Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.
An alternative to using a fuse is to use an electrical circuit breaker.
You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.

You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
A Murray or similar breaker would work but most inspectors want the brand breaker to match the brand panel.
Electric circuit need a main circuit breaker that can protect the whole circuit from short circuit even in ground fault. It's safer if you use breaker with built in ground protection.
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
you can use a fuse or circuit breaker
