The reason for a fuse to break the current within a circuit is to protect the circuit itself and prevent fire. When an excess of electricity (or, too much electricity for the circuit to safely handle) attempts to pass through the fuse, a physical break within the connections of the fuse occurs. By breaking the connection, the excessive electricity is stopped, and prevented from causing possible overheating within the circuit, which could result in fire and permanent damage to the circuit.
Protection. They shut off the power to protect the equipment circuits, the main circuits and people.
It must understand that, short circuit is the case when the electricity find a lower resistance path to travel through. It will result to large amount of electricity flow and with high current flow then it emitted heat and would be so hot that it start the fire. Preventing short circuit damage, it install the fuse or circuit breaker as the bottle neck. When too much of the current flow through then the circuit breaker stop the flow of current and prevent fire.
Fuses & circuit breakers.
A closed path through which a current can flow is called a circuit. Electric Circuit:)
It is a fuse or a breaker. The wire inside the fuse will burn out and will need to be replaced once the fault has be corrected. A breaker is designed to click open, so breaking the circuit.
Fuses have absolutely no effect whatsoever on the voltage applied to a circuit. Fuses are simply overcurrent protection devices, intended to disconnect the circuit in the event of a sustained overload current or a short-circuit fault current.
A fuse can break the current flowing in a circuit only once whilst a switch can break the current flowing in a circuit many times. In other words a switch can switch the current on and off - and then on again and off again - indefinitely but a fuse can only switch off the current once.
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
circuit breaker and fuses used in series to break the circuit in overcurrent situation to block current to flow through circuit.
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.
Both fuses and circuit breakers cut off a circuit from its power supply when the total current through the circuit exceeds the current rating of the fuse or circuit breaker, usually due to a short to ground or overloading of the circuit. Both use materials that respond to heat.
Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.A circuit breaker or fuse.
Electrical circuits, to limit the maximum current flow. Fuses will "blow", or burn out, and cause an open circuit, to stop the flow of current when it could potentially damage a circuit, system, or device.
Fuses blow when there is a short circuit or an over current condition.
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
fuses or circuit breakers
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
