The breakers that feed individual circuits are in parallel with the main AC line feeding the panel.
There may be a disconnect switch (in a seperate panel) or a main breaker ( in the breaker panel) that is in series with the AC main that feeds the rest of the breakers in the panel which are in parallel.
The purpose of a main disconnect is to kill all the power at once. Individual branch circuits are rated at 10,15 or 20 amp service and are in series with the load they supply (such as lights or an appliance).
A question that needs to be asked is whether or not you understand the difference between a series circuit, and a parallel circuit. A simple battery, switch, and lamp circuit would illustrate this for you. Think about it, if the breakers were in series, then just one failure, or any wall switch would turn off the whole house. Time spent doing simple experiments, and thinking about what you ask, have questions about, or things you are not sure of would go to great lengths to answer those questions. You really need to learn how to read a schematic, as well as blue prints since these things could answer this question, as well as others to come.
Parallel to one another, of course. In serie, one would trip cutting power everywhere, what purpose would that serve? The idea of breaker is to isolate one circuit that has a short.
Of course, the breakers are in serie with the rest of the circuit (where electricity is used) they protect.
As you have supply coming into the board it is connected into your main circuit breaker from there it is wired in parallel to each circuit breaker for you sub ccts..and from each circuit breaker to your field devices it is connected parallel...

Each breaker is in parallel with the others.
This means that each circuit (each breaker feeds one circuit) comes off the main "bus" in the breaker panel and is independent of the other circuits.
If the breakers were wired in series, then if one breaker tripped, ALL the power would be disconnected.
