Protections, miniature circuit breakers which companies to avoid and which to us

I found a similar thread: https://www.elektroda.pl/rtvforum/topic1204169.html#12663955, summarizing the statements from him: Legrand some recommend, but quite a lot of negative opinions, and recommended: EATON, GE, Hager, Moeller / Schrack, Schneider. A familiar young electrician advised against Legrand, recommended EATON.

It is, of course many other new companies and brands so I am asking for information:
- what to take, because they are certain, even expensive
- which not to take because they are emergency, you replace: burned, melted, blocked buttons
- which are reasonably good and cheap

While browsing the websites and allegro, I found the following brands:

expensive, above PLN 10	medium below PLN 10	below PLN 6.6
ETIMAT10 B25A G61 B25A	AEG B25A NOARK B25A TRACON C25A	ADELID B25A APAR ELECTRIC B25A CNC C25A YCB2 MCB C25A SEZ B25A XBS MCB 1P C25A ZEXT C25A	try it yourself
ETI B25A 10kA	KANLUX B25A LEGRAND 1P 6kA RX3 C25A SCHNEIDER C60N B 1P 25A	BEMKO C25A LC B25A LC TEC B25A	advised against
ABB C25A GE HAGER B25A Schrack B25A	EATON MOELLER B25A	CHINT B25A	zalecane

Will you say this when the button is blocked and you will not be able to turn on the electricity?

Hello. I have been using Hager and ABB for several years. Legrand muck (test button in RCD does not work) And in Eaton Test button does not reflect. I can write so much.

This theorizing will get you nowhere. The network contains statistics of studies conducted under comparable conditions, conducted by relevant research institutes. You have to look for, not create fanciful theories.

For now, we do not know how this test button is supposed to reflect. So the same as above, a groundless opinion, without any value

Test results ... will test one piece in one environment.
Electricians repair breakdowns and see what they need to exchange more often about this type of information / opinions.
Thanks to @Magic_moon, I would like more such opinions, also for those cheap brands.

Buddy ... if you don't know some things then you'd better stay silent.

Legrand's protections were No. 1 but a few years ago, while Moeller and eaton are one company. In my opinion, all these switches are of sufficient quality, only important to maintain appropriate working and assembly conditions. I know from experience that in the case of switchgear assembly, after most construction works are completed, they can last for years, but are very sensitive to dust.

I think it's not about the TEST button.
RCD probably fell asleep. If you do turn off-turn on with the lever, TEST will start working.
He'll wake up.

For such texts - good bad equipment- you can pay dearly in the pool forum.
It spoils the company's reputation.
These are tests without justification. Because single failures are not a measure of the quality of the equipment.

I recommend Hager and Chint.
Out of 58 prefabs in 2015, no Chint hardware cabinet was annotated with a defect.
For 123 prefabricated items with Hager I have one cabinet written off after replacing the contactors.

From the news, he sleeps until the first launch hehe :)

Chint and Bemko are Chinese, but they are good Chinese. (So they say)

Bemko is "good Chinese", I haven't heard a bigger joke for a long time. Bemko o kanlux is the biggest crap on the market.

In my career, I have replaced three Legrand rcd units. After switching off, all of them did not get up anymore. In my house, after five years, two S301 B16s fell for unknown reasons, and one S303 B20 after a few fans by the builders. I would like to add that I had a problem with Legrand in places where I connected the strobe at parties, after a few flashes it went off. In three places I exchanged for Eaton and after the problem. I have been using Eaton Moeller for several years and so far I have not had any breakdowns.

My picks on them anyway.

On no :

Legrand it's nice - and that's all. The circuit breaker mechanisms fail after a larger short circuit. RCDs are even worse, they are terribly sensitive to dust and dirt. The test buttons do not work regularly. Notoriously after measurements, RCDs cannot be turned on. They are a bane for surveyors.

ETI - the same as in Legrand, plus grinding and strange noises when activating the lever, plastic descriptive covers falling off.

Schneider - went down to the dogs, shot himself in the knee using specific rails instead of universal combs. I take a wide berth.

Bemka, LC, sewers, kites and shitting , I do not take in hand at all. How much did I exchange for this in new development switchboards. They fall like flies, threads break, casings break, mechanisms hang.

