Power distribution panel connector having thermal management feature

An aircraft power distribution system, comprising:

• a power source;
• a load;
• and
• a power distribution panel receiving power from the power source and selectively providing power to the load, wherein the power source is connected to the power panel by a lug having a heat sink portion, the heat sink portion having at least one increased dimension relative to the remainder of the lug;
• wherein the lug includes at least one fin, the at least one increased dimension including an increased height provided by the at least one fin;
• and
• wherein the at least one fin includes first, second, and third vertical fins, the first and third vertical fins projecting upward from a main body portion of the lug, and the second vertical fin projecting downward.

A power distribution panel, comprising:

• a printed wire board;
• a contactor mounted to the printed wire board;
• a first bus bar between the contactor and a power source, wherein the first bus bar is connected to the power source by way of a lug having a heat sink portion, the heat sink portion having at least one increased dimension relative to the remainder of the lug;
• and
• a second bus bar between the contactor and a load, the contactor operable to selectively open and close an electrical connection between the first and second bus bars;
• wherein the at least one increased dimension includes an increased width, and wherein the lug has a first width at first and second ends, and a second width between the first and second ends, the second width greater than the first width.
