A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.
The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.

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.
The difference between 16A TP and 16A TPN isolator is the type of the circuit breaker that is used. The terminal design is the other difference.
I think that the questioner is asking what is the difference between an isolator and a circuit breaker.A circuit breaker is a switching device designed to interrupt a fault current.An isolator is not intended to break a live circuit but, rather, to provide a visible separation between a circuit component and live conductors.For example, isolators (or 'disconnectors' in US parlance) are located on either side of a high-voltage circuit breaker. If the circuit breaker requires maintenance, then the procedure is to:a. trip the circuit breaker.b. open the isolators on each side of the circuit breaker, so there is a visible gap between the circuit breaker and the 'hot' conductors.c. apply temporary earths (grounds) between each isolator and the circuit breaker.d. complete a 'permit to work' card.e. begin work.
A non-auto circuit breaker is a circuit breaker with the trip element removed. Basically, it is a modified circuit breaker that is now a disconnect switch (glorified disconnect switch).

A dryer does not require a quick disconnect breaker. However, it is recommended to have a dedicated circuit with a proper circuit breaker for the dryer to ensure safe operation and to meet building code requirements.

The breaker is hot because it is designed to trip and disconnect the electrical circuit when there is an overload or short circuit, causing it to generate heat as it operates.
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.

VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
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.
run in a electrical system means a wiring & conduit runs coming from Panel Board Circuit Breaker to its branch circuit loads in a circuit. while circuit is a designated number of branch breaker in a panel board where power load was individual connected.
Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
A disconnect breaker is used to interrupt the flow of electricity in an electrical circuit for safety or maintenance purposes. It functions by opening the circuit when activated, effectively cutting off the power supply to the circuit. This helps prevent electrical hazards and allows for safe work on the circuit without the risk of electric shock.
