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

I go to the warehouse, wander around the warehouse and point my finger at what and how much I take.

I order while sitting and drinking coffee and wait for the materials themselves to be brought from the warehouse to the car Sometimes they bring me to the construction site when something bigger.
Recently they brought a Profile + 2060 wardrobe for 1000 - it weighed about 100 kg 8-O

It does not change the fact that no one has ABB.

And I have ABB in abundance The clamps are still decent Overall, I think they are solidly constructed. In the legrand, I also broke the bolt, and the plastic at the bolt broke again, or the plastic from the rail fastening ... This Legrand is terribly fragile

EATON, Legrand and of course LC, Kanie reign supreme in Mazowieckie. There is also Eti - mainly in Castorama.

Schracka is also difficult to access.

Hello.
DOEPKE accessories are recommended.
There are no problems with it.

best regards

Hello

Can anyone say something about Vynckier's circuit breakers or RCDs? I have never had anything to do with them, but I once dug up a B10 switch from this company and a 2-pole RCD at home, but I do not remember how it is.

Some of my observations.
Most manufacturers have several product series. Legrand and Schneider have recently introduced less expensive series for typical residential applications.
These are the so-called Developers.
Recently, I have installed Bemko on several blocks. I twisted a few screws a fact. I was left with a four-pole main switch, which I installed due to the lack of lacquer at home. Surprisingly, Bemko is the same camp as Eaton. From the same production line. The other cameras are Eaton. Unfortunately, after a few short circuits, the B 10 sockets stick together - to be replaced.
I used to edit Kania, Zext, etc.
Differential kite for complaints after a few months. When tightening, the S-rings diverge. Massacre.
I have been in the profession for 20 years. And in fact, the most breakdowns are with cameras with the highest percentage on the market. I have replaced damaged cameras of each brand.!
I respect the brands they produce for the maritime market. These are products that meet stringent standards.
The most commonly used manufacturers are ABB, Schneider.

I trusted Hager and I have the entire switchgear in Hager's devices together with the FW2 4x36 switchgear. The second producer is Eaton. This is the end. The rest does not exist. This is my "whim". I check the RCD once every six months, sometimes once a year. Nothing falls asleep or breaks down.

what do you think about Etimat? on the Allegro below PLN 4

There is not a single Polish company? Such with Polish capital and a factory?

For my part, I do not recommend Shrack - the differentials fall off after a few months, they turn off for no reason, and then it does not pass the measurements.
I will say cool with Schneider - own phase rails are a minus fact, but at least it's a nice system with end caps and it looks good.
Legrand is good if not a development series.
Eaton - great, no operational problems.
Hager - see above.

And I recommend it because nothing has fallen in the last 2 years and everything is checked without problems. Golden question, what series? Basic or Amparo?

I think Hager is the most decent option. I have been using hager for 10 years and I had only 2 complaints. I usually assume everything from switchgear to security. and everything is fine. And it's not expensive.

New secondary circuits in power plants and stations "stand" mainly on Hager / EATON, there are no problems, and PSE or distributors in such facilities have quite a lot of requirements.

I agree, there is no problem with this attachment and very practical and solid assembly. I recently replaced the security. in a single-family house, previously there were ETIs, they did not even stick well on the rail.

I just bought circuit breakers and 3 HAGER cdc240j differentials because several people here recommended this company and I immediately noticed a big problem with differentials. In order to start them, you need to use very high force that makes your finger hurt. Sometimes the thumb slips and then it hurts even more and the differential is still not attached. The second or third time it turns on. I wonder if this is a factory defect (all 3 pieces work like this) or is this type of type because this is the first time I encounter something like this? Installations will sometimes be operated by a woman with long nails, who is afraid to use force, especially on this type of equipment, and it's hard for me to imagine it. With overcurrent switches also from Hager, there is no problem at all, they are turned on very gently and you do not need to use any force.

I have over 20 RCDs and RCBOs from Hager in the switchboard. No problems. Shifting the lever up and its resistance is a rather subjective feeling. Besides, what kind of RCD are we talking about 2-pole or 4-pole? I have such and such. Certainly no manufacturing defect. You just need to use more force - you don't come to the point until it snaps into place, you just let go (for lack of strength?) Probably halfway or 3/4 of the lever's way and it bounces back.

I just checked Hager's 4p RCD and Eaton's 2p RCD, because I have it on my desk. Wajcha walks hard here and here, so everything is fine. This is normal.

These are 2 Field RCDs. You just have to use so much force that at some point I have to let go because the finger hurts like hell or slips off the lever. For comparison, I have some older RCD 2 pole Legrand and RCBO also 2 pole Moeller and in them the levers are much easier. The difference is really big.

I don't know what to write. The situation is a bit funny. How do you deal with the switch disconnector? Maybe you don't have it at all? This is where the resistance to lifting the lever is there.

Maybe some ... peasant needs to be hired?

And you checked the disconnector from them, it should be "even heavier"

Soon I am picking up the segment from the developer, when I had the opportunity to enter the building (I agreed on measurements for the kitchen), I noticed the ideal brand security in the switch cabinet. Have any of you ever encountered this before? What are your opinions on this?

Oh, a typical developer at the lowest possible cost and probably the company itself is the smallest problem here
