Can a connector that is UL Recognized under UL CCN ECBT2 to UL 1977 be used in AV/ICT equipment investigated to CSA UL 62368-1 without further investigation of the connector to a CSA component connector standard?

More specifically you asked:  I have an IT product for US/Canada with a connector on the backplane that is UL Recognized under UL's CCN ECBT2 and the UL1977 Standard but not Recognized under UL's CCN ECBT8 to the Canadian CSA C22.2 No. 182.3. The connector is NOT certified for Canada by CSA or other Canadian certification bodies. I wonder how the IT product will be accepted by the various Certification organizations for US/Canada Listing/Certification to UL/CSA 62368-1 if the connector is only Recognized by the UL1977 Standard?


In response, UL 1977, 'œComponent Connectors for Use in Data, Signal, Control, and Power Applications,' is listed in the CAN/US National Difference from IEC 62368-1 that is composed as 'œAnnex DVG, (normative), UL and CSA component requirements (alternative).'  Annex DVG states at its beginning, 'œIn the U.S. and Canada, any of the following equipment, components, or subassemblies that comply with either the specified UL or CSA Group standards are considered as an acceptable alternative to the requirements of IEC 62368-1.' 


Therefore, for a CAN / US certification to CSA UL 62368-1 a certification of a connector to UL 1977 under ECBT2 and used per its ratings can be used without further certification to a Canadian Standard for connectors.


As different applications and their specific details can have expanded considerations, please feel free to reach out to UL for a more detailed discussion via your established UL Account Manager, or via https://62368-ul-solutions.com/contact-ul.html .
