A fuse protects a circuit, equipment, or person by being the 'weakest link'. In case of too much current flowing, it opens, breaking the circuit and not allowing electricity to flow. This prevents a continual overcurrent, and associated heat and fire.
the fuse wire is always placed in the live wireof an electric circuit,at a point, where the current enters in the circuit.the fuse wire melts when a given circuit gets overloaded or short circuited or power flunctuation takes place.this stops the flow of the electric current and in turn prevents electric fire. the circuit can be re-established by rectifying the fault in it and then re-inserting fresh fuse wire.
The purpose of protecting a circuit with a fuse or breaker is to protect the conductor in the circuit. The protection is always sized to the amperage allowed on the circuit conductor. If the load faults and creates a larger than normal current flow on the circuit, the fuse will blow or the circuit breaker will trip. This disconnects the faulted load from the circuit. Once the faulted device is removed from the circuit, the circuit can be re energized by resetting the breaker or replacing the blown fuse with a new one.
A fuse protects electrical equipment by interrupting the flow of current to the equipment.
fuses and circuit breakers protect the wire. every wire gauge combined with insulation is designed to carry a specific load.
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.

Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
Cooper Bussmann is a brand name for a specific type of fuses. These fuses are used with circuit breakers to ensure that the circuit does not become overloaded, resulting the failure of the circuit.
For a home owner, yes they are.
Getting shocked! or equipment damage.. It protects wires and equipment when sized properly.
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.
Two examples of how to protect against circuit failure are fuses and circuit breakers.
Protection. They shut off the power to protect the equipment circuits, the main circuits and people.
Fuses and circuit breakers do not protect a person from electrocution. They are in the circuit to protect the feeder conductors from having over current applied to them. The only type of breaker that will protect you from getting a shock is a GFCI.The way that fuses and breakers stop household fires is by opening the fault current on the circuit before the fault temperature can rise high enough to ignite any surrounding combustible materials.
They protect the downstream components from spikes in the eletrical system.CommentFuses and circuit breakers do not protect against 'spikes', which are near-instantaneous voltage increases. Fuses and circuit breakers are overcurrent protection devices, which protect appliances against excessive current due to overloads or short circuits. CommentFuses and circuit breakers are used to protect the wire feeder that supplies the load. A load could be connected to a circuit that would cause an increase of amperage above what the wire is rated for. If this condition happens the fuse or circuit breaker will open the load from the supply service.
Circuit protectors are fuses and circuit breakers.
circuit breakers
No fuses, but it does have circuit breakers.
Fuses and circuit breakers protect the conductors that are connected to them from not letting the current going above the current rating that is given to individual size conductors.the main function is to quickly stop the power to continue threw the loop., and to protect ,equipment from damage and people from dying, that may be in contact to a shorted circuitCommentFuses and circuit breakers are overload protection devices, designed to protect loads (e.g. appliances) against overload or short-circuit currents. They are not designed to protect people.to over come the over load conditions.In simple terms the purpose of a fuse or circuit breaker is to protect the wiring from overheating and causing a fire. That is why it is so very important to match the fuse or breaker with the size wire in the circuit.Protect the circuit from over current. Fuses and breakers prevent excessive amounts of current to flow through the conductors in a circuit which causes heat to build up making for a fire hazard.A circuit breaker or fuse is a protective device that shuts off power when the current exceeds a preset limit. It is designed to protect the wiring, and thus prevent damage to the equipment and fire.
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.
because wires can get really hot and start a fire
