Hello, The QOC40U is the catalog number for the cover. In order to determine the catalog number for the interlock kit, you need to provide the catalog number and series of your load center. The article FA274608 in our FAQ system can help you locate the catalog number and series of your load center. Regards, Schneider Electric Customer Care.
