Abstract:
A circuit breaker racking system includes an electrical drive operatively connected to a mechanical racking mechanism that carries the circuit breaker and moves the circuit breaker between a connect position and a disconnect position within a cubicle, and a circuit breaker trip unit that receives remote commands and controls the electrical drive based on the remote commands. A switchgear system including at least one circuit breaker with an integrated auto-racking system is also provided.
