The difference between a fuse and a circuit breaker.

Basic difference.

The fuse has a small cable that passes through it and if it is in a too high current disturbance condition (the temperature is too high) then the cord breaks out so it breaks the circuit.

In circuit breakers like MCB there is a quiet metal peace inside them either elongated wizards or arches in fault conditions when there is too much current going through (heating up the metal strip) and also breaking the circuit by touching a different piece of metal which then disconnects the circuit.

The main difference I suppose is that the mcb (miniature circuit breaker) can be reset after they are traveling but the fuse should be replaced unless you put a nail between connections.

Another difference is that there are different types of mcb that can allow more inrush to flow at the beginning and not explore the circuit when it is stable.

You can also get rcbo’s the rcd and mcb in the same circuit breaker which gives the best protection in case where there is an earth fault it will just trip the wrong circuit instead of all the circuits which are on the same rcd.

Fuse self-destructs to stop the flow of electricity in an overloaded circuit by melting and creating air gaps. This melting is caused by overheating of the fusible connection. the exploding fuse must be replaced to restore power to the circuit.

Circuit breakers, unlike fuses, do not self-destruct to stop the flow of electricity in overloaded circuits. instead, it uses a thrower switch to introduce an air gap to the circuit (in series with it), stopping the current flow until someone resets the switch to its closed position – after the overload condition has been fixed in the circuit. a common mechanism for detecting overload conditions and opening the switch may be a thermally-activated bi-metal spring, a solenoid coil, or a combination of both. the device is in series with a protected circuit and will trigger a mechanical response (open the switch) if the current exceeds the threshold which is the current value of the circuit breaker.

They are the same. circuit breaker fuse. However, the fuse generally refers to a device containing a piece of wire that melts if the current becomes too high, either as a wire fuse in an ancient fuse or a cartridge fuse in a plug etc.

Circuit breakers are commonly referred to as mechanical circuit breakers (mcbs). this is a device containing electromagnets. when the current becomes too high, they cause the spring loaded mechanical switch to open, cut off the power. there is still a fuse shape.
