The DIN VDE is legally anchored. Look at the laws.

    [*]Low Voltage Connection Ordinance § 13
    [*]Energy Industry Act § 49

We could choose whether we wanted the fire protection switches or not.

We now also have €3200 that *poof* get added on top.... and I’m not even condemning the circuit breakers. I just can’t explain where these high costs are supposed to come from.

As far as I understand, the fire protection breakers are often installed in combination with an "FI". These then control the FI when they switch. Now Schwörerhaus tells us "yes, we have up to 27 circuits, that’s where it comes from"...... but wait a minute..... we don’t have 27 FIs in the distribution box but 27 normal fuses. These are usually secured in blocks by an FI and you end up with about 5 to 7 FIs for a single-family house.
At about €100 per fire protection breaker (the price range is between €80-130), I definitely don’t get to €3200.

I am currently in a conversation with an employee of Schwörerhaus. Either I have completely wrong ideas or later I will stand in front of our finished distribution box and feel somehow cheated because there are only 7 of them inside: namely one per FI :-/

EDIT: Are there maybe homeowners here who have already installed these things? A photo of the distribution box would be worth its weight in gold, just to get an idea of how it is really done.

After a colleague brought up the topic yesterday, as it was new to me until now, I have gathered that this fire protection switch in the single-family home sector is only required for wooden houses, timber frame construction, etc., in other words, everything that is easily flammable.

That means for my brick solid house without [WDVS], this switch is not necessarily required! Correct?

The switches are not per RCD, but per fuse/circuit.
Those things cost around 100 euros + installation each. A larger fuse box is also needed.

The VDE applies to wooden houses / timber frame houses.
VDE is a standard, not a law.
We built without residual current devices. We just had to sign that the electrician informed us about the standard. There were no problems with the power supplier either.

The switches are supposed to trip if you manage the trick of drilling into a power line so strongly that the switch trips, but only lightly enough that the fuse does not blow.

The standard is to be reviewed again to see if it is necessary at all.

We also had these switches removed, despite the timber frame construction.... It was not a big issue.
