Review: Review of Fluke 943121 440mA 1000-V Replacement Fuse - I am satisfied the fuse works properly with my Fluke 15B.
Review: Right fuse for my Greenlee - It's the right part, right price. I haven't blown a fuse yet, but wanted a backup. Local electronics store wanted 17$ for the same fuse (not radio shack). Feels like flat out robbery at that price. I have a Greenlee DM-65, and it uses the same small amp fuse as many flukes, the 1000V, 440 mA, 10kA IR. From the product details, I wasn't clear on IR rating. Didn't seem to say. Although it may be overkill, I wanted to stay with manufacturer recommendations. Turns out this is in fact 10 kA IR.
