two eletronics with one circuit breaker
The electric oven is a high-power appliance and should have it's own outlet that has its own breaker.  I don't know anything about the electric code in Brazil, but it may even require this.

If you want other low-power outlets nearby, you can group a few on a single modest breaker.  That gives better overall protection, since the trip current for the small appliances will be less than it would be otherwise.  It also isolates better the voltage sag and other issues caused by the high power appliance.
