A circuit breaker is an electrical protection device that is designed to automatically interrupt the flow of electric current in an electrical circuit in the event of an excessive current, such as an overload or a short circuit. They work by detecting the excessive current and then interrupting the flow of electric current by breaking the circuit. Circuit breakers help prevent electrical faults and reduce the risk of fire.
Circuit breakers are recognized as critical units in aircraft electrical systems. In an aircraft, circuit breakers are usually located in the electrical panel, most commonly located in the cockpit or avionics bay. They are designed to be easily accessible by the pilot in case of emergency, allowing the pilot to manually trip the breaker and disconnect the electrical system if necessary.
