content: I am not having good luck finding fuses for my uni-t a-bf CS618A+ dmm. Either the size is incorrect or the price is very high.Mainly I am looking for a 15-20A fuse (meter is 20a max) and I believe the size is 6x25mm.

content: For the CS618A+ DMM, which I understand is a rebranded UT61E+, see the discussion on fuses at this pagehttps://www.eevblog.com/forum/testgear/new-uni-t-ut61-series-(ut61e)/100/As noted there, the ceramic 6x25mm fuses do not have the suitable voltage or breaking current rating for the supposed CAT rating of the meter. Just something to be aware of, as I hope you are not using this in CAT III or higher application.If the original fuse in the DMM was the stated AsianFuse AF63C (BS1362 compliant) then that is probably only 240V 10A rated.This type of fuse is relatively common as BS1362 fuses are in almost every UK power plug. They will generally be a bit more expensive than a glass fuse, but are still way cheaper than a "real" 11A DMM fuse like the one KungFuJosh linked.

content: I don't use it for CAT iii and the original fuse was indeed an Asiafuse 10A. I did want to use a higher amp rating (15A or 20A) fuse since the meter range is up to 20A. But now I am doubtful whether I should do that.

content: Quote from: KungFuJosh on July 04, 2025, 02:02:57 amI don't think those will fit the OP's meter.However, for those that are in the market for the full size DMM fuses, there is a slightly lower cost source than most on AliExpress. These guys sell genuine Cooper Bussmann fuses for a reasonable price. They also sell Hioki. Kyoritsu, CEM and UNI-T instruments and are on the up and up.11A:https://vi.aliexpress.com/item/1005009304611572.html400mA:https://vi.aliexpress.com/item/1005009303686902.html

content: Fuses on Aliexpress can be a crap shoot.If you get them from aliexpress make sure you get an extra one and test it to confirm it blows around 2x amps more or less.There's lots of fakes and mislabeled stuff.With fuses it's super easy to make counterfeit versions and get away with it because products work fine with a fuse that's just a piece of wire, or a much higher rating than it's supposed to be. There's a large delay to extract profit before the scam is detected.Same applies to polyfuses.

content: If you're using a meter in dangerous places then pay the bleeping $15 for a real fuse. What's the point in trying to save $3?Second: Learn to use your meter. Follow proper procedure and you'll never blow a fuse.If you can't do that then get a current clamp and a meter with no current range or fuses in it.

content: Quote from: Psi on July 07, 2025, 08:43:42 amThese ones aren't. I've used them and have a couple of each still knocking around. The dealer is a reputable dealer selling mid to high end equipment. They are not going to be selling"Shenzhen Special Lucky Magic Fuse Smoke"fuses just so they can toast their reputation. It's not all that hard to learn how to shop on AliExpress and do well. Just check out the vendor, their products and their ratings.
