What is UL 60947-6-5:2020?

The UL 60947-6-5:2020 standard, also known as the Low Voltage Switchgear and Control Gear - Part 6-5: Multiple-function equipment - Control and protective switching devices (or MCP for short), is an international standard that sets requirements for control and protective switch devices used in multiple-function equipment. It is published by Underwriters Laboratories (UL), a globally recognized independent safety science company.

Scope and Application

The scope of UL 60947-6-5:2020 covers control and protective devices used for switching and controlling electrical circuits within various applications, including industry, buildings, infrastructure, and power distribution systems. This includes equipment such as motor controllers, contactors, circuit breakers, switches, and more.

This standard should be used by manufacturers, designers, installers, and users of control and protective switchgear to ensure the proper functionality, interoperability, and safety compliance of their products and installations.

Key Requirements and Compliance

UL 60947-6-5:2020 sets out specific performance and safety requirements that control and protective switchgear must meet in order to comply with the standard. These requirements cover aspects such as electrical ratings, environmental conditions, mechanical durability, temperature rise, dielectric properties, fault protection, and more.

Manufacturers need to thoroughly test their products and provide evidence of compliance with these requirements in order to obtain UL certification. This certification assures users that the switchgear they are using meets the necessary safety standards and has undergone rigorous testing.

Benefits of Compliance

Complying with UL 60947-6-5:2020 offers several benefits to manufacturers, designers, installers, and users of control and protective switchgear. Firstly, it enhances the overall safety of electrical installations by ensuring that the devices used are reliable and capable of effectively controlling and protecting circuits.

Furthermore, compliance with this standard promotes interoperability between different manufacturers' equipment, allowing for seamless integration in various applications. It also helps manufacturers demonstrate their commitment to quality and safety, enhancing market trust and competitiveness.
