IEC 61439-1 Testing

Low-voltage switchgear and controlgear assemblies – Part 1: General rules

IEC 61439-1 Abstract:

IEC 61439 1 and EN 614319 1 testing lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. This standard cannot be used alone to specify an assembly or used for a purpose of determining conformity. Assemblies shall comply with the relevant part of the IEC 61439 series; Parts 2 onwards.

IEC 61439-1 applies to low-voltage switchgear and controlgear assemblies (assemblies) only when required by the relevant assembly standard as follows:

  • Assemblies for which the rated voltage does not exceed 1000 V in case of A.C. or 1500 V in case of D.C.;
  • Stationary or movable assemblies with or without enclosure;
  • Assemblies intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment;
  • Assemblies designed for use under special service conditions, for example in ships and in rail vehicles provided that the other relevant specific requirements are complied with;
  • Assemblies designed for electrical equipment of machines provided that the other relevant specific requirements are complied with.
