ABSTRACT:
A drawout switchgear apparatus is characterized by a cell having a front opening through which a circuit breaker is movable on tracks into and out of the cell for engagement and disengagement with electrical terminals within the cell. A cell frame includes formed columns at outside corners members, cross-strut members, and formed horizontal members which members are of similar cross-section of a substantially U-shape with U-legs and a bight and with a laterally extending flange. Each member converges to form junction corners where they are fastened together. A track extension and interlock cooperate to facilitate removal and retention of the unit into and out of the cell.
