The R probably stands for Rejection.  Between Rectifier & Safety T Plus in the link below.

Just replying here in case anyone else finds this thread as I did, searching for clarification on these DMM fuses.  I received the following response directly from Fluke yesterday:

“The DMM-11A is an older version of the DMM-B-11A. The DMM-11A-R and DMM-R 0.44 refer to a RoHS compliant part.

“According to the UL Cert from Cooper Bussmann the DMM-11A, DMM-B-11A and DMM-11A-R fall under the same UL cert. Likewise for the DMM, DMM-B, DMM-R 0.44 fuse.

“It looks like over the years they have changed the model number in the catalog and updated the cert with the new model, but kept the same ratings and UL certification.”

So, in case anyone besides me is still uneasy about using the “B model” versions of these fuses, the horse’s mouth says they should be fine.

Sorry for bumping such an old topic.
