Help me understand, please

Why is A2 of the switch in the middle (E321) connected to L3 instead of neutral? Shouldn't it be neutral???
I think the switch is supposed to switch depending on whether there is 230V across A1 and A2. And the timer on the far right (E124) is supposed to accomplish this, the moment it receives "the signal" from my energy provider over mains electricity.
EDIT: Maybe A2 is not connected to L3. But it's NOT neutral either. There is:
0V between A2 and L3.
230V between A2 and neutral.
400V between A2 and L1.
400V between A2 and L2.
Oh it being a fuse makes sense, although the way it is wired makes even less sense, then. The middle device (the 'contacter'?) is not used by any load at the moment. But I wanted to start using it again.
Bottom view:
Don't mind the loose wire. It's french wiring. It's not even connected at other end.
Global view:
I have two boilers that are now both connected to the same switch (and this is time dependent somehow). This switch is shown left. The black wires are from boiler 1, and the blue and beige wires are from boiler 2. The orange pair are neither input nor the load, so they must be 'commanding' the switch operation.
I want to start using the middle contacter for boiler 2 so that each boiler has its own switch.
The bottom of the fuse (so far right) is connected to A1 of contacter (so thing in middle) (via gray cable) as well as to A2 of switch (far left in global pic) (via orange cable).
I'm not sure whether to call it a switch or contacter again.
There is 230V between A1 and neutral (at the moment. This may change, depending on the time of day.)
That floating circuit breaker really ties the whole setup together lol. Do yourself a favour and clean this mess up before trying to reuse this old disused crap again.
But frankly it's more beautiful this way
The charred remains of your burned down house will look really cute lol
