Introduction to UL certified motors for North America
For machine export to North America, UL certification is relevant for market acceptance, even if it is not always legally required in the USA, unlike CE in Europe. Insurers often require a UL listing; if it is missing, problems may arise during commissioning or with authorities, e.g. weeks of delays. Modern drive technology must take this into account.
UL testing aims to minimize risks of fire and personal injury. UL compliant motors are therefore essential for product safety in North America. A UL mark signals compliance with building regulations and builds customer trust. The choice of suitable motors, especially a suitable UL certified motor for North America, is crucial.UL Listing vs. UL Recognition: A crucial difference
UL Listing (UL Listed)
“UL Listed” confirms that the end product (e.g. ventilation unit with motor) is UL tested and meets safety standards. This ensures that a packaging machine manufacturer secures US approval for their facility. UL listing applies to the ready-to-use product.
- UL Listed: Confirms that the end product (e.g. ventilation unit) is UL tested and meets safety standards.
- UL Listed application: Applies to the operational product and ensures, for example, approval of facilities in the USA.
- UL Recognized: Refers to pre-evaluated individual components (e.g. insulation systems) that are incorporated into end products.
- UL Recognized flexibility: A motor may include UL recognized parts without the entire motor being classified as “Listed”. This is relevant for systems that integrate a UL approved motor for the North American market .
- cURus marking: Signals the acceptance of products or components in both the USA (by UL) and Canada (by CSA).
- Advantage cURus: Simplifies market access for manufacturers and saves exporters cost and time through a single certification mark for both countries.
UL Recognition (UL Recognized)
“UL Recognized” applies to pre-evaluated individual components (e.g. motor insulation system, File No. E231380) for end products. A motor can contain UL recognized parts without being overall listed. This is an important aspect when it comes to components for a UL approved motor for the North American market and is relevant when purchasing electric motors. Importance of the cURus marking The cURus mark signals product/component acceptance in the USA (UL) and Canada (CSA). It facilitates market access for manufacturers with a certification mark, saving exporters (e.g. of machine tools) costs and time, especially when they
