Hello,
Due to some problems with my Netatmo doorbell, I started researching a different transformer.
In my search I see that several brands sell two types of transformers.
1 transformer for occasional use (doorbell)
2 transformer for continuous use.
Since I have now placed my Netatmo doorbell, I am going from non-continuous use to continuous use of the transformer.
My transformer is of the “non-continuous” type.
As an example, I found the following brands:
Continuously use
Legrand 413095 (16VA 12V / 24V)
Hager ST320 (18VA 12V)
Grothe GT1973 (16VA / 24VA 8V / 12V)
Incidental use
Legrand 413093 (18VA 12V / 24V)
Hager ST305 (16VA 8V / 12V)
Grothe GT3139 (12VA 8V / 12V)
Now I come to the following questions:
What is the difference between these two types?
Can I expect problems if I use my transformer continuously for a long time?
Is it safe to constantly use a transformer that is not intended for that?
If there is no or minimal difference between the two, why are these brands selling these two types?
Does the above (the use of a non-permanenty transformer) explain inexplicable problems?

Good question, I'm interested in this also.
How do you normally recognize a transformer for continuous use or incidental use? As manufacturers don't always take this up in the description of the transformer.
I believe I'm currently using a transformer for incidental use (although not sure) and would like to know if this can cause problems in the long run.

Hello,
When a transformer is an "incidental use" one, there is a bell symbol on it.
I have checked this on three brands, Grothe, Hager and (of course) Legrand
