Abstract
A miniature circuit breaker, a control method thereof, and a control system thereof, where the miniature circuit breaker includes a circuit breaker body and a current detection unit. The circuit breaker body and the current detection unit are located in respectively independent cavities in the circuit breaker and are electrically coupled to each other. After a current that flows from one end of the circuit breaker body flows through the current detection unit, the current flows into another end of the circuit breaker body. The current detection unit includes a voltage drop detection assembly and a signal output terminal. The voltage drop detection assembly includes a first voltage sampling point and a second voltage sampling point, where the first voltage sampling point and the second voltage sampling point are coupled to the signal output terminal.
