Carrier P291-3554RS Dual Run Capacitor 35/5 Mfd 440V

The Carrier P291-3554RS is a dual run capacitor refers to a cylindrical electrical component used in most of the HVAC equipment. It is used like a miniature battery to store electrical charge for the purpose of enhancing motor operation. Motors that are in operation for the first time need a boost of electrical power to overcome the stalling forces. The capacitor affords this additional voltage, thus making it easy for the motor to start without putting a lot of strain on the electrical circuit. The said capacitor remains energized after being charged, thus supporting the consistent output voltage for continued proper running of the motor.
