Blog post: Where to find the IEC 60439-1 standard PDF and what to know about it
IEC 60439-1 (Low-voltage switchgear and controlgear assemblies — Part 1: Type-tested and partially type-tested assemblies) is a legacy international standard for low-voltage switchgear assemblies. It has been widely used for design and verification of switchgear assemblies but has been largely superseded by IEC 61439 series. If you need the PDF, here’s what to expect and how to proceed.
Issue: Overlooking environmental factors (e.g., humidity in industrial settings). iec 60439-1 standard pdf
TTA (Type-Tested Assemblies): Fully verified through laboratory testing. Blog post: Where to find the IEC 60439-1
Manufacturer Roles: Clarified the difference between the Original Manufacturer (who designs/tests the system) and the Assembly Manufacturer (who builds/modifies it). INTERNATIONAL STANDARD IEC 60439-1 Type testing Routine testing Sampling
The bottom line: You cannot certify a new low-voltage switchboard to IEC 60439-1 today. Notified bodies will reject it.
Verification Approach: The distinction between TTA and PTTA was removed in favor of a more unified verification approach: testing, calculation/measurement, or satisfying strict design rules. Conclusion
The standard covers assemblies that comprise:
- Type testing
- Routine testing
- Sampling
