A circuit breaker system having an electrical contact system, the electrical contact system includes one or more electrical contacts that are movable between a closed and an open position via a rechargeable spring loaded operating mechanism. An air motor recharging system includes an air motor operably coupled to the operating mechanism for recharging a closing spring. The air motor recharging system further comprises a solenoid valve that, when in an open position, supplies pressurized air to the air motor from a pressurized air storage tank at a preferred operating pressure sufficient to enable the air motor to drive a charging shaft and gear assembly to recharge a closing spring. The circuit breaker system further comprises an air compressor to delivers compressed air to the air storage tank to fill and maintain the storage tank at a preferred storage pressure.
