[0002] Circuit breakers are categorized by their scope of use into high-voltage and low-voltage circuit breakers. Low-voltage circuit breakers, also known as automatic switches or "air switches," also refer to low-voltage circuit breakers.

They are used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. They automatically disconnect circuits in the event of severe overloads, short circuits, or undervoltage faults. Their functionality is equivalent to a combination of a fuse-type switch and an over- and under-temperature relay. Furthermore, interrupting the fault current generally requires no component changes, making them widely used.
