Low-voltage circuit breakers, also known as automatic switches in the past, are essential electrical components designed to safely control and protect electrical circuits. These devices can handle normal load currents, overload conditions, and even short-circuit currents, making them a crucial part of any electrical system. In addition to their switching function, they provide various protective features such as overcurrent, short-circuit, undervoltage, and leakage protection. This makes them highly versatile for different applications. There are several types of low-voltage circuit breakers available, categorized based on their use, adjustability of protective settings (selective vs. non-selective), and the type of arc-quenching medium used—such as air or vacuum. In most domestic applications, air-type circuit breakers are commonly used due to their reliability and cost-effectiveness. These circuit breakers come in a wide range of capacities, starting from as low as 4A up to as high as 5000A, allowing them to be used in both small residential systems and large industrial environments. They are widely employed in low-voltage power distribution systems, controlling power supply lines at different levels, as well as in the operation and protection of various mechanical equipment and electrical terminals. Their flexibility, safety, and efficiency make them an indispensable component in modern electrical infrastructure.
