What is BS EN 61439-2:2018?

Introduction

BS EN 61439-2:2018 is a technical standard that specifically focuses on low-voltage switchgear and control gear assemblies. It lays down the general rules relating to the construction, testing, and safe use of these assemblies. The standard helps ensure that switchgear and control gear assemblies are designed and built in a way that guarantees their safety and reliability.

Key Elements of BS EN 61439-2:2018

One of the key elements of the BS EN 61439-2:2018 standard is the definition of its scope. The standard applies to low-voltage switchgear and control gear assemblies with rated voltages not exceeding 1000V AC or 1500V DC. It covers both indoor and outdoor installations, and includes a wide range of assembly types such as distribution boards, motor control centers, and panelboards.

The standard also provides guidelines for the design of switchgear and control gear assemblies. It specifies requirements for various aspects, including the mechanical structure, electrical function, temperature rise limits, and degree of protection. These guidelines aim to ensure that the assemblies are robust, functional, and appropriately protected from external factors.

In addition, BS EN 61439-2:2018 outlines the testing methods and type tests that should be performed on switchgear and control gear assemblies. These tests evaluate the performance and suitability of the assemblies in different conditions, such as normal operation, short-circuit scenarios, and abnormal duty situations. The standard defines the test procedures and acceptance criteria, providing a basis for assessing the conformity of the assemblies to the standard.

Benefits of Compliance

Compliance with BS EN 61439-2:2018 offers several benefits for manufacturers, suppliers, and end-users. Firstly, adherence to the standard ensures that the switchgear and control gear assemblies meet the necessary safety requirements, minimizing the risk of electrical accidents or hazards.

Secondly, compliance guarantees a certain level of performance and reliability for these assemblies. By following the guidelines provided in the standard, manufacturers can design and produce products that meet the expected quality standards. This provides assurance to customers that the switchgear and control gear assemblies will perform effectively and consistently over their intended lifespan.

In addition, conforming to BS EN 61439-2:2018 supports compatibility and interoperability between different assemblies and components. The standard directs manufacturers to ensure that their products are compatible with others, enabling easy integration and replacement of parts when needed.

Conclusion

BS EN 61439-2:2018 is an important technical standard that plays a crucial role in ensuring the safety and reliability of low-voltage switchgear and control gear assemblies. By providing guidelines for construction, testing, and use, the standard establishes a framework for manufacturers to produce high-quality products that comply with safety regulations and industry requirements. Compliance with this standard not only enhances the safety and performance of switchgear and control gear assemblies but also promotes compatibility and interoperability among different components and systems.
