What is UL508?

UL 508 is a safety standard published by Underwriters Laboratories (UL) that covers industrial control equipment. It specifies the requirements for the design, construction, and performance of industrial control panels and their components. Compliance with UL 508 demonstrates that the equipment meets recognized safety standards and is suitable for use in industrial environments, helping to ensure the safety of personnel and equipment. It's commonly used by manufacturers of industrial control panels to obtain UL listing, which is often required by regulatory authorities, insurance companies, and end-users.
