Midwest Hearth Motor Run Capacitor Single MFD Dual Voltage 370/440 Volts (Oval, 4 MFD)
based on 0 ratings
Run capacitors are used on permanent split capacitor motors (PSC), such as blower motors, condenser fan motors, and compressors. Their purpose is twofold: to increase the starting torque of the motor; and to bring the current and voltage of the motor back into phase, which increases the motor's power factor. The latter is not as important on residential equipment as it is for commercial or industrial equipment where large numbers of motors are used. The run capacitor is built for continuous operation and remains in the circuit after a motor starts.
