that is actually completely irrelevant

What exactly is this variant used for? Do you then have a remote control and can switch (several) push buttons from a distance?

By the way, NP stands for "Nicht Potentialfrei"

Potential-free means that you can work with two different voltages on the input side and the output side.
With non-potential-free, input voltage = output voltage (in this case 230V).

Potential-free outputs are often used for inputs of a PLC, DDC, etc., i.e. an application with a controller or control device behind it.
In your case, where you only want to switch a lamp on/off, it therefore does not matter...

The difference is that one is a zero-crossing switch and the other is not.

A zero-crossing switch is suitable for switching resistive loads without causing power line disturbances, such as popping noises. For switching inductive loads like coils or transformers, zero-crossing switches, or zero-voltage switches, are less suitable because a high inrush current is generated.

which radio actuator do I need if I want to operate several LED spots on a 230V line? I want to dim them and switch them via radio.

also the Eltako FD62NP-230V. You have to set the operating mode to "phase-cut." Provided you use EnOcean pushbuttons
