Abstract

A circuit breaker includes a vacuum interrupter having a closed position and an open position. The circuit breaker includes a linkage operatively coupled to and extending from the vacuum interrupter and a high-speed actuator operatively connected to the linkage. The high-speed actuator is operable to move the linkage by a repulsion force and cause the vacuum interrupter to move to the open position. The circuit breaker includes a decelerator with an integrated latch assembly operatively coupled to the high-speed actuator. The decelerator decelerates the repulsion force of the high-speed actuator and latches the actuator with the integrated latch assembly to maintain the vacuum interrupter in the open position.