Chinti - I do not use it, but I had the opportunity to replace a few broken RCDs. The very name repels me, because it is immediately associated with China :D

On Yes :

As I wrote in another topic EATON and only EATON . Zero complaints and strange operational damage.
It is also recommendable SCHRACK and Hager , I do not use them, but I have never encountered any problems during operation.

Like a colleague above, I can advise against the LC brand. A few fuses after disconnecting the power on my own did not turn on at all and I had to replace it.

I usually use EATON. What annoys me about legrandes is that the rail can only be mounted on one side.

PS I noticed what some of the overcurrent circuit breakers say and write fuses. After all, this is a mistake and is repeated on our forum regularly.

What does it mean to disconnect yourself because I do not understand?

I have 3 EATON differentials, I'm happy, but in one of them the TEST button is sometimes pressed after pressing it, and you have to tap the housing to make it pop out. Someone above also noticed similar symptoms. The advantage is the solid fastening of the cable - I tightened as much as I had and the screws were durable. Overall I recommend it.

Hello. Most of them are EATON, sometimes Hager, I skip others.

Mostly ELTON

And what is that?

When I was still working in the trade, the best were GE, Hager and Moeller (now Eaton) - FAEL (now Legrand) - it was also complaint-free. The customers of Kanlux, etc. brought the most shit and breakdowns. For 3 years, GE returned several times out of the thousands sold as complaints, because of the connection screws - the threads were failing. Moeller never came back, and neither did Hager. Legrand broke down over time and the differences have already appeared in the complaints.

In my case, most of the equipment is assembled by Hager, ABB and Schneider. I certainly do not recommend LC Tec equipment. They do not stick to the mounting rails.

@ malina998 can you respond to @ Łukasz-O's statement:
"Schneider - went down to the dogs, shot himself in the knee by using specific splice rails instead of universal combs. I avoid a wide arc."

Hello
I use Eaton, Hager, Legrand, Chint.

I didn't have any events in Hager (I consider this brand as a premium class). I, the client, want to pay for a higher-quality product, and I suggest it to him. Eaton is ok for me too, although I had two or three instances where the RCD exploded (phase-to-phase short circuit). Well, it's for a very large number of installed ones. I also think Legrand is ok, although as for the RCD, my comments coincide with what Łukasz-O wrote, in addition, I met with "sleeping" (in the first attempt they do not pass in the measurements, only after "waking up" they behave correctly), about which I even wrote here on the forum at one time.
In my opinion, chint is the weakest in terms of quality, although I had no problems with it (opinion based on the experience of others). And there is also ETI, with which I also had no incidents. Chint and ETI did not install much.

I once bought (more than 8 years ago) very cheap GE circuit breakers. Sometimes they had a problem with the contact in the on position. But then probably someone introduced the "left" series of these Sek. Or it was some kind of counterfeit.

Added:
I have a similar opinion as kol retrofood (posts # 5 and # 7, which I haven't read before). Anyway, any equipment, regardless of the company, can break down. And the main factor causing the failure rate is general negligence on the construction site. How many times do you see, unprotected, dust-covered switchgears.

Yes. These specific / strange busbars are a failure I use very little rails themselves ... But personally, I haven't had any unpleasant incidents with Schneider. Colleagues with longer experience must have installed / replaced a lot of security features and their opinion is more reliable.

I usually work on Schneider and ABB. In the first one, I had contact with a factory-damaged contactor (with closed contacts it had no transition) and the RCD did not respond to the TEST button. ABB equipment was not a problem and I have not yet replaced it due to damage.

Regarding ABB, I don't know why, but in my area ABB modular equipment has been virtually unheard of for at least 10 years. There is no wholesaler or relatively new switchgear.
I haven't installed it for a long time, but from what I remember, they had exceptionally good connection clamps compared to the then reigning Fael, where tightening the bolt more tightly ended with breaking the clamp together with the plastic.
ABB's mechanisms also seemed to be more robust.

I don't buy online, but I know they're available. I am surprised that ABB is not available in electrical wholesalers in my area.

I also do not buy online.
I go to the warehouse, wander around the warehouse and point my finger at what and how much I take.
