A fuse contains a component that melts or breaks in some other fashion when excessive current flows through it. This breaks the electrical circuit. A fuse that has functioned in this way can never be reused.
A circuit breaker is a mechanical switch that opens, breaking the flow of electricity when the current goes above a set point. A circuit breaker can be reused by simply closing the switch again once the problem causing excessive current has been taken care of.
What else can I help you with?
What are the circuitrotectors?
Circuit protectors are fuses and circuit breakers.
Which of these are alternatives to fuses?
circuit breakers

Are easier to use than?
circuit breakers ...fuses
Circuit breakers are used for the same purposes as?

What has replaced fuses in the main fuse box in a house?
Circuit breakers have replaced fuses in many modern homes. Circuit breakers offer better protection against overloads and short circuits, and they can be reset rather than needing to be replaced like 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.
Is there any alternative for fuse in house wiring system?
Yes, circuit breakers are a popular alternative to fuses in house wiring systems. Circuit breakers are reusable and can be reset after they trip, unlike fuses which need to be replaced. circuit breakers can help protect against overload and short circuits in the electrical system.
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.
What are the main protective devices in a power system?
Circuit Breakers or fuses.
