Patent ID: 7196433

Claim:
A multi-output circuit device with preset power supply priority, comprising: first and second power supply terminals for receiving power from a power source; first and second conductors; first and second normally closed overload breaking switches; a first output interface for conveying electricity to a first load, the first overload breaking switch and first output interface being connected in series between the first and second conductors; a second output interface for conveying electricity to a second load, the second overload breaking switch and second output interface being connected in series between the first and second conductors; and connection means for connecting the first power supply terminal to the first conductor and for connecting the second power supply terminal to the second conductor, the connection means including overload actuation mechanism means for opening the first overload breaking switch if the current flowing between the first and second power supply terminals exceeds a first predetermined value and for opening the second overload breaking switch if the current flowing between the first and second power supply terminals exceeds a second predetermined; value, wherein the overload actuation mechanism means comprises first and second overload actuation mechanisms that form a logic circuit having priority to supply power, and the current that flows between the first and second power supply terminals also flows through each of the overload actuation mechanisms, and wherein each of the overload actuation mechanisms comprises an electromagnet.
