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

UL 60947-8-2020 is a professional technical standard published by Underwriters Laboratories (UL) that sets the guidelines for low-voltage switchgear and controlgear products. It is designed to ensure the safety, reliability, and performance of these electrical devices. In this article, we will discuss the purpose of UL 60947-8-2020 and its key features and requirements.

Purpose of UL 60947-8-2020:

UL 60947-8-2020 is primarily designed to establish guidelines for manufacturers, installers, and users of low-voltage switchgear and control gear products. The standard aims to minimize the risks to both people and property associated with these products. It provides a standardized framework for evaluating and comparing these products, ensuring that they meet industry safety standards and perform consistently in various operating conditions.

Key Features and Requirements of UL 60947-8-2020:

UL 60947-8-2020 is an international standard that focuses on devices used in circuits of up to 1, 000 V AC and 1, 500 V DC. It is important to note that this standard does not apply to products used in higher voltage circuits.

The primary objective of UL 60947-8-2020 is to ensure the safety, reliability, and performance of low-voltage switchgear and controlgear products. It provides guidelines for manufacturers, installers, and users to evaluate and compare these products, ensuring they meet specific safety standards.

To achieve this objective, UL 60947-8-2020 outlines several key features and requirements for the products. These requirements include:

Electrical Safety: The standard specifies the maximum allowable voltage levels, current ratings, and overvoltage/overcurrent protection for the various electrical components of the switchgear.

Performance: The standard outlines the performance requirements for the switchgear, including the maximum switching frequency, voltage drops, and response time.

Robustness: The standard specifies the environmental conditions that the switchgear can withstand, such as temperature, humidity, and vibration.

Electrical Interference: The standard prohibits the use of certain materials and components that may interfere with the electrical performance of the switchgear.

Radio Frequency (RF) and Microwave Interference: The standard also prohibits the use of certain materials and components that may interfere with the RF or microwave performance of the switchgear.

Vibration and Shock: The standard specifies the acceptable levels of vibration and shock that the switchgear can withstand.

Electrical Noise: The standard outlines the acceptable levels of electrical noise for the switchgear.

Conclusion:

UL 60947-8-2020 is an important international standard that provides guidelines for manufacturers, installers, and users of low-voltage switchgear and controlgear products. It is designed to ensure the safety, reliability, and performance of these electrical devices, while also minimizing the risks to both people and property. By ensuring that the switchgear meets industry safety standards, manufacturers can guarantee that their products are designed and manufactured to withstand electrical, mechanical, thermal, and other stresses.
