They stop electrical applications like washing machines from harming us if they malfunction.
Suppose something goes wrong and the live wire gets connected to the casing. You are now at risk from a fatal electric shock but the fuse stops this. Because the earthing wire is connected to the case and it offers little resistance energy surges down it. This overloads the fuse which melts thus breaking the circuit and protecting you.
Additional Answer
It should be noted that a fuse or circuit breaker is designed to protect a circuit against an over current. It is not designed to protect people!
Circut Breaker
you can use a fuse or circuit breaker
There are two main devices. One is the circuit breaker. It provides a dual function where in it can detect short circuits with its internal magnetic sensor and overloads with its internal bi metallic strip. The other device is a fuse. It operates by melting a fusible link, that breaks the fault current that is in the circuit, when a high current rush through the fuse.
to protect the source from overloading a switch can be opened as a circuit breaker, fuse, overload protection schemes
Electrical discrimination is when a smaller circuit breaker (fuse) located closer to an electrical fault, operates before a bigger circuit breaker which is further away from the fault. This then stops disruption to other circuits by knocking out the fuse which not only knocks out the fault, but all the other circuits with no faults on them.

A circuit breaker can trip due to overloading, short circuits, or ground faults.
A circuit breaker can trip due to overloading, short circuits, or ground faults. To prevent tripping, avoid overloading circuits, regularly check for faulty wiring, and use surge protectors.
A circuit breaker may keep tripping due to overloading, short circuits, or faulty wiring.
Common reasons for a circuit breaker disconnecting frequently include overloading the circuit, short circuits, ground faults, and old or faulty wiring.
The circuit breaker immediately trips when the power is turned on to protect the electrical system from overloading or short circuits, which can cause damage or fires.
Common causes of a circuit breaker tripping include overloaded circuits, short circuits, and ground faults. To prevent tripping, avoid overloading circuits, use surge protectors, and address any electrical issues promptly.
A breaker can trip in a circuit due to overloading, short circuits, or ground faults. To prevent this, ensure the circuit is not overloaded, use the correct size breaker, and regularly inspect and maintain the electrical system.
A circuit breaker may trip randomly due to overloading, short circuits, or faulty wiring. These issues can cause the circuit breaker to sense an abnormal flow of electricity and shut off to prevent damage or fire.
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.
A range circuit breaker is designed to protect electrical circuits from overloading and short circuits. It functions by automatically cutting off the flow of electricity when it detects an abnormal increase in current, preventing damage to the circuit and reducing the risk of fire or electrical hazards.
Factors that contribute to the tripping of a circuit breaker include overloading the circuit, short circuits, and ground faults. When the electrical current exceeds the safe limit or encounters a fault, the circuit breaker automatically trips to prevent damage or fire hazards.
