Review: Correct replacement for Fluke 87 V meter - Correct version fuses for my Fluke DMM. Used to be hard to find these fuses in years past but glad they were available on desertcart. I do wish they weren't so expensive but they have to meet some fairly tight criteria and I imagine they aren't produced in large quantities like common AGC or similar fuses. Just pay attention to what the circuit is you are working on and if you can use an inductive ampere meter will save you buying these. Review: Good value - Great value. They fit my fluke meter and everything I expected in a fuse… ## Features - Electrical Ratings: 440 mA and 1,000 Volts AC/DC - Fuse Size 1.375" X 0.41" - Specifically Designed for use in Multi-Meters - Common Part # 943121 - Packaging Contains Two DMM-44/100 Fuses ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QLHG5P7 | | Best Sellers Rank | #384,039 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #895 in Cartridge Fuses | | Brand Name | QSU | | Customer Reviews | 4.8 4.8 out of 5 stars (426) | | Manufacturer | Bussman | | Material Type | Melamine | | Maximum Current | 440 Milliamps | | Model | 2-DMM-44/100 | | Mounting Type | Holder | | Voltage | 1000 Volts | ## Product Details - **AC Adapter Current:** 440 Milliamps - **Brand:** QSU - **Material:** Melamine - **Mounting Type:** Holder - **Voltage:** 1000 Volts ## Images ![DMM-44/100 Multi-Meter Fuse 440mA 1000V 943121 (2 Pack) QSU - Image 1](https://m.media-amazon.com/images/I/71rFm2MedbL.jpg) ![DMM-44/100 Multi-Meter Fuse 440mA 1000V 943121 (2 Pack) QSU - Image 2](https://m.media-amazon.com/images/I/51kedC+-tVL.jpg) ![DMM-44/100 Multi-Meter Fuse 440mA 1000V 943121 (2 Pack) QSU - Image 3](https://m.media-amazon.com/images/I/61G7dpj4vEL.jpg) ![DMM-44/100 Multi-Meter Fuse 440mA 1000V 943121 (2 Pack) QSU - Image 4](https://m.media-amazon.com/images/I/41r7JJjEfoL.jpg) ![DMM-44/100 Multi-Meter Fuse 440mA 1000V 943121 (2 Pack) QSU - Image 5](https://m.media-amazon.com/images/I/61p54aTN8IL.jpg) ## Questions & Answers **Q: can i sue this with fluke 28-2 DMM** A: Yes, in the 28 manual, shows 0.440 A, 1000 V ## Customer Reviews ### ⭐⭐⭐⭐⭐ Correct replacement for Fluke 87 V meter *by A***N on January 19, 2024* Correct version fuses for my Fluke DMM.
