What is UL 61058-2-2020?

UL 61058-2-2020 is a professional technical standard that defines the requirements for switches for appliances. It is developed and published by Underwriters Laboratories (UL) in accordance with the safety and performance requirements established by NEMA (National Electric Code). The standard provides extensive guidance and criteria for manufacturers, testing laboratories, and regulatory bodies to evaluate switches used in various appliances, industrial equipment, and commercial devices.

Key Changes in UL 61058-2-2020:

The latest version of UL 61058-2-2020 was published in February 2020, and it covers a wide range of switches, including those found in household appliances, industrial equipment, and commercial devices. The standard has several key changes compared to the previous version, including:

Increased Safety: The standard has several new requirements designed to enhance the safety of users. For instance, the standard requires switches to have a more detailed failure mode and circuit description to help engineers identify potential hazards.

Environmental Stresses: The standard has new requirements for switches to withstand environmental stresses, such as high temperature, low temperature, and voltage.

Improved Performance: The standard has new requirements for switches to perform consistently and reliably, including high voltage and current ratings.

Compatibility with Emerging Technologies: The standard is designed to new technologies, such as IoT (Internet of Things) and edge computing, to ensure that switches remain safe and reliable in the evolving electrical landscape.

Key Requirements of UL 61058-2-2020:

To comply with UL 61058-2-2020, manufacturers must ensure that their switches meet the following key requirements:

Electrical Safety: The switch must be designed to prevent electrical hazards, such as electrical fires, electrocution, and other injuries.

Performance: The switch must perform consistently and reliably under various environmental conditions, including high and low temperatures, high and low voltage, and rapid switching speeds.

Safety Protection: The switch must have built-in safety features, such as overcurrent protection, overvoltage protection, and thermal overload protection.

Interoperability: The switch must be compatible with other electrical devices and systems, including other switches, motors, and control gears.

Documentation: The manufacturer must provide clear and concise documentation for their switches, including a user manual, wiring diagram, and specifications.

Conclusion:

UL 61058-2-2020 is a crucial set of guidelines and regulations that provide comprehensive requirements and testing procedures for switches used in various electrical devices. Compliance with this standard is essential for manufacturers, designers, and engineers involved in the production and development of electrical switches.
