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.
The purpose of a circuit breaker is to open an overloaded circuit. Its function is to prevent overheating. As current moves through a circuit, the voltage can vary.
Fuses and breakers are used to interrupt excessive current flows known as faults.
The list of permitted responses somehow got lost from your question. But from
the description, I'm guessing that a "fuse" or "circuit breaker" is implied.
A thermostat.
to prevent a circuit from overloading if too much current flow safely interrupt the circuit if it becomes overloaded
Option 1: Use a circuit breaker. The breaker is essentially a switch that will turn off the electricity in the event of a current overload fault occurring somewhere either in appliances connected to the circuit or to the circuit's own wiring. Option 2: Use a fuse. Will turn off the electricity in the event of a current overload. One downside is that fuses destroy themselves in order to cut-off the power, so you have to replace them. Another downside is that some of the simpler types of fuse are not as fast-acting as a circuit breaker so they can allow more damage to occur before they shut off the supply of current.In reality, unlike a circuit breaker, a fuse is not really an "overload protection device" but a "device for opening a circuit which has a higher current subjected to it than it was designed to carry", such as a short circuit condition.For example certain types of electric motor need to draw a high start-up current so a circuit feeding such a motor must be fused at up to 250% of the motor's rated running current or Full Load Amperage (FLA). So a motor could be in an overload state up to 200% over its FLA and still not blow the fuse.

A fuse is a device used to keep electrical circuits from overheating is not a true statement. A fuse is used to protect the wire of the circuit from an over current being applied to the circuit. This over current could be caused by a couple of scenarios. Two non insulated conductors touching one another and creating a short circuit. Another cause could be an non insulated conductor touching adjacent grounded equipment. Whatever the cause the fuse will isolate the fault instantaneously.

If a fuse in your home keeps blowing it can be caused by several things. Most often it is because that circuit is being overloaded. There is simply too many things pulling power on that circuit. It can also be caused by a short in the wiring somewhere. Can also be an appliance is defective. Can also be someone has installed a fuse that is too small for the circuit. Whatever you do, do not install a larger fuse than the circuit calls for to prevent it from blowing. The fuse is there to protect the wiring from overheating and catching on fire.
To prevent an overload or short from causing the wiring in the circuit supplying power to the appliance from overheating and possibly catching on fire. The fuse is there to protect the wiring and not what is plugged into that circuit.
To prevent overheating/damage/fire of the electrical components in a circuit.
If an engine overheats the metal parts expand and the engine will seize up. A seized engine is usually unrepairable.
