Hello,

One of the fuses in my brymen blew (dont ask me how because i have no idea, I did not put any big loads on it). Shopping for it I find the bussmann dmm-b-44/100-r for prices that range from 6 euros (aliexpress, ebay) up to 50 euros in specialized shops. Now, can someone tell me how much I should expect to pay for it ?

Thanks!

As long as amazon is seller and shipper you will definitely get no fake, so you are fine. However, they have a minimum order quantity. Generally speaking a good fuse by Bussmann costs between 10 Euro and 12 Euro. Anything below is probably fake...

The last time I ordered from another shop "Bussmann", I got "Littlefuse", but I accepted it.


My last purchase, you probably have to change ".de" into your country:


11A






minimum order quantity 3 times: á 11,99 Euro

440mA






minimum order quantity 5 times: á 10,99 Euro

Cheers!  ;)

The strange part is that Fluke branded fuses are cheaper. https://www.fluke.com/en-us/product/accessories/fuses/fluke-11a-1000v-fuses-5-pack $47 for a pack of 5. All fuses on Aliexpress are counterfeit. You may get some real ones on ebay if seller acts as re-shipper who orders them from distributor. On Amazon, unless it's amazon itself or some reputable company selling on amazon, most likely they will be fake. I suggest SIBA 5021006.0.44 and 5019906.11 as the cheapest options  https://www.tme.eu/en/details/5021006.0.44/fuses-10-3x38mm-fast/siba/5021006-0-44 https://www.tme.eu/en/details/5019906.11. Distributors don't sell them at ridiculous prices which are close to some multimeters with those fuses inside. Also they actually have 3 times better maximum interrupting current rating.

PushUp:
Just to prevent the next blown 440mA-fuse, as it is annoying to pay so much money for a new one:

Even with small current, you often also have to deal with "inrush current". The "MAX 0.6A" on your meter are misleading. You should be way under 400mA, to be on the safe side the next time. It might be tricky to estimate from A-measurement to mA-measurement, that it is safe, to change the test leads, so that you might want to use the record function in A-mode to capture some spikes about 0.4A, which does not survive your expensive 440mA fuse, before switching to the mA range itself...

However, I don't know if the record function of the Brymen is also able to measure 250µS to capture peak values like the Fluke 289 does for example?

That is the reason, why I prefer using my Gossen Metrawatt, when measuring current and yes, I don't care about the doubled used common, as it is precise enough for me and saves me a lot of money, as I will never ever have to buy a 440mA fuse again, because the Gossen Metrawatt does not have one! ;-)





Cheers!  ;)

Another option is to buy them from Brymen
