What is BS EN 61439-2011?

BS EN 61439-2011 is a technical standard that lays down specific requirements for the design, construction, and testing of low-voltage switchgear and control gear assemblies. It provides guidelines for manufacturers, installers, and users to ensure the safe and reliable operation of such assemblies. This standard replaces the older IEC60439-1 standard and is widely recognized and implemented globally.

The Scope of BS EN 61439-2011

The standard covers various types of low-voltage switchgear and control gear assemblies, including distribution boards, motor control centers, and power supply systems. It defines the performance criteria, mechanical strength, degree of protection, and electrical features that these assemblies must meet. It specifies clear requirements for the temperature rise, short-circuit withstand capability, and resistance to internal and external faults. By following the guidelines set by the standard, manufacturers can ensure their products' compliance and reliability.

Importance of Complying with BS EN 61439-2011

Compliance with BS EN 61439-2011 is crucial for both manufacturers and end-users. For manufacturers, it serves as a benchmark for designing and producing high-quality switchgear and control gear assemblies. By complying with this standard, they can ensure the safety and performance of their products and gain a competitive edge in the market. On the other hand, end-users benefit from using compliant products as they are assured of their reliability, long service life, and reduced risk of electrical accidents or failures.

The Testing and Certification Process

To ensure compliance with BS EN 61439-2011, manufacturers need to subject their switchgear and control gear assemblies to rigorous testing and certification processes. These processes include type testing, routine verification, and assessment of their design and production processes. Type testing involves intensive testing of a sample assembly to verify its performance under various conditions. Routine verification is conducted on each individual assembly to ensure consistent quality. The assessment of design and production processes ensures that manufacturers have established proper quality control measures.

In conclusion, BS EN 61439-2011 is a vital technical standard that sets forth essential requirements for low-voltage switchgear and control gear assemblies. Compliance with this standard ensures the safety, reliability, and performance of such assemblies, benefiting both manufacturers and end-users. By adhering to the guidelines specified in the standard, manufacturers can produce high-quality products while end-users can rely on their safe operation. The testing and certification processes further guarantee the compliance of these assemblies with the standard.
