What is UL 60947-2:2020?

UL 60947-2:2020 is an international standard for low-voltage switchgear and controlgear. It specifies the general requirements for low-voltage switchgear and controlgear assemblies intended for use in electrical power distribution systems. This standard was published by Underwriters Laboratories (UL), a global safety certification company.

Scope and Objectives

The scope of UL 60947-2:2020 includes electrical equipment such as circuit-breakers, switches, disconnectors, and contactors. It applies to low-voltage switchgear and controlgear assemblies designed for rated voltages not exceeding 1000V AC or 1500V DC. The objectives of this standard are to ensure the safety, reliability, and performance of these electrical devices.

Key Requirements

UL 60947-2:2020 sets out various requirements that must be met by manufacturers and suppliers of low-voltage switchgear and controlgear. These requirements cover aspects such as temperature rise limits, dielectric properties, short-circuit withstand strength, mechanical operation capability, and protection against electric shock.

The standard also addresses issues related to environmental conditions, including tests for resistance to heat, humidity, and low temperatures. Additionally, it provides guidelines for marking, documentation, and installation instructions to ensure proper handling and usage of the equipment.

Benefits of Compliance

Complying with UL 60947-2:2020 offers several benefits to manufacturers, suppliers, and end-users of low-voltage switchgear and controlgear. Firstly, it ensures that the products meet stringent safety requirements, reducing the risk of electrical hazards and accidents. Compliance also improves product quality and reliability, enhancing customer satisfaction and brand reputation.

Furthermore, adhering to this standard facilitates market access, as UL certification is widely recognized and accepted by regulatory authorities and customers globally. It opens doors for businesses to expand their reach and increase competitiveness in the electrical equipment industry.

In conclusion, UL 60947-2:2020 is a significant international standard that sets requirements for low-voltage switchgear and controlgear assemblies. Complying with this standard ensures safety, reliability, and performance of these electrical devices. Manufacturers and suppliers who meet these requirements enjoy various benefits, including improved product quality, customer satisfaction, and market access.
