What is BS EN 61439-6:2018?

BS EN 61439-6:2018 is a technical standard that defines the specific requirements for low-voltage switchgear and controlgear assemblies. It provides guidelines for the design, manufacturing, and testing of these assemblies to ensure their safe and reliable operation.

Understanding the Scope

The scope of BS EN 61439-6:2018 encompasses various aspects related to low-voltage switchgear and controlgear assemblies. It covers their electrical and mechanical requirements, as well as the methods for verifying compliance with the standard. Furthermore, it addresses the coordination between different components within the assembly and provides guidelines for their integration.

Key Requirements

BS EN 61439-6:2018 outlines several key requirements that need to be followed when designing and manufacturing low-voltage switchgear and controlgear assemblies. These include considerations for temperature rise, short-circuit withstand strength, and protection against electric shock. The standard also specifies requirements for internal electrical circuits, insulation properties, and clearances and creepage distances to minimize the risk of arcing or accidental contact.

Compliance and Testing

To ensure compliance with BS EN 61439-6:2018, manufacturers need to perform various tests on their assemblies. These tests evaluate parameters such as dielectric properties, mechanical durability, and resistance to heat and fire. Compliance with the standard indicates that the assemblies meet certain quality and safety criteria, providing confidence in their performance and reliability. Regular auditing and inspection can help maintain compliance even after the initial certification.

In conclusion, BS EN 61439-6:2018 is a technical standard that sets forth requirements for low-voltage switchgear and controlgear assemblies. By following this standard, manufacturers can design and produce assemblies that are safe, reliable, and compliant with industry guidelines. This ensures the protection of electrical systems and helps prevent potential hazards or accidents.
