UL 61800-5-1

Nikunj Shah - Development and Certification Manager - Drives, Siemens Industry, Inc.

An old UL standard, UL 508C, for low-voltage adjustable speed drives was obsolete and withdrawn by UL on February 1, 2020, and replaced with the newer standard UL 61800-5-1, which was originally published in June 2012. The withdrawal of UL 508C has greatly impacted the manufacturing industry and has raised many questions among drive users. This presentation provides an expert's perspective on what you need to know about UL 61800-5-1 — especially if you are a drive user, a machine builder, a panel or system manufacturer, or an OEM. We will also highlight the numerous benefits of using UL 61800-5-1 certified adjustable speed drives.
