A resettable internal actuating mechanism, used in an electronic sectionalizer having a tube assembly movable between a closed position and an open position, includes a latching element of an electro-mechanical component mounted in the tube assembly and biased to move to an extended position and movable to a retracted position in response to receipt of an electrical signal, an actuating member spaced from the latching element and mounted in the tube assembly and being biased to move from a non- actuated position to an actuated position, and a linking lever mounted in the tube assembly between the latching element and the actuating member and biased to pivotably move from a latched position to an unlatched position. The linking lever has opposite ends latched respectively to the latching element and actuating member when the linking lever is at the latched position and the latching element is at the extended position to thereby hold the actuating member at the non-actuated position. The opposite ends of the linking lever unlatches respectively from the latching element and from the actuating member in response to the latching element being moved to the retracted position to thereby release the linking lever to move to the unlatched position and the actuating member to move to the actuated position. By moving from the non-actuated to the actuated position, the actuating member extends outwardly from the bottom end of the tube assembly and moves an external latching mechanism of the electronic sectionalizer from a locking position to a releasing position to cause movement of the tube assembly from the closed to the open position.
