On a Bussmann DMM-series multimeter fuse, the B indicates it has a bump or raised section on one of its end caps, which is designed to prevent it from being inserted into the wrong slot or holder. These are considered "extra safe" fuses intended to prevent incorrect installation and ensure the multimeter's safe operation.
