What is the difference between a low-voltage circuit breaker and a fuse?

The following is a detailed analysis!

Low voltage circuit breakers, also known as air switches or automatic switches, are equivalent to a combination of knife switches, fuses, thermal relays, overcurrent relays, and undervoltage relays. They are electrical devices that have both manual switching functions and can automatically provide protection against undervoltage, voltage loss, overload, and short circuits. They have more comprehensive protection functions, are easy to adjust, can continue to be used after tripping due to faults, but are more expensive than fuses
