What is UL 60947-67-2020 ?

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

The Underwriters Laboratories (UL) is a global safety certification company that publishes the UL 60947-9-2020 and UL 60947-8-2020 standards. These standards are designed to ensure the safety, reliability, and performance of low-voltage switchgear and controlgear products. In this article, we will discuss the purpose of these standards, key requirements, and features.

Purpose of UL 60947-8-2020:

UL 60947-8-2020 is an international standard that focuses on setting guidelines for manufacturers, installers, and users of low-voltage switchgear and control gear products. The primary objective of this standard is to establish compliance with safety standards, minimizing risks to people and property.

Key Features and Requirements:

UL 60947-8-2020 provides guidelines for the design, manufacture, and testing of low-voltage switchgear and control gear products. The standard outlines key features and requirements that manufacturers must ensure their products meet. These requirements are divided into two categories: essential requirements and optional requirements.

Essential Requirements:

The essential requirements are non-discretionary, meaning they must be met by the manufacturer. These requirements are necessary for the product to function safely and effectively. Examples of essential requirements include:

* The product must be designed to operate without overheating

* The product must be designed to withstand environmental conditions, including high and low temperatures

* The product must be designed to withstand electrical, mechanical, thermal, and other stresses

* The product must be designed to operate for the intended service life

* The product must be designed to minimize the risk of electrical shock

Optional Requirements:

The optional requirements are discretionary, meaning they are not mandatory but are highly recommended by the manufacturer. These requirements can enhance the safety, reliability, and performance of the product. Examples of optional requirements include:

* The product must have a user-friendly interface

* The product must have a suitable cabinet design

* The product must have a thermal protection device

* The product must have a mechanical strength of at least 300 N/mm2

Conclusion:

UL 60947-8-2020 is an essential standard for manufacturers of low-voltage switchgear and controlgear products. It provides a framework for ensuring the safety, reliability, and performance of these products. By meeting the essential requirements outlined in the standard, manufacturers can guarantee that their products are designed and manufactured to meet industry safety standards. Compliance with UL 60947-8-2020 is essential for the safety and reliability of low-voltage switchgear and controlgear products.
