Breakers limit the current on the conductor to a safe level, too many appliances plugged in. You trip a breaker, hopefully you then transfer load to another circuit. Breakers use two different methods to accomplish this, one uses a bimetallic strip and the current passes directly through, too high a current causes the strip to deflect. It acts on a mechanism much like the sear in a guns trigger, the deflection pulls the trigger causing a spring to open the contacts and turn off the circuit. Another type is thermal magnetic, current passing through the breaker causes a magnetic field to act on a coil tripping the breaker. When breakers are wired and work properly they prevent fires!
Bending metal opens a switch
They can avert electrical fires in case of fuse boxes and many modern circuit breakers can stop people from being seriously electrocuted
If that pathway is to ground, it is called a short circuit. It should blow fuses or circuit breakers but can cause fires if protective devices are not functioning right.

a breaker or a fuses
because wires can get really hot and start a fire
Fuses and Circuit Breakers act as a control mechanism to the flow of current in electrical circuits. A fault can develop in an electrical appliance without us noticing and this is where circuit breakers and fuses help in automatically disconnecting the faulty appliance from the power source. Most electrical faults resulting excess heat generation which in turn cause fires. Electrical shock can also be prevented by special types f circuit breakers called Earth Leakage Circuit breakers (ELCB). These breakers operate whenever there is an earth leakage protecting humans.

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.
Circuit breaker or a fuse
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.
In most places fuzes have now been replaced by circuit breakers. They prevent circuits from becoming overloaded and starting fires. With modern circuit breakers, you just have to flip the switch to turn the electricity back on. Old fuses were like the base of a light bulb, and a filiment would burn out if it was overloaded. Back then, you had to replace a blown fuze with a new one to restore electricity.
