Circuit Breaker

A circuit breaker is an automatic electrical switch that is designed to protect an electrical circuit from damage caused by overcurrent or short circuits. Circuit breakers are commonly used in residential, commercial, and industrial electrical systems, and they are an important safety device that helps prevent electrical fires, equipment damage, and personal injury.

Circuit breakers work by monitoring the amount of current flowing through an electrical circuit. If the current exceeds a preset level, the circuit breaker will trip, or open the circuit, to prevent damage to the electrical system. When the circuit breaker trips, it interrupts the flow of current, which stops the electrical current from flowing and prevents further damage.

Circuit breakers are available in a variety of types and sizes, and they can be classified based on their voltage rating, current rating, and interrupting capacity. Some common types of circuit breakers include thermal circuit breakers, magnetic circuit breakers, and hybrid circuit breakers.

In addition to protecting electrical systems from overcurrent and short circuits, circuit breakers also help improve the reliability and efficiency of electrical systems. They can also be used to switch electrical circuits on and off, which can be helpful in certain applications.
