UL 61800-5-1: A new UL standard for drives and what you need to know

Webinar: UL 61800-5-1: A new UL standard for drives and what you need to know

Development and Certification Manager – Drives Siemens Industry, Inc.

An old UL standard, UL 508C for low-voltage adjustable speed drives (ASD) or variable frequency drives (VFD), was obsolete and withdrawn by UL on February 1, 2020. This standard was replaced with a newer UL standard UL 61800-5-1, originally published in June 2012. The withdrawal of UL 508C has greatly impacted the industry as many drive manufacturers have not taken the initiative to update their product designs to this newer standard.


Join Siemens as we provide an expert’s perspective on what you need to know if you are a user, a panel builder, a manufacturer of motor control centers (MCC) or an OEM. The webinar also highlights strong benefits of using UL 61800-5-1 certified drives.


Benefits of attending:

  • Discover the background and motivation of development of UL 61800-5-1
  • Understand significant differences between the drives certified according to new UL 61800-5-1 and obsolete and withdrawn UL 508C, together with the great benefits of using drives listed according to new UL 61800-5-1
  • Learn about the impact to the industry as result of this withdrawal of UL 508C last year – especially what you need to know if you are a user or a panel builder or a MCC builder or an OEM who use drive as a component in your product
  • Discover how can you determine the compliance of a drive with UL 61800-5-1
