An overload alarm device is provided. The device is disposed in an electric auxiliary system for avoiding overload of the system. The device includes a current detection unit, a voltage comparison unit and an alarm unit. The current detection unit includes a non-contact sensor connected to the circuit of the system for sensing the current of the system so as to output a voltage signal corresponding to the current. The voltage comparison unit compares the value of the voltage signal with a preset value. As the value of the voltage signal exceeds the preset value, the voltage comparison unit drives the alarm unit to generate an alarm signal.
