All North American utility suppliers are set up for 60 Hz. As such, all breakers are designed for 60 Hz operation.
Although European electricity is 50 Hz, North American breakers would no doubt function well.
It is highly recommended that you employ the services of a qualified electrician for installation or modification of any electrical service.
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
I am assuming by your description that the panel is protected by a 90 amp breaker and the breakers in the panel when added up is 200. This is okay as long as your 90 amp breaker trips on a regular basis. It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
200. Although you cannot exceed current ratings on any branch circuit without tripping that circuit. You need to make sure that you do not exceed 160 continuous load amps to meet NEC requirements of not overloading a breaker to more than 80% under continuous load.
The number of amps cannot be determined from just the energy in joules. To calculate the current in amps, you would need to know the voltage of the circuit as well. Amps is equal to power (in watts) divided by voltage.
A 200 amp circuit breaker can support a maximum electrical load capacity of 200 amps.
200 amps
The maximum amperage capacity of a Siemens breaker rated at 200 amps is 200 amps.
The necessary specifications for a 200 amp panel with a main breaker include a capacity to handle 200 amps of electrical current, appropriate voltage rating, sufficient number of circuit spaces, and compatibility with the electrical system in the building.
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
Check the nameplate on the service panel. There it will tell you what the buss capacity is. On a 200 amp service nothing in the wiring configuration is allowed to be less than that the service rating. In the market there are 200 amp 42 circuit distribution panels.
A 200 amp main breaker can support a maximum electrical load capacity of 200 amps.

1200 Amps is a huge breaker. Typical houses might have between 100 and 200 Amp service. Since this would have to be a very unique installation you would have to provide a lot more information before cost could be computed. You also have to indicate who is supplying the breaker which would be a significant cost on its own.
Connect the circuit to the appropriate size circuit breaker to meet the required amperage of the circuit. Turn the breaker on and use the circuit. Unless the circuit is of a very high ampacity, plus 200 amps, don't worry about voltage drop over 50 feet.
