Capacitors - Single
Commonly used with furnace blower motors, a/c condenser motors, a/c compressors and refrigeration compressors.
Choose from two can styles; Oval and Round
Choose from 370 and 440VAC
Capacitors are rated by microfarads (uF) and voltage. It is desirable to replace a capacitor with an identically rated capacitor. Motors operate at maximum efficiency when using a specified capacitor size. However a plus or minus 10 % rule of thumb applies to the microfarad rating when changing out a capacitor. If necessary, the replacement capacitor voltage rating can be higher than specified, but not lower without effecting the capacitor life.
Always replace the run capacitor when installing a new motor. If a defective capacitor is in the circuit the motor will probably not run. If it does run, it will operate as if it is overloaded. The motor speed will be low; it will overheat and probably activate the motor overload protector causing short cycling.
