We recommended using 03480870Z as alternative. - Processed via Future PCN 50681.Additional due lack of interest the certifications were dropped for the 344 and 348 series; because of that all the marking logos will be remove from the body and packing labels. There are no changes in form, fit, function, or materials to our part. The changes are the elimination of the UL and CSA logos and from the holder's plastic body.
