Abstract
A power circuit interrupter includes a housing having an opening, one or more vacuum interrupters including separable contacts, and an operating mechanism, supported by the housing, adapted to open and close the contacts. A linear actuator cooperates with the operating mechanism to open and close the contacts, and is responsive to a close signal to close the contacts. A pivotable trip member protrudes through the opening of the housing and cooperates with the operating mechanism and the linear actuator to open the contacts when pivoted from a first position to a second position. A close circuit includes an input inputting the close signal. A micro-switch includes an operator and a contact electrically connected in series with the input of the close circuit. The operator is engaged by the pivotable trip member to open the contact in response to partial pivoting thereof from the first position toward the second position.
