About standard IEC-61439

What does it mean?

The IEC 61-439 standard aims to standardize all the rules and requirements applicable to the low-voltage switchgear and controlgear assemblies.
Main objective is to make requirements and checks uniform, avoiding thus any verification according to other standards.

The IEC 61439 standard specifies responsibilities of each party, by differentiation those of the original manufacturer from those of the assembly manufacturer.

1 - Sets out responsibilities and obligations of each party

  • The original manufacturer is responsible for design verification using a series of tests, calculations and rules.
  • The assembly manufacturer is responsible for selecting components and mounting and wiring the switchboard according to the mounting rules of the original manufacturer.

2 - Clarifies specification requirements

  • The assembly manufacturer must provide documents specifying the conditions required for installing, operating and maintaining the assembly and its devices.

3 – Routine verifications by the panel builder: 9 check points

  • The assembly manufacturer must perform 9 routine verification for each assembly: 7 concern the construction of the assembly, while the other 2 relate to its performance.

4 – Assembly made identifiable by marking it with permanent labels

  • Each assembly should contain a label that specifies the name of the original manufacturer, the type designation or an identification number, the manufacturing date and the standard used.Inside the assembly.

5 - Documentary traceability, test certificates and CE certification

  • The assembly manufacturer must provide documents specifying the conditions required for installing, operating and maintaining the assembly and its devices.
