Automatically resetting circuit protector

A circuit protector comprising an input terminal and an output terminal, a reed switch having two elements connected between said input terminal and said output terminal, a first coil connected between said input terminal and one of said elements;

• a second coil connected to said output terminal;
• said second coil causing the closing of said elements as a function of voltage at said output terminal;
• and magnetic bias means located in proximity to said switch for maintaining said elements in a closed position until the occurrence of a predetermined condition said first and second coils causing said contacts to open as the current at said load increases.

A circuit protector comprising:

• an electromechanical switching device, a primary coil connected in series with said switching device, first and second resistors connected across said switching device and said primary coil;
• a secondary coil connected at a junction of said two resistors for generating a flux as a function of a condition of a load;
• whereby said switching device 4 is open when there is no power supplied and closed when the load reaches a predetermined percentage of its full level.
