1. A switchgear system, comprising:
a switchgear frame including an interior compartment and primary circuit contacts;
a drive mechanism mounted on the switchgear frame;
a truck carrying a circuit breaker and supported for linear movement on the switchgear frame, the truck separate from and movably connected to the drive mechanism, the drive mechanism configured to rack in the truck where the circuit breaker is in electrical connection with the primary circuit contacts, and rack out the truck where the circuit breaker is electrically disconnected from the primary circuit contacts; and
a shutter mechanism operatively connected to said drive mechanism, the shutter mechanism comprising a shutter and a shutter linkage connected to said drive mechanism and the shutter, wherein as the drive mechanism racks in the circuit breaker, the shutter linkage moves the shutter opened, and as the drive mechanism racks out the circuit breaker, the shutter linkage moves the shutter closed over the primary circuit contacts,
wherein the driving mechanism moves the shutter mechanism while the driving mechanism simultaneously moves the truck.
