What is BS EN 61439-1:2011?

BS EN 61439-1:2011 is a technical standard that specifically addresses the safety and performance requirements for low-voltage switchgear and controlgear assemblies. It sets out the criteria for design verification and testing of these assemblies, ensuring they comply with the necessary quality and safety standards. This standard provides guidelines for both manufacturers and customers to ensure the proper functioning and safety of electrical systems.

Key Features of BS EN 61439-1:2011

BS EN 61439-1:2011 comprises several key features that outline the requirements for low-voltage switchgear and controlgear assemblies:

Assembly design: The standard defines requirements for the design, including clearances, creepage distances, temperature rise limits, insulation properties, accessibility, and other factors important for safe and efficient operation.

Busbar and connection systems: It specifies the guidelines for busbar and connection systems, ensuring they are able to carry the required currents safely and effectively without causing excessive heating or loss of performance.

Temperature rise limitations: The standard sets maximum temperature limits for different components of the assembly, preventing potentially hazardous conditions that could lead to malfunction or damage.
