## Questions & Answers

**Q: Is this a replacement for littelfuse flu 44/100?**
A: Looking at the spec sheets I would say yes.  They are both the same size with the same specs and are specially designed for multimeter protection.  There are also 11A versions of these fuses that are the same diameter but are a little longer.

**Q: The description says dmm 44/100 but the picture shows dmm-b- 44/100. which is it?**
A: The fuses I received were the dmm-b-44/100 variety.  According to one reference I found the only difference between the variety that have -b and those that don't is that the -b variety  are those sold to Fluke and those without are sold to the general market.  There are no other physical differences.

**Q: What are the dimensions of this item**
A: Dimension: 34.9 mm (1.375 In.) L x 10 mm (0.406 In.) D

**Q: Will this replace my fluke 85v 400 milliamp fuse?**
A: To the best of my knowledge, yes. I only use Fluke handheld multimeters and this is why I bought these fuses.

### ⭐⭐⭐⭐⭐ Theses are used in Fluke 87V DVM
*by M***S on January 24, 2023*

These are used in Fluke 87V digital volt meters. They are real Cooper-Bussmann DMM-B-44/100 DMM Fuses. They were bulk packed and arrived in great condition. Seller was prompt in shipping and they arrived when they were supposed to.

### ⭐⭐⭐⭐⭐ OEM fuses for Fluke DMMs

Perfect fit for the Fluke DMMs. Always good to have a few 400 mA fuses on hand!

### ⭐⭐⭐⭐⭐ Perfect Replacement Fuse For Fluke 174 Multimeter
*by M***Y on November 29, 2020*

Perfect replacement fuse for my Fluke 174 multimeter. The new fuse is shown on the right. I was initially uneasy based on the slight difference in the image and part number online, but overall it was an exact fit. Five fuses should last awhile but will order again if needed.
