A fuse breaks a circuit if the load on it is greater that what it is rated for and it burns out then has to be replaced, but only after the cause of the overload has been found and repaired first.
A circuit braker on the other hand, does in fact work the same way as a fuse does, but it works more like a switch that cuts off if the electric current going through is greater than what the breaker is rated for. Unless there is something mechanically wrong with it, or it burns out, it does not have to be replaced, but will continue to kick out or, "brake" the circuit until what ever is causing the overload is fixed.
Fuses and breakers comes in all sizes and shapes and may not be recognized, times for what they are.

What are fuses and circuit breakers What are they for?
A fuse is a device that contain a thin strip of metal that will melt if there is too much current through it.A circuit breaker is a reusable safety switch that breaks the circuit when the current gets too high.They are used to prevent circuits from overheating.
What is vacuum interrupter?
Vacuum interrupters are special types of high-voltage circuit breakers.
Where are both parallel and series circuits used?
there are both used in some electronics eg circuit breakers,ring main unit,circuit board.
Which of th following is the best description of an electrical energy type source?
Machinery and equipment that relate to or are poerated by electricty, two examples and circuit breakers
Why do fuses protect us?
Fuses have a maximum amount of energy that can pass through them, if there is a sudden excess of energy, they break and the circuit stops. Thus preventing any further damage to our household appliances etc..
Circuit breakers are used for the same purposes as?
fuses
What are the circuitrotectors?
Circuit protectors are fuses and circuit breakers.
Which of these are alternatives to fuses?
circuit breakers
Does a 1977 Harley fl have fuses?
No fuses, but it does have circuit breakers.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
Are easier to use than?
circuit breakers ...fuses
What fuses and circuit breakers provide protection in the event of?
Short circuit fault.
How do fuses or circuit breakers help protect homes?
During an electrical fault, be it a short circuit or circuit overload, fuses and breakers are designed to open at a specific amperage. This opening of either device eliminates a fire hazard before it gets a chance to start. This is how fuses and breakers protect the home.
When did circuit breakers replace fuses in homes?
1950's
What are the main protective devices in a power system?
Circuit Breakers or fuses.
What protects circuits and their components?
Fuses, fuseable links and circuit breakers.
What protects against circuit failure?
Two examples of how to protect against circuit failure are fuses and circuit breakers.
