DRAWOUT TYPE CIRCUIT INTERRUPTER WITH INTERLOCKED LEVERING MECHANISM |
摘要 |
<p>An enclosed circuit interrupter includes a removable drawout unit mounted within an enclosure and sealed by an enclosure door. The drawout unit is movable between a connected position and a disconnected position by a levering mechanism operated by a levering crank. A shutter prevents insertion of the levering crank unless the circuit interrupter is tripped by actuation of a trip plate. An interlock prevents removal of the inserted levering crank when the drawout unit is at any position intermediate the completely connected and completely disconnected positions. Closing of the enclosure door is prevented when the levering crank is inserted.</p> |
