No explanation of what it does, but the reviewers are very happy.
Snake oil anyone?

Yup, a trap for the unwary or the stupid.

There's always been a lot of talk of higher specification power cables and plugs for high end Hi-Fi components..... the problem as I see it is that putting a higher quality bit of wire, plug or fuse on the end of most household ring mains or radials is laughable when you look a bit closer at how poor those installations are - especially if Mr (Mrs?) jack of all trades handyman has been busy bodging on spurs etc all over the place.

If you read that 'magazine review' the website talks about (actually just someone's blog), in the comments you'll see that they are actually Bussmann fuses (£1.90 for 10 at Toolstation) that have been given the company's 'Super Burn' treatment. ::)
Details of this treatment are not disclosed, but presumably they involve applying a black and silver self adhesive label followed by bringing the fuse into close proximity with someone who has more money than sense.
It's probably worth pointing out at this juncture that placebos have a greater effect the more expensive they are to purchase :y

Might replace all my cheap fuses when my Nigerian investment money gets transferred over
thanks for the link :)

Bargain a twice the price ..... ::) ::)

It's Russ Andrews (= expensive snake oil for the gullible). ;D Makes Bose stuff look well engineered and fantastic value. :-X

A 13 amp fuse is just that, to protect a cable up to that rating.
You would be bloody mad to think you could somehow "up-grade cable" and exceed 13 amp loading just because these fuses are rated "Super fuse"!! ::) ::) ::) ::)

One would think so, but on my degree course a large part of one module was taken up with "fuses" !! In the lab we could consistently get a 13 amp fuse to take up to 25 amps without blowing, especially if the current was increased slowly, pulsed and cooling applied to the "fuse" !! So called "fast blow" fuses would regularly fail at around 11 amps !
Remember .. a fuse "blowing" is simply the wire overheating and melting ... the quality of the wire, the rate of heat dissapation v the rate of heat application, and even the style, quality and position of the fuse holder all make a big difference to the actual thermodynamics of the item !!
The other thing folks forget is a 13 amp fuse is designed to CARRY 13 amps .. not fail at 13 amps .. it should fail at 13+ a tad .. but they all have "leeway" depending on how well they are made.
If fuses were as good as some folk think they are then electrical items would never catch fire ... but they do, with regular, and dangerous, monotony

I thought this was about the bombing of Stanley airports runway in the Falklands for a second, disappointing to be honest ::)

I thought that the DTM fella had started wearing a cape! :P ;D

Superfuse! Now where's that Victor tanker?

A wealthy close friend is a sucker for this type of marketing, and will not buy anything unless he has paid top whack for it.

But a fuse is there to protect the cable not the appliance, although when a fuse does blow due to a fault in the appliance it can save both. Although, yes, often appliances can still catch fire and burn your house down! ::) ::)

Indeed, was rather a close shave

There is no specific rupture rating for a 13A domestic fuse over time, in fact it will potentially carry about 40A for 100 seconds (based on the operating graphs) :y
What everyone forgets is the fuse is NOT to protect the device, it is to protect the supply.
If the device is pulling current to the point it takes out a fuse, its already got an issue, the fuse clears the fault from the supply (the same is true of circuit breakers etc) :y
Also, the key cause of fires is loose screws an poor contacts adding resistance to the circuit and getting hot (I2R) whilst pulling far less than the rated operating current

I knew as I have already said it is protection for the cable :D ;)

And also the internal earth connections and bond wires of a class 1 electrical product (which relies on an earth connection to protect against electric shock); anything supplied with a BS1363 plug has to be tested at 25A down the earth conductor for a minimum of 100 seconds without catching fire or otherwise becoming dangerous to give the fuse enough time to disconnect the fault.
