The CYM10 type current adjustable miniature circuit breaker has a micro residual current circuit breaker with adjustable leakage action current grading, including a current transformer and a gear switch with three moving contacts, a leakage action current grading adjustable circuit with a first resistor, a second resistor, and a third resistor. The first resistor, the second resistor, and the third resistor are connected in series in sequence. One end of the first resistor is connected to one output terminal of the current transformer, the other end of the first resistor is connected to one end of the second resistor, the other end of the second resistor is connected to one end of the third resistor, and the other end of the third resistor corresponds to the third moving contact of the gear switch. The first contact of the first resistor and the second resistor corresponds to the first moving contact of the gear switch. The second contact of the second resistor and the third resistor corresponds to the second moving contact of the gear switch, The static contact of the gear switch is connected to the other output terminal of the current transformer. By converting the gear switch's moving contact, the leakage current value of the miniature residual current circuit breaker can be adjusted in real-time to adapt to different electrical environments.

Adjust the current according to the user's power consumption to ensure electrical safety; According to the user's electricity consumption needs, it is not necessary to replace circuit breakers that do not match the current
