What is UL 60730-1?


UL 60730-1 is a widely recognized safety standard developed by Underwriters Laboratories (UL), an independent testing and certification organization. This standard specifically addresses the safety requirements for automatic electrical controls used in household appliances, commercial equipment, and industrial products.

Purpose and Scope

The main purpose of UL 60730-1 is to ensure that automatic control devices meet specific safety criteria during their design, manufacturing, installation, and use. It covers various aspects related to electrical and electronic controls, including temperature, pressure, flow, and mechanical controls, among others. By complying with this standard, manufacturers can guarantee the safety and reliability of their products.

Key Requirements

UL 60730-1 sets forth several important requirements for automatic controls. These include:

Protection against electrical shocks: The standard specifies insulation, grounding, and protection against electric shocks.

Protection against fire hazards: It outlines measures to prevent ignition, overheating, and short circuits.

Temperature and pressure limits: The standard establishes safe operating limits for temperature and pressure controls.

Electromagnetic compatibility: It addresses the interference caused by electromagnetic fields and ensures controls do not malfunction due to external influences.

Durability and mechanical strength: UL 60730-1 requires controls to withstand mechanical stress and environmental factors.

Certification Process

To obtain UL 60730-1 certification, manufacturers must meet specific testing criteria and submit their products for evaluation by UL. The evaluation process includes inspection of the manufacturing facilities, product testing in a controlled environment, and review of technical documentation.

Once a product successfully passes all tests and inspections, it is granted UL 60730-1 certification, and manufacturers can display the UL mark on their products as a symbol of compliance with safety standards.


UL 60730-1 plays a vital role in ensuring the safety and reliability of automatic electrical controls used in various applications. By adhering to this standard, manufacturers can ensure that their products meet stringent safety requirements, providing customers with peace of mind and reducing the risk of accidents or malfunctions.
