Abstract
A switchgear system may include a switchgear frame and a truck carrying a circuit breaker and supported for linear movement on the switchgear frame. A drive mechanism may rack in the truck and the circuit breaker is in electrical connection with primary circuit contacts, and may rack out the truck and the circuit breaker is electrically disconnected from the primary circuit contacts. As the drive mechanism racks in the circuit breaker, a shutter linkage moves a shutter opened, and as the drive mechanism racks out the circuit breaker, the shutter linkage moves the shutter closed over the primary circuit contacts.
