What is IEC 61439-6 Ed.2:2018?

The IEC 61439 standard is a technical specification that provides guidelines and requirements for Low-Voltage switchgear and controlgear assemblies. Specifically, IEC 61439-6 Ed.2:2018 focuses on the testing and verification of power switchgear and control gear assemblies.

Key Changes in IEC 61439-6 Ed.2:2018

IEC 61439-6 Ed.2:2018 introduces several significant changes compared to its previous edition. One of the notable changes is the new set of tests, which includes additional environmental tests to ensure the reliability and safety of assemblies in various operating conditions.

Another important change is the revised verification procedure for temperature rise limits. The new edition specifies more detailed calculations and criteria for assessing temperature rise, providing more accurate results and ensuring the durability of assemblies.

Impact and Benefits of IEC 61439-6 Ed.2:2018

The updated standard brings several benefits to both manufacturers and end-users. Firstly, it enhances the quality and performance of power switchgear and control gear assemblies by setting stricter testing and verification requirements.

Moreover, the new environmental tests included in the standard result in assemblies that demonstrate better resistance to harsh conditions, such as extreme temperatures, humidity, and vibration. This improvement ensures the longevity and reliability of the assemblies in diverse environments.

Furthermore, the revised verification procedure for temperature rise limits enables manufacturers to design and produce assemblies more precisely, considering the thermal effects and limitations. Consequently, this leads to more efficient and safer operation of switchgear assemblies.

Conclusion

IEC 61439-6 Ed.2:2018 significantly contributes to the advancement and standardization of power switchgear and control gear assemblies. Its updated testing and verification requirements, including additional environmental tests and revised temperature rise limits, ensure higher quality, reliability, and safety in electrical installations.

The adoption of this standard benefits both manufacturers and end-users by enhancing the performance and durability of such assemblies. It also promotes consistency and interoperability in the industry, facilitating the integration and exchange of different assemblies from various suppliers.
