The miniature circuit breaker is also quite useful. A circuit breaker primary function is to automatically shut an electrical circuit off when it receives too much current. Simply put, it serves as a guardian who keeps an eye on and controls the flow of energy inside a circuit. The circuit breaker quickly shuts the electrical flow when it detects an excessive spike in current, avoiding possible risks including electrical fires and equipment damage. Functions of a Circuit Breaker The principles of electromagnetism and thermal-magnetic tripping govern how circuit breakers work. An electromagnet and a bimetallic strip are two crucial parts that are located inside the breaker. The electromagnet and the bimetallic strip cooperate to keep the circuit closed under typical working circumstances, enabling current to flow freely. The current, however, is more than the breaker's rated capacity when there is an overload or short circuit in the circuit. The high current at this location causes the bimetallic strip to heat up quickly, bend, and engage the tripping mechanism. The electromagnet detects the irregular current concurrently and produces a magnetic field that helps trip the vacuum circuit breaker open. Circuit Breaker Types Circuit breakers that use heat: These are frequently employed in domestic and light business settings. These breakers' bimetallic strips react to the heat from an excessive current by tripping the circuit. Industrial settings often have magnetic circuit breakers, which employ an electromagnet to detect a rapid rise in current and trip the circuit.
