What is UL 60947-19-2020 ?

Title: What is UL 60947-19-2020 and Why is it Important?

UL 60947-9-2020 and UL 60947-8-2020 are two important international standards that set the guidelines for low-voltage switchgear and controlgear products. As a critical part of the electrical industry, it is essential to understand the purpose and key features of these standards to ensure the safety and reliability of these electrical devices.

Purpose of UL 60947-9-2020:

UL 60947-9-2020 is a professional technical standard published by Underwriters Laboratories (UL) that provides a standardized framework for manufacturers, regulators, and end-users to evaluate and compare low-voltage switchgear and controlgear products. The primary objective of UL 60947-9-2020 is to ensure that these products meet industry safety standards and perform consistently in various operating conditions.

Purpose 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, ensuring their safety and performance. This standard is designed to establish guidelines for manufacturers, installers, and users of low-voltage switchgear and controlgear products, ensuring that they meet specific safety standards and minimize the risks to people and property.

Key Features and Requirements of UL 60947-9-2020:

UL 60947-9-2020 provides a comprehensive set of requirements for the design, manufacture, and testing of low-voltage switchgear and controlgear products. The standard outlines the key features and requirements of the product, including:

Electrical Safety: The standard specifies the maximum allowable voltage levels, current ratings, and other electrical safety-related requirements.

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

Environmental Resistance: The standard requires that the switchgear be capable of operating in harsh environmental conditions, such as high temperature, low temperature, and high humidity.

Electrical Interference: The standard specifies the limits on electrical interference from other sources, such as radio frequency interference.

Radio Frequency Reach: The standard outlines the limits on radio frequency (RF) reach, which is the distance from the switchgear where the user can still receive a signal.

Durability: The standard specifies the level of durability required for the switchgear, including the expected service life and the ability to withstand various types of environmental stress, such as impact, vibration, and aging.

Conclusion:

UL 60947-9-2020 and UL 60947-8-2020 are essential international standards that provide the framework for manufacturers, installers, and users of low-voltage switchgear and controlgear products. Compliance with these standards is critical to ensure the safety and reliability of these electrical devices. By understanding the key features and requirements of these standards, technical professionals can ensure that the products they install or use meet the necessary safety standards and perform consistently in various operating conditions.
