Title: What is UL 60947-8-2020 and Why is it Important?

The Underwriters Laboratories (UL) is a global safety certification company that publishes numerous technical standards, including UL 60947-9-2020. This article will focus on the purpose and key features of UL 60947-8-2020, which is an international standard for low-voltage switchgear and control gear products.

What is UL 60947-8-2020?

UL 60947-8-2020 is an international standard that establishes guidelines for manufacturers, installers, and users of low-voltage switchgear and control gear products. This standard focuses on devices used in circuits of up to 1, 000 V AC and 1, 500 V DC, ensuring their safety and performance.

The primary objective of UL 60947-8-2020 is to establish guidelines for manufacturers, installers, and users of low-voltage switchgear and control gear products, ensuring their safety and performance. Compliance with this standard guarantees that the products are designed and manufactured to withstand electrical, mechanical, thermal, and other stresses.

Key Features and Requirements:

UL 60947-8-2020 has several key features and requirements that manufacturers and users must meet to ensure the safety and performance of the electrical devices. These features and requirements include:

Electrical Safety: The standard outlines the maximum allowable voltage levels, current densities, and other electrical characteristics to ensure the safety of the electrical equipment.

Performance: The standard specifies the tests that must be performed to verify that the switchgear and controlgear products meet the specified requirements for performance, such as short-circuits, over-currents, and voltage drops.

Reliability: The standard outlines the testing procedures for determining the reliability of the switchgear and controlgear products, including tests for durability, short-circuits, and over-currents.

Environmental Strain: The standard specifies the tests that must be performed to determine the environmental resistance of the switchgear and controlgear products, including tests for high temperature, low temperature, and exposure to various environmental factors.

Electrical Interference: The standard outlines the tests that must be performed to determine the electrical interference that can occur from other electrical equipment, including tests for immunity to interference from different frequency sources.

Conclusion:

UL 60947-8-2020 is an important international standard for low-voltage switchgear and control gear products. It ensures that these products meet specific safety standards, minimizing risks to both people and property. Compliance with this standard guarantees that the products are designed and manufactured to withstand electrical, mechanical, thermal, and other stresses. As the safety of the people and the properties are of utmost importance, this standard is widely recognized and followed by manufacturers, installers, and users of low-voltage switchgear and control gear products.
