I had and ID yesterday not trip on test.
Ordering a new one on Amazon this morning, I see a price difference between Legrand [30mA,2P, Type A, 25A, ), TX3, RX3 and DX3 - what are the technical differences? Any to be wary of safety wise?
Google’s French AI cousin says:
Ces termes désignent différentes gammes de matériel électrique de la marque **Legrand**.Ils correspondent à des niveaux de performance et d’utilisation distincts pour vos interrupteurs et disjoncteurs différentiels :
-
RX³ (RX-cube 3) : Gamme économique et essentielle réservée à un usage domestique de base. Elle offre les fonctions de sécurité primordiales sans fioritures (standard).
-
TX³ (TX-cube 3) : Gamme de milieu de gamme très courante, idéale pour les chantiers résidentiels et le petit tertiaire. Elle offre une meilleure modularité (démontage individuel sans enlever le peigne) et une plus grande robustesse.
-
DX³ (DX-cube 3) : Gamme professionnelle et industrielle haut de gamme. Elle offre les plus hautes performances, de grands choix de calibres, et accepte de nombreux accessoires et auxiliaires (comme des blocs différentiels adaptables).
Pour vous orienter, le tableau suivant détaille le positionnement de ces gammes:
| Gamme | Usage principal | Caractéristiques clés |
|---|---|---|
| RX³ | Résidentiel de base | Sécurité essentielle, idéal pour une installation économique. |
| TX³ | Résidentiel & Petit Tertiaire | Confort d’installation, déconnexion facilitée, usage très courant. |
| DX³ | Tertiaire & Industrie | Haute performance, évolutif, large choix de calibres et accessoires. |
you can also ask Google’s French AI cousin to reply in english…
You are assuming that I want it to reply in English.
And you are assuming that @ykm71 is assuming that and isn’t simply just passing on useful information 
In which case starting the comment with something like “for those who would prefer the response in English” or some such might make that clearer 
That’s a tad pedantic (I know, as I’m a pedant too 
). I too saw it as being helpful.

I have been very unimpressed with the quality of Legrand products. Flimsy plastic and pretty badly designed IMHO.
As a result I tend to stick with Häger (€€€) and Schneider (€€) products - both of which - whilst sounding extremely German - are in fact French companies.
Just my €0,02…

I’ve found Legrand light switches in particular to be rubbish. The house we bought had all Legrand light switches and the contacts seem to sometimes audible arc when turning off. Probably bad design for contact separation. I’ve had to replace three of them. I usually go with Schneider.
We’ve got a Legrand switch that does that from time to time. I was a bit concerned at first before I decided ‘that’s just what it does’. The house is full of Legrand and there’s only the one that does that.
I agree though, there are better (and more expensive, understandably) switches etc.
That’s crazy. I hope that neither of you ever has a gas leak!
The consuel forced us to buy a socket and plug from Legrand since they are the only company in the world that makes a set of connectors for 3-phase electricity with childproofing. (We have an external electrical box with our circuit breakers in it on our property.)
It pained me to remove the high quality Mennekes socket and replace it with the very overpriced Legrand one…
The only gas around here is what comes from my bottom 
Also flammable! I suggest opening a window, and avoiding prolonged periods in a small room… especially one with a Legrand light switch!
