Abstract: The present invention discloses a data transmission apparatus of a circuit breaker controller. The data transmission apparatus comprises: a first component having a first power supply and a second component having a second power supply. The first component and the second component share a storage device. The second component is connected to a main circuit of the circuit breaker controller. The second component collects parameters of the main circuit and stores the parameters in the storage device. The second power supply powers the second component and is powered by the main circuit. The first component is connected to a communication device. The first component establishes data transmission between the communication device and the storage device. The first power supply powers the first component and is powered by an external power supply. The second power supply is connected to the first power supply and transmits a control signal to the first power supply.

Abstract: A self-test module of an electronic circuit breaker includes a power supply assembly with a rechargeable battery, a self-test enablement assembly, an induced power supply assembly, a boost power supply, and a micro control unit (MCU). The self-test enablement assembly is connected to the rechargeable battery and includes an enablement button, a capacitor and a first power chip connected in series. The induced power supply assembly includes a buck chip. The boost power supply includes a second power chip and a boost chip connected in series. The MCU includes a plurality of pins that are connected to the first and second power chips, the buck chip, and the boost chip. The self-test module has two working modes; the electronic circuit breaker may be provided with or without a load current. The MCU operates the self-test procedure, indicates the self-test status, and maintains the indication for a period of time.
