Can anyone help with my Spanish elec tarif ?

Bit of a long shot this chaps, and its not urgent but one of those nagging things, and I'd like your help please.

Our electricity sometimes trips because we are trying to use more power than our main fuse allows.
As I understand it, this main fuse is spec'd based on the tarrif you are on.

The electricity bill is here next to me and details from that are

Tarifa: 2.0.2
Potencia contratada: 3.3 kW

Photos of the fusebox and a close up of the main fuse are below
Can someone tell me if we have the correct fuse for the tarif we are paying for and how you work it out, because I can't tell.

Your help would be very much appreciated.

Thanks guys, I wasn't expecting to hear there are fuses outside. So now it all makes a bit more sense.
I'm out there in 3 weeks so I'll have a look, let you know what I find.

Thankfully, although the house is old, we gutted it a couple of years and had all the electrics replaced. I can't speak for the feed into the house but the rest of it is all good.
