What is IEC 60947-2 Ed.5:2018?

The IEC 60947-2 Ed.5:2018 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear assemblies. It provides guidelines and regulations for the design, construction, testing, and performance of these electrical devices. This international standard ensures the safety and reliability of switchgear and controlgear assemblies, allowing them to be used in various industrial and commercial applications.

Key Features and Changes

The fifth edition of IEC 60947-2 introduces several important features and changes compared to its predecessor. One of the significant updates is the of new temperature-rise limits for busbars. This helps to improve the thermal performance of switchgear and controlgear assemblies, ensuring they can handle higher current loads without overheating.

Another notable change is the revised approach to the coordination of protective devices. The new edition provides more detailed guidance on how to select and coordinate circuit breakers, fuses, and other protective devices to achieve optimal protection against short circuits and overloads.

Benefits of Compliance

Complying with IEC 60947-2 Ed.5:2018 offers various benefits. Firstly, it enhances the safety of switchgear and controlgear assemblies, reducing the risk of electrical accidents and fire hazards. By following the standard's guidelines, manufacturers can ensure their products meet strict quality and performance requirements, instilling confidence in end-users regarding product reliability.

Additionally, adherence to this standard promotes international harmonization, simplifying trade and cooperation between countries. Manufacturers can produce equipment that meets the same standardized requirements, making it easier to export and import their products globally.

Conclusion

The IEC 60947-2 Ed.5:2018 is a crucial technical standard for low-voltage switchgear and controlgear assemblies. It sets out guidelines and requirements to ensure the safety, reliability, and performance of these electrical devices. Compliance with this international standard brings benefits such as improved safety, enhanced product quality, and easier global trade.
