What is UL 60947-5-2020 ?

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 standard for low-voltage switchgear and controlgear products. This standard is designed to provide a standardized framework for manufacturers, regulators, and end-users to evaluate and compare these electrical devices. 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.

What is 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 sets guidelines for manufacturers, installers, and users of low-voltage switchgear and control gear products. It aims to minimize risks to both people and property, and compliance with this standard guarantees that the products are designed and manufactured to withstand electrical, mechanical, thermal, and other stresses.

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

UL 60947-8-2020 has several key features and requirements that manufacturers and users must meet to ensure the safety and performance of their products. 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 both users and 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, including short-circuits, over-currents, and voltage drops.

Environmental Strain: The standard outlines the environmental conditions that the switchgear and controlgear products can withstand, including temperature, humidity, and vibration.

Electrical Interference: The standard defines the sources of electrical interference that may affect the switchgear and controlgear products, and provides guidelines for minimizing the impact of these interference sources.

Traceability: The standard requires manufacturers to provide a traceable record of their products' design, testing, and inspection, ensuring that they meet the specified requirements.

Conclusion:

UL 60947-8-2020 is an essential standard for manufacturers and users of low-voltage switchgear and controlgear products. It provides a framework for evaluating and comparing these products, ensuring that they meet industry safety standards and perform consistently in various operating conditions.
