What is UL 60947-1:2020?

UL stands for Underwriters Laboratories, which is an independent testing and certification organization that evaluates the safety and performance of various products. UL 60947-1:2020 is a technical standard developed by UL that specifically focuses on low-voltage switchgear and control gear assemblies.

Key Requirements of UL 60947-1:2020

This standard sets out the minimum requirements for design, construction, and performance of low-voltage switchgear and control gear assemblies. It covers aspects such as electrical ratings, mechanical operation, temperature rise, short-circuit withstand strength, functional safety, and environmental conditions.

One of the primary objectives of UL 60947-1:2020 is to ensure the safety of personnel working with or near these electrical devices. It specifies measures to prevent electric shock, thermal effects, energy hazards, and other potential risks associated with faulty equipment or incorrect use.

Furthermore, the standard addresses reliability and protection against damage or malfunction during normal operation, fault conditions, and environmental stress. It requires manufacturers to comply with specific performance tests and provide detailed documentation to support their claims of compliance.

Benefits and Impact

Complying with UL 60947-1:2020 offers several benefits to both manufacturers and end-users. By adhering to the standard's requirements, manufacturers can enhance the quality and reliability of their switchgear and control gear assemblies, leading to improved product performance and increased customer satisfaction.

For end-users, using UL 60947-1:2020 certified products provides a higher level of confidence in terms of safety and dependability. It ensures that the electrical equipment they rely on has undergone rigorous testing and meets strict performance standards, reducing the risk of accidents, equipment failure, and potential damage to other systems or infrastructure.

Additionally, UL 60947-1:2020 compliance can facilitate international trade by harmonizing product standards and creating a level playing field for manufacturers across different regions. It enables easy recognition and acceptance of products in multiple markets, minimizing the need for retesting and certification.


UL 60947-1:2020 is an important standard that sets out the requirements for low-voltage switchgear and control gear assemblies. By complying with this standard, manufacturers can ensure the safety, reliability, and performance of their products, while end-users can have greater confidence in their electrical systems. Overall, UL 60947-1:2020 plays a crucial role in promoting the use of high-quality and safe electrical equipment worldwide.
