Circuit breakers are the "final control elements" of the electric power industry, akin to control valves in the process industries. They are strictly on/off devices, used to make and break connections under load in power systems. Circuit breakers automatically open when dangerous circuit conditions are detected.
Yes, a circuit breaker can reset itself under certain circumstances. A circuit breaker is a safety device that is designed to protect electrical circuits from overloading and causing potential fires or damage. When an overload occurs, the circuit breaker will automatically trip and cut off the flow of electricity to prevent any harm.

The working rules of automatic reclosing are equally simple: when a fault is detected, the circuit breaker trips. The controller then waits for a predetermined time before closing the circuit breaker again. If everything is normal, this is the end of the whole process, but if the fault persists, the circuit breaker trips again.
The automatic circuit breaker is also known as the automatic switch and is a type of electrical remote control switch. It combines the switch (see Electrical switchgear) and the overcurrent protective device.During a short circuit or overload, the automatic circuit breaker trips but is ready for operation again, unlike other fuses.
