What is a trip switch in physics?

A trip unit is the part of a circuit breaker that opens the circuit in the event of a thermal overload, short circuit or ground fault. An open circuit will not conduct electricity because either air, or some other insulator has stopped or broken the flow of current in the loop. How do I test a trip switch?

Top 5 Reasons Your Circuit Breaker Keeps Tripping and How to …

If an electrical overload or short occurs, a breaker will "trip", effectively cutting off power to the affected circuit. This interruption in electrical flow stops excessive current that can cause overheating, which if left unchecked, could result in electrical fires. By acting as a safeguard, circuit breakers help to preserve both your electrical system and your physical safety
