    Abstract: A manual opening mechanism for use with an isolation switch of a circuit interrupter is fully integrated into the circuit interrupter. The manual opening mechanism includes a rotating handle that is accessible from the front panel of the circuit interrupter. Rotating the handle applies force to the centerline of the isolation switch drive shaft, which prevents uneven loading and thus optimizes robustness during manual opening of the isolation switch. In addition, the handle has an ergonomic design, and is proportioned to minimize the force that an operator must apply to the handle in order to open the isolation switch.

    Abstract: An art fault mitigator includes a sensor structured to detect at least one of a user within vicinity of the power system protection device, a light within the power system protection device and an overcurrent within the power system protection device; a mechanical switching device including a fast mechanical circuit interrupter and an actuator; a power electronics circuit coupled to the mechanical switching device in parallel and including a current commutator structured to commutate current from the fast mechanical circuit interrupter to the power electronics circuit upon turning OFF of the fast mechanical circuit interrupter, a power electronic circuit interrupter structured to allow the current to ride there-through up to a threshold current, and a current limiter structured to limit the current flowing through the power electronics circuit interrupter; and a controller including a trip control structured to control operations of the mechanical switching device and the power electronics circuit.

    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.
