circuit breaker question
(OP)
A device says it need and electrical utility and a circuit breaker of 10 A. Now, it have a circuit breaker of 20 A. Is 20 A OK or it is wrong?
What is the function of the circuit breaker ?

You should not be making these decisions if you need a simple question like this answered.

That said, the comment that the breaker is there to protect the wires is the slightly more correct of the two, but it just is not that simple. Typically, a machine or device will have been designed with a specific type of circuit protection requirement, and to attempt to interpret someone else's engineering decisions is a minefield of potential dangers. We cannot know, nor can you, nor can anyone else who thinks they know just from a brief description. Only the engineer who said "use a 10A circuit breaker" can be expected to know if another value is possible. To guess is to risk fire and harm. So bottom line, the only safe response is, do not interpret of change what was said unless you are willing to accept PERSONAL responsibility for all possible outcomes.

@jumacao, lay down your predicate. Size of wire deriving power from breaker, loads being supplied by those lines, etc. . , etc. . etc.
Then we can talk sensibly.

So tell us,are your querying the device itself (as you appear to be), or the branch circuit that supplies the device.
RE: circuit breaker question
Arguing that the breaker can be 20A instead of 10A because the machine has it's own protection is not a valid arguement if the machine in fact does not have it's own protection.
I would expect the machine does not have it's own protection since the machine documents specified a 10A breaker.
You still need to use a 10A breaker given the information you have provided. You haven't given any info that would indicate otherwise.
