EN 61439-3

EN 61439-3 is a European standard that specifies how low-voltage switchgear assemblies—like electrical panels and distribution boards—should be designed, built, and tested to ensure safety, reliability, and proper functioning. It establishes guidelines for construction, performance, and testing procedures, helping manufacturers produce consistent and safe electrical equipment. This standard ensures that these assemblies can safely distribute electricity in commercial, industrial, and residential settings, reducing risks such as electrical faults or failures. Overall, EN 61439-3 promotes standardized quality and safety in electrical device manufacturing and installation across Europe.
