Abstract: A circuit breaker and a power supply system. The circuit breaker is disposed between a direct current power source and a load, the circuit breaker includes a first coil, a second coil, a switch unit, and a driver, where the switch unit and the driver form a linkage connection. The direct current power source is coupled to a first end of the first coil and a first end of the second coil, both a second end of the first coil and a second end of the second coil are coupled to one end of the switch unit, and the other end of the switch unit is coupled to the load. Inductive reactance of the first coil is less than inductive reactance of the second coil.
