The circuit breaker is equipment for controlling the on-off of a circuit, and can automatically cut off a power supply when the circuit is abnormal, so that the safety of the circuit and the equipment is protected. A feeder terminal is a device for connecting a feeder to a device, which functions to transmit a power signal and to monitor and protect a circuit. The feeder terminal can monitor parameters such as voltage, current, temperature and the like in the circuit, and when the circuit is abnormal, the feeder terminal can cut off a power supply in time to protect the safety of the circuit and equipment. A control cable is a cable for transmitting control signals, and is generally used to connect a control device and a controlled device, such as a circuit breaker and a motor. In the power system, a circuit breaker, a feeder terminal and a control cable are mutually matched to jointly realize protection and control of a circuit. When the circuit is abnormal, the feeder terminal can monitor abnormal signals and transmit the signals to the circuit breaker, and the circuit breaker judges the state of the circuit according to the signals, so that corresponding actions are taken to protect the safety of the circuit and equipment. Meanwhile, the control cable can transmit control signals to the controlled equipment to realize control and adjustment of the controlled equipment.
