What is UL 60947-14-2020 ?

Title: Unlocking the Benefits of UL 60947-2:2020 for Low-Voltage Switchgear and Controlgear Products

The safety and efficiency of electrical installations are critical factors that influence the overall quality of life. The design, construction, and testing of low-voltage switchgear and controlgear products are directly linked to these factors. To ensure that these products meet industry safety standards, Underwriters Laboratories (UL) publishes the latest version of UL 60947-2:2020. This standard is a comprehensive guide for manufacturers, regulators, and end-users to evaluate and compare low-voltage switchgear and controlgear products.

Key Requirements of UL 60947-2:2020:

UL 60947-2:2020 is designed to establish guidelines for the design, construction, and testing of low-voltage circuit breakers. The primary objective of this standard is to ensure that the circuit breakers conform to certain safety criteria and exhibit desired functionality. The key requirements of UL 60947-2:2020 include:

Safety Integrity: The standard requires that circuit breakers have an inherent safety feature, which ensures that they can detect and interrupt the flow of electrical current in case of an overcurrent.

Electrical Characteristics: The standard specifies the electrical characteristics of circuit breakers, including their voltage rating, current handling capacity, and short-circuit protection.

Performance: The standard outlines the tests that must be performed on circuit breakers to verify their performance, such as their ability to withstand voltage surges and current spikes.

Environmental Stability: The standard requires that circuit breakers be able to withstand various environmental conditions, including high temperature, low temperature, and high vibration.

Electrical Overvoltage: The standard specifies the voltage levels at which the circuit breakers must be able to operate without causing damage.
