As a Danish manufacturer of motor controllers and electronic contactors, Eltwin has been categorized in accordance with UL 508 (UL Standard for Safety for Industrial Control Equipment). UL 508 defines the requirements for the start, stop, regulation control and protection of electric motors and associated equipment. We have also elected to have our products tested in accordance with Canadian safety standards. We have therefore been granted permission to equip our products with the "C UL US LISTED" mark.
One often refers to a product as "UL-approved", but this is actually incorrect. One must instead refer to the types of certification, which are
1. UL Listed
2. UL Classified
3. UL Recognized Component
The marking indicates which type of certification the product has.
UL is exclusively a product certification, which is why the products are subject to inspection. In order to check that the certified products continue to fulfil the safety requirements placed upon them, UL regularly carries out unannounced factory visits, including inspection of production and testing, and has the authority to take samples for testing in its own laboratories.
As supplier to Eltwin's UL approved products, you will be asked to supply documentation for approval, e.g a CoC.
