The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard.
For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps.
The short answer is to keep you safe.

What is the function of the fuse or circuit breaker in a circuit?
A circuit breaker/fuse is designed to protect the wiring from getting overloaded.
Will a circuit breaker function properly if it is back fed?
Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.
What is the function of a circuit breaker in a cu al breaker panel?
A circuit breaker in a circuit breaker panel is designed to protect the electrical system from overloads and short circuits by automatically shutting off the flow of electricity when it detects a problem.
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
What causes a circuit breaker to go bad?
A circuit breaker can go bad due to factors such as overload, short circuit, age, or mechanical wear and tear. These issues can cause the circuit breaker to trip frequently or fail to function properly.
What is function of vcb?
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
What is the function of a 15 amp circuit breaker?
To trip when current is in excess of 15 amps and protect the circuit components.
What are the function of consumer box?
what is a circuit breaker / fuse current rate value for lamp and fan load circuit
The Function Of A Twenty Amp Breaker?
It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.
What is the function of the breaker for an electric range?
The function of the breaker for an electric range is to protect the appliance and the electrical circuit from overloading or short circuits by interrupting the flow of electricity when there is a problem.
Will a circuit breaker function the same if supply and loads are reversed?
Yes, a circuit breaker will function the same if supply and loads are reversed. This is the way that some sub panels are fed instead of a main disconnect at the top of the distribution panel.
How the circuit breaker differ in its function from combination switch fuse unit?
The function is the same in that they both are designed to remove an over current situation by opening the circuit. A tripped breaker can just be reset. A blown fuse needs to be replaced.
