What is an electrical circuit breaker

An electrical circuit breaker is a device that, in the event of overload, disconnects the electrical circuit to protect it from damage. Under certain circumstances, it can also protect electrical devices and also protect people and animals. The circuit breaker is basically a substitute for a little bit of insurance policy. Unlike fuses, the circuit breaker will not be destroyed in case of overloading and there is no need to replace it. Therefore, only new circuit breakers are used in new buildings and the fuses work in older buildings with a non-modernized electrical installation.
