UL 60947-4-2

In the world of electronics and electrical equipment, there are various standards and certifications that ensure safety and performance. One important standard to familiarize yourself with is UL 60947-4-2. In this article, we will explore what UL 60947-4-2 entails and why it is crucial for manufacturers and consumers alike.

The Basics of UL 60947-4-2

UL 60947-4-2 is a global standard established by Underwriters Laboratories (UL), an independent safety science organization. It specifically focuses on low voltage switchgear and control gear assemblies. This standard covers a wide range of products including circuit breakers, contactors, switches, and more.

To obtain UL 60947-4-2 certification, manufacturers must undergo rigorous testing to ensure that their products comply with the safety requirements outlined in the standard. These tests evaluate factors such as electrical insulation, resistance to short circuits, temperature rise, and mechanical operation. Once a product successfully meets all the criteria, it is awarded the UL certification mark.

Importance of UL 60947-4-2

UL 60947-4-2 certification is vital for several reasons. Firstly, it guarantees that the electrical equipment you purchase meets stringent safety standards. This ensures the protection of lives and property by reducing the risk of electrical hazards, such as fires or electric shocks.

Secondly, compliance with UL 60947-4-2 helps promote interoperability among different manufacturers' equipment. This means that devices from multiple brands can work together seamlessly, improving efficiency and compatibility in various electrical systems.

Furthermore, UL 60947-4-2 certification enhances the reputation and credibility of manufacturers. Displaying the UL certification mark signifies that a product has undergone extensive testing and meets the highest safety and performance standards in the industry. This builds trust among consumers, who can confidently choose products that bear the UL mark.


In conclusion, UL 60947-4-2 is a crucial standard for low voltage switchgear and control gear assemblies. It ensures that electrical equipment meets strict safety requirements, promotes interoperability, and enhances the reputation of manufacturers. As a consumer, it is important to look for the UL certification mark when purchasing electrical products, as it signifies reliability and adherence to high standards. By following UL 60947-4-2, we can create a safer and more efficient electrical environment.
