<p>Switchgear (120) which combines a visible disconnect switch (122) and a circuit breaker (34) or interrupter (34) capable of interrupting fault currents. The switchgear (120) includes a carriage (140) and a switch actuator (190) connected to the carriage (140) for moving the carriage (140) between a switch-closed position and a switch-open position. A circuit breaker module (20) includes circuit breaker contacts (36, 38), as well as first and second contactor terminals (48, 60). The circuit breaker module (20) provides selective electrical connection between the contactor terminals (48, 60) depending on the state of the circuit breaker contacts (36, 38). A fixed disconnect switch contact (132, 134, 136) is attached to or comprises one of the first and second contactor terminals (48, 60), and a movable disconnect switch contact (178, 180, 182) is mounted to the carriage (140) so as to move with the carriage (140). The fixed disconnect switch contact (132, 134, 136) and the movable disconnect switch contact (178, 180, 182) are positioned for selective engagement with each other as the carriage (140) moves to the switch-closed position.</p> |
