Are these plugs and receptacles UL listed?
Yes, they are listed to UL 2682 and UL 1682.
Are these devices CSA listed?
Without pilots, they are CSA listed to 182.1. The CSA listing with the pilots is currently pending CSA review of the UL file. The approved CSA listing with the pilot circuit is expected within the next 2-3 months.
What’s different about the DSN20 pilot contacts?
Unlike other DSN and DS products, the DSN20 pilot contacts are only on the receptacle side and create a continuity loop that is completed when the plug is connected to the receptacle. The pilot circuit is in the interior of the receptacle and is not visible to the user once the device is installed.
When will these enhanced plugs and receptacles be available?
The enhanced hp rated DSN20 devices are currently available for shipment. View the updated listings in the online MELTRIC catalog at meltric.com.
