Specific Safety Requirements for AC Semiconductor Motor Controllers and Starters: UL 60947-4-2


Description

Review the basic safety requirements in UL 60947-1, the Standard for Low-Voltage Switchgear and Control gear as they pertain to AC Semiconductor Motor Controllers and Starters, and gain an in-depth understanding of the safety requirements of UL 60947-4-2, the Standard for AC Semiconductor Motor Controllers and Starters. The requirements that apply to AC solid state controllers come from a combination of both standards and the course content corresponds with the release of UL 60947-4-2 that will replace UL 508. This two-day course, designed for product designers and product and regulatory compliance engineers, also covers the major topics from UL 60947-1 and some of the major differences between it and UL 508 and IEC 60947-4-2.
