Ultra-fast moving conductor with removable core pin

A circuit interrupter comprising:

• a line side structured to electrically connect to a power source;
• a load side structured to electrically connect to a load;
• a stationary conductor comprising a stationary separable contact;
• a moving conductor, the moving conductor comprising:
• a moving separable contact;
• a hollow outer stem comprising an interior cavity;
• and
• an operating core inserted into the outer stem and structured to be used when the circuit interrupter is put into operation to regulate power flow between the power source and the load;
• an operating mechanism structured to actuate the moving conductor in order to open and close the stationary and movable separable contacts;
• and
• an electronic trip unit structured to actuate the operating mechanism,
• wherein the stationary and moving separable contacts are electrically connected between the line side and the load side,
• wherein the operating core is structured to be removed from the outer stem, and
• wherein the operating core is structured to fill the entirety of the interior cavity.

A method of producing a movable conductor for use with a circuit interrupter, the method comprising:

• producing, from copper, a hollow outer stem comprising an interior cavity;
• producing a work hardened aluminum core structured to be inserted into the outer stem so as to fill the entirety of the interior cavity and structured to be removed from the outer stem;
• and
• inserting the aluminum core into the outer stem prior to putting the circuit interrupter into operation to regulate power flow between a power source and a load.
