative sample of some parts or components of the assembly or functional unit.
Design verification by testing (DVBT): assemblies that have been verified by testing a design that is not covered by TTA or PTTA.
Design verification by assessment (DVBA): assemblies that have been verified by assessment based on engineering principles, calculations, simulations, etc.
The standard specifies different design rules and requirements for each type of assembly. For example, TTA and PTTA require the use of standardized components that have been tested according to IEC 61439-2 or other relevant standards. DVBT and DVBA require the use of design rules that have been validated by testing or assessment.
The standard also specifies different verification methods and procedures for various aspects of performance, such as temperature rise, short-circuit withstand strength, dielectric properties, protection against electric shock, mechanical operation, etc. For each aspect, the standard defines the test conditions, the test equipment, the test procedure, and the acceptance criteria.
The standard provides examples of test reports and certificates that can be used to document the verification results. These documents should include information such as the identification of the assembly, the type of verification, the test method, the test results, the deviations or non-conformities, etc.
