What is difference between IEC 61439 and 60439 ?

IEC 61439 is the latest international standard for low-voltage switchgear and control gear assemblies. It was introduced in 2009 and replaced the previously used standard, IEC 6043The primary objective of IEC 61439 is to ensure the safety and performance of power distribution systems.

The standard covers various aspects such as design verification, temperature rise limits, dielectric properties, and clearances. It emphasizes the importance of testing and verification processes to confirm that assemblies meet the defined requirements. IEC 61439 also provides guidance on documentation, labeling, and technical data that need to be supplied with the equipment.

Differences between IEC 61439 and IEC 60439

One of the significant differences between IEC 61439 and IEC 60439 lies in their approach. While IEC 60439 followed a type-tested concept, IEC 61439 introduces an alternative, more flexible concept called "verification by design." This change allows manufacturers to use validated design software or verified calculation tools to determine the performance and compatibility of their assemblies.

Another notable difference is the level of detail provided in the standards. IEC 61439 offers clearer guidelines and stricter requirements regarding documentation, marking, and test reports. This additional information ensures better traceability and facilitates easier verification of compliance.

The Importance of IEC 61439

IEC 61439 is an essential standard that provides for the design, verification, and documentation of switchgear and control gear assemblies. Its aims to ensure the safety and performance of power distribution systems.

By using IEC 61439, manufacturers can ensure that their switchgear and control gear assemblies meet the required safety standards, are compatible with other equipment, and are suitable for different applications. The standard also provides guidance on the design, verification, and documentation of these assemblies, making it easier for manufacturers to create reliable and safe systems.

Conclusion

In conclusion, IEC 61439 and 60439 are two important standards that govern the design and performance of electrical installations. While both standards have their similarities, IEC 61439 introduces a more flexible approach and provides clearer guidelines for manufacturers.

IEC 61439 is a crucial standard that ensures the safety and performance of power distribution systems. Its implementation is necessary for manufacturers to create reliable and safe switchgear and control gear assemblies. By using IEC 61439, manufacturers can ensure that their products meet the required safety standards and are suitable for different applications.
