The invention discloses a circuit breaker action behavior analysis device based on thermal effect and electrical characteristic quantity, comprising a sensor assembly, a signal collection module, anda behavior analysis module. The sensor assembly comprises a current sensor and a temperature sensor, wherein the current sensor is nested in a circuit breaker trip coil, the temperature sensor is attached to the surface of the circuit breaker trip coil, and the current sensor and the temperature sensor output signals by using a serial port. The signal collection module is configured to acquire signals collected by the current sensor and the temperature sensor, and the state of the protection and auxiliary contacts of the circuit breaker. The behavior analysis module is configured to analyze the tripping behavior and make intelligent judgments by using the expert knowledge base of circuit breaker tripping. According to the circuit breaker action behavior analysis device based on thermal effect and electrical charac
