7A fuses, thoughts? UPDATE, It gets better...

[CAWORK]

I saw these a few days back in a mobile repair/hardware shop (Generally a good shop), but could anyone give an explanation on these?

The standard BS1362 fuse is length 25.4mm (1 inch), diameter 6.3mm (1/4 inch). So these are not for domestic plugs it would seem, at 5 x 25 mm but what is the question? We use fuses in many appliances, 5 x 20 is more normal, and 6.3 x 32 seems to be next size, I have often wondered why 3.15 amp is so popular?

I don't know what would use 5 x 25 mm, did you ask what they were for?

Open one up and see if there is any sand in side, if there isn't then they are not compliant with safety requirements. And therefore probably illegal to sell in the UK.

The sand is necessary to quench an arc that will be created when the fuse blows. If the fuse wire melts and the arc is not quenched then the fuse will continue to pass current ( through the plasma of the arc ).

5x25 mm fuses for 5 x 25mm fuseholders -- often panel mount on electrical and electronic equipment back in the day. Occasionally inside on skeleton fuseholders.
Even on terminal rails in industrial process kit? https://catalog.weidmueller.com/catalog/Start.do?localeId=en&ObjectID=group786893920929
Not a commonly used size any more.

3.15A? - I googled and its Renard's fault https://www.sizes.com/numbers/preferred_numbers.htm

The packaging suggests they were not intended for the UK market.

...and in itself, there's nothing wrong with having 7A plug fuses - we hold a stock of 1, 2, 3, 5, 7, 10 and 13A fuses.

Good Afternoon

I didn't ask what they were for (Saying that the shop owners/workers English is quite poor) and I didn't actually buy any (The photos I've posted were taken within the shop).

If I remember rightly, I think they might have been next to all the other 'Normal' (Well, normal looking.....) plug fuses.

My best guess would be that someone ordered the wrong thing, and either didn't realise, or decided they would try to sell them anyway.

I don't know what would use 5 x 25 mm, did you ask what they were for?

I've come across lots of that size in various appliances.

I've been back to the shop today (But didn't buy/ask anything) and look what else I've found, 13 Amp BS1362 fuses...(No, the 'Scan for more' thing doesn't work).

Also (Although I'm not a spark) I thought multi gang switches (I.E. two or more switches on the same plateswitch) were always 2 way?

 

[plugwash]

BS1362 fuses are 0.25 inch by 1 inch, the "6mm" could be explained by rounding but "30mm" is far too long for a BS1362 fuse.

I looked up the address on the sticker, it seems to be a rather run down industrial unit. Better than a mailbox shop I guess.

At best it seems like a housewares importer who are in over their head when sourcing electrical items. At worst............

I've never seen a single-peice multi-gang non-dimmer switch from a reputable supplier in the UK that wasn't two way. Though some manufactuers do make 1 way switches in their modular ranges.

 

[flameport]

That switch is the same as the hopeless MK Essentials range which has mysteriously disappeared, minus the MK logo.
Total crap.

 

[CAWORK]

Cheers, (As a person who has watched your YouTube videos) I thought it looked familiar.

I was looking for a two way smart switch, no reason why a battery powered smart switch can't be two way, however the TC-link range only seem to be simple on/off, and the Energenie needs a special second switch understandable as does not use neutral or batteries, yes there are wireless buttons which can work as two way switches, but can't simply swap one of a pair of two way neutral less switches to a two way.

The intermediate switches have always been rare as three gang, even mechanical, but yes BS 1362 can't be 6 x 30, either one or the other, wonder if the shops buyer has any idea that they are wrong?

With a MCB you can test them, although I have only ever done it once, but not really anything we can do but trust the writing on a fuse.

Given it's all of dubious quality I'm wondering if those BS1362 are up to snuff, remember reading of counterfeit ones that were of poor construction and weren't sand filled either:

Counterfeit BS1362 Fuses

Randomly purchased 4 packs of BS1362 fuses - 3 are confirmed as counterfeit! Video of a counterfeit fuse in an explosive short circuit.
