Beware when buying DMMs on ebay, fuses ain't cheap!

[tooki]

The red one says 10kA, while the purple one is 20kA. That's quite an improvement. 

Bussmann datasheet says 20kA is correct for the DMM-B-11A.

http://www.farnell.com/datasheets/287359.pdf

The datasheet also says that the DMM-B-11A is slightly longer than the 10K version. Look carefully at the image where the 2 are shown horizontal next to one another. The purple (DMM-B-11A) is slightly longer. Perhaps these are 2 different fuse types.

The pictures clearly show they're two different fuses. The red one is the 440mA, the purple the 11A. (Intended for a Fluke 87V.) The seller sold them as a set.

Does the consensus seem that the red one is real and the purple one is fake?

Dave, you want me to mail you the fake one for dissection? I don't know enough about these for it to be worthwhile for me to dissect it myself. (Have you gotten mail from Switzerland before?? )

The purple one is certainly fake.

It's possible the red one is real but the fact it was sold to you with a fake puts that in doubt.

You should return them to the seller and ask for a refund. If they refuse go to ebay and use this thread as evidence.

Anyone know if the 'REAL' fuses have a difference in weight (0.5g) (5.89g vs 6.37g)?

I purchased all of them from a seller located in China.



please advise,

Thanks

If you are buying a new multimeter, it is always best to buy at least one spare set of fuses at the same time.

Just like car replacement parts.

Open one up, see if they're filled with sand or not.
And next time, don't buy fuses from China.

They look fake. Genuine ones look like this:

Except completely different marking, metal caps are crimped not like on genuine fuses and look awful.

About once every 2 years I slip up and blow a fuse, so I only keep one spare handy for when I need it.

Last time I bought 2 from Testpath:
https://www.testpath.com/Items/Fuse-11A-1000V-10-x-38mm-Fast-Acting-116-230.htm $9.95

they accept all credit cards for US and Canada buyers,  but international orders have to pay by wire or money order. They ship to Canada for just $7.95 (same as the US) and there are no additional handling fees, whereas international orders have $10.00 tacked on. They almost treat Canada like the 51st State   Good to see vendors realizing that it's easy to do business with Canadian buyers.

You can get 2 from Aliexpress for about $11. These actually look legit, but who knows. I would hate to bet my life on it if I was an electrician, but it's probably OK for my bench uses.  I'd like to crack one open, but then you can't use it and your cost goes up, so it's better to just buy from a known dealer anyways.
