Circuit interrupter with over-temperature protection function for power cord

A circuit interrupter device comprising:

• input terminals adapted for connecting to a power source;
• a cord having multiple current-carrying wires including a phase wire and a neutral wire for carrying a current from the power source at an input end to a load at an output end, and further having a detection signal conductor wire extending between the input end and the output end;
• a temperature controlled module having at least one temperature controlled switch adapted to be disposed on a device under measurement which is associated with the load, the temperature controlled switch being coupled between the detection signal conductor wire and either the phase wire or the neutral wire of the current-carrying wires at the output end of the cord, the temperature controlled switch changing its connection state based on a detected temperature of the device under measurement;
• a reset switch coupled between input ends of the current-carrying wires and the input terminals for electrically connecting or disconnecting the current carrying wires and the input terminals;
• and
• a switching control circuit for controlling the opening and closing of the reset switch, the switching control circuit being connected to the detection signal conductor wire at the input end of the cord, the switching control circuit controlling the reset switch to disconnect the current-carrying wires from the input terminals based on the open or closed stated of the temperature controlled switch.
