Aqualisa Digital Quartz - Electrical Connection

But the instructions to use 3 amp as if it is to protect the appliance when 13 amp would do.

No it wouldn't. The manufacturer has considered the I²t of a 3A fuse and has designed his product to withstand that energy. He has no need to design his product to withstand more than is considered in his installation instructions.

Are you saying they deliberately manufacture inferior/weaker products especially for Britain?

 

[stillp]

No. What protection do they specify for other countries?

 

[EFLImpudence]

Eu não sei - but as winston keeps saying, Europe doesn't have fused plugs nor FCUs so they will be on a 10A or 16A circuit.

Rubbish. The product is designed to work in all EU countries.

Rubbish. The product is designed to work in all EU countries.

Does anyone know what the instructions say when these products are sold in other (non-UK) EU countries?

Here's an Electrolux cooker hood:

Edit - That is from Brazil if it makes a difference.

The product is designed to work in all EU countries.

Is it? Does it achieve the same standard of safety and dependability in all those countries?

Thanks - as expected, not a fuse in sight. The multilingual titles on the front page seem to imply that it's a multilingual document. If so, what do the English instructions say?

Kind Regards, John

Particularly given the thermal fuses which seem to exist in the motors of at least the more reputable of these products (which nevertheless call for a 3A FCU in the UK), I suspect that there have probably been extremely few, if any, safety-related 'incidents' with these extractor fans in any country. It therefore could well be that the answer to your question is essentially 'Yes' - i.e. that the products "achieve the same standard of safety (i.e. near-zero 'incidents')" in all countries.

Ah, interesting.

I can't see a mention of a fuse but -

so, similar unnecessary requirements for UK.

Indeed, but that same requirement for an 'all-pole' isolator in the fixed wiring seems to be translated identically into all the other languages, e.g. ...

Además del interruptor mostrado en el plano de instalación/diagrama, debe haber un interruptor omnipolar en el cableado fijo con una abertura entre contactos de 3mm como mínimo. 3-pole ('omnipolar')

En plus de l’interrupteur indiqué sur les schémas de raccordement, l’installation électrique fixe doit intégrer un interrupteur omnipolar ayant une ouverture entre contacts d’au moins 3 mm.

Die Ventilatoren der Serie Decor verfügen über die Schultzklasse II (doppelte elektrische Isolierung) weshalb es nicht notwendig ist, die Geräte zu erden. Bei der Installation ist ein Trennschalter (siehe Anschlussbild) miteiner Trennstrecke von mind. 3 mm pro Pol vorzusehen (allpoliger Schutz).​

... so the same ('unnecessary') requirement in all countries - although, unusually, seemingly no requirement for 'fusing down' in any country.

Oh. didn't see that. Unfortunately seem to have found one that may not demand a fuse.

That's a partial answer, with which I agree, but what about the dependability? We don't know the repeated breaking capacity of the thermal fuse (if resettable).
