The rating is 48kW. It means that if you put a load of 200 amps across that 240 volts line the power safely through that box is 48000 watts = 48 kiloWatts (because Watts is voltage multiplied by current). You can put any load on there up to that max.
None of those kilowatts come from the box itself - that is just its capacity to deliver from the electric company.

kilowats don't exist until you use them.
there are only as many kilowats as you use. If you run an appliance that uses 1kw per hour then you just used 1 kw.
KW is a measure of power.
the formula for power is:
P =I * V
I=current=200amp
V=voltage=240V
therefore that box is capable of outputing 200*240=48000W so that is 48KW.
I believe that's measured per hour.
Think of Power like you think of a gas tank in a car. The power is "available". It's sitting there. You only measure what is used. Your engine running at max idle can't use fuel faster than it can come through the fuel line. If your engine uses fuel faster than it can come through the line, you're asking for problems (mainly increased fuel pressure in the line can cause the line to bust open.) 48KWH means you can use that much power in one hour without risking burning down the place by causing the power lines to get hot (power lines get hot if you try to pull more current through them than they can handle normally).

200 amps at 240 volts would be 48kw.

The panel can safely supply 48 kW of power, but in practice, in a normal home, you would generally use less than 1/10th of that at any given time.

multiply 200 x 240 and get 48KVA, if it is all resistive / heating type of load it is 48KW
Kw is a unit of real electric load, kva is reactive load.

240*200=48000 (watts)
=48 (KW)

as many as you want....its a form of measurement for current used
