A current limiter includes a circuit device including a power supply transformation circuit to transform a power supply, a detection circuit to detect and transform a load current of a load into an output voltage, a control circuit to interrupt a connection between the power supply and the load according to the output voltage, a reset switch circuit to connect the power supply with the load, and a protection circuit including a warning element. Thus, when the power of the load exceeds a predetermined value, the current limiter will shut the power supply automatically to turn off the load to prevent the load from being worn out due to an excessive load current and to turn on the warning element to inform a user of the overload of the load.
