What is IEC 60947-4-2 Ed.3:2018?

The world of electrical engineering is constantly evolving, with new standards and regulations being introduced to ensure safety and reliability. One such standard is IEC 60947-4-2 Ed.3:2018. But what exactly is IEC 60947-4-2 Ed.3:2018 and how does it impact the industry?

Understanding the Scope

IEC 60947-4-2 Ed.3:2018 is a technical standard published by the International Electrotechnical Commission (IEC). It specifically focuses on low-voltage switchgear and controlgear assemblies. The standard outlines the performance requirements, tests, and ratings for these electrical devices.

This standard is applicable to applications with rated voltages up to 1000V AC or 1500V DC, and rated currents up to 6300A. It covers both AC and DC switchgear and controlgear assemblies used in industrial, commercial, and residential settings.

Key Changes and Updates

The third edition of IEC 60947-4-2 brings several important changes and updates compared to its previous versions. These changes are aimed at improving safety, performance, and interoperability of switchgear and controlgear assemblies.

One significant update is the inclusion of specific requirements for electronic circuits used in these assemblies. This ensures that the control circuits are reliable and capable of functioning correctly under various conditions.

Additionally, the latest edition introduces new terms and definitions that align with international standards, promoting consistency and clarity in communication within the industry.

Benefits and Implications

Adhering to IEC 60947-4-2 Ed.3:2018 offers several benefits for manufacturers, suppliers, and users of switchgear and controlgear assemblies.

Firstly, compliance with the standard ensures that the electrical devices meet the necessary safety requirements, minimizing the risk of electrical shocks, fires, or other hazards. This is especially crucial in high-risk environments such as industrial facilities.

Furthermore, using IEC 60947-4-2-compliant equipment enhances interoperability between different components and systems. This simplifies integration and maintenance processes and reduces potential compatibility issues.

In conclusion, IEC 60947-4-2 Ed.3:2018 plays a vital role in ensuring the safety and reliability of low-voltage switchgear and controlgear assemblies. Its implementation guarantees that electrical devices meet rigorous performance standards, promoting overall industry quality and fostering a safer working environment.
