Question 15A(T) 20mm glass Wire-ended fuses

Anyone know from where I can purchase these? I need to replace one in a Halfords Battery Charger. As it's an internal fuse I won't be able to get one from them. On eBay I can only find ceramic bodied wire-ended 15A Fuses, which might be OK, but I'd rather fit the correct type if possible.

Have you tried Halfords ? I think you might find them in hardware packs.

If you do not need 20, you can find them on ebay (and elsewhere) if you search for ''0218015.MXEP'' or Littlefuse 0218015.MXEP.

Hi, in theory the ceramic body type should be superior to a glass bodied type.

You'll have better luck looking for Littelfuse 0218015.MXEP

Thanks, everyone for your help. I'll check out the links and decide which to buy.

You could buy a single blade fuse holder and solder it into the board.
It will make it easier to change next time and spares will to be to hand in any vehicle related location.

Or, as I later thought, solder in a 20mm fuseholder, of which I have several, and fit a standard clip-in 15A fuse, subject to there being room on the PCB to fit either type of course.

One thing to be aware of is that the maximum current rating of most 20mm fuseholders is usually 10A or less.

Two Comments- On checking again the ceramic 15A Fuses to which I referred are Quick Blow not T - Looking at snowman al's and Herald 1360s posts (#4 & 6) The numbers given (Littlefuse 0218015.MXEP) appear identical. As I don't need 20 of these, and as, having looked at the PCB involved there is no room to fit any kind of fuseholder, I'll search on eBay and order a small quantity from a seller on there. Rapid, Cricklewood & CPC don't stock them, and I need to get some within a week, which rules out ordering from an overseas source.

I think if I were breaking 15A I would want to insist on a ceramic-bodied fuse.

Depends on the voltage available and the prospective fault current vs the fuse ratings but at that current a 20mm fuse will be a bit marginal.

All I can say is that the manufacturer fitted a wire-ended 20mm glass 15A(T) Fuse, and there isn't really room to fit anything else. As I previously noted the fuse is in the secondary winding, between the transformer winding and the rectifier. The charger is a nominally 12 volt type so the voltage is no more that 18v off load. The charger's owner told me he accidentally shorted the positive & negative clips, which is what blew the fuse, and, whilst there is no way to guarantee that won't happen again, I see no reason to fit a higher-rated or different type of fuse, other than the fact that, should it blow again, the charger will have to be opened to replace it. Refugee, AFAIK, automotive blade fuses ar Quick Blow unless anyone knows differently.

Two or three years ago someone asked me if I could repair a Halfords charger, it was in a grey plastic case with a label on it saying something to the effect of ' no user replaceable parts within '.having gained access to the internals ifound a blown wire ended fuse. I replceced it with a 1'' glass fuse to which I soldered some stout - 16 swg ? - copper wire, and soldered the other ends after passing the wires through the existing holes to the PCB.

I have some 15A(T) wire-ended fuses on order now, so will fit one when they arrive, EG. No doubt a 20 or 32mm fuse could be wired to the print side of the PCB. This charger is in a black plastic case with 3 LEDs, a switch to select Lead-Acid or Gel batteries and a 35A Blade fuse in/on the front panel, plus what appears to be a spare 20A Blade fuse in the removable cable holder at the back. Four of the case screws are regular types, whilst the fifth, center screw, is one with a 'pip' in the middle needing a special screwdriver to turn it.
