UL 60947-6-3:2020 is a professional technical standard that provides guidelines for low-voltage switchgear and controlgear assemblies. It was published by Underwriters Laboratories (UL), a renowned global safety certification organization. This standard specifically focuses on the requirements of arc-fault containment devices (AFCDs) within low-voltage switchgear and controlgear assemblies.
The Importance of UL 60947-6-3:2020
UL 60947-6-3:2020 plays a vital role in ensuring the safety and reliability of electrical installations. The emergence of arc faults can result in severe consequences, including fire hazards and equipment damage. Therefore, it is crucial to have proper guidelines in place to prevent and contain such incidents. This standard provides manufacturers, installers, and end-users with a comprehensive set of requirements and test methods for AFCDs, enabling them to design, build, and use safe switchgear and controlgear assemblies.
Key Requirements of UL 60947-6-3:2020
UL 60947-6-3:2020 establishes various criteria that AFCDs must meet to ensure effective containment and mitigation of arc faults. These criteria include performance testing, marking requirements, temperature rise limits, mechanical strength, and durability assessments. With these requirements, the standard aims to offer a high level of protection against the risks associated with arcing faults, while also promoting consistency and quality in the manufacturing and use of switchgear and controlgear assemblies.
