Our take on the Dual Run Capacitor Round CBB65 55/7.5uF mfd 450V AC 40/85/21 Aluminum Case with Terminal for Air Conditioner Compressor Motor Heat Pump Condenser

This is a round CBB65 dual run capacitor with a 55 µF compressor section and a 7.5 µF fan section, rated 450V AC for 50/60 Hz systems. It has three top terminals marked HERM, FAN and C, each with four pins, in a 125 x 63 mm aluminum case. It is a direct replacement part for a failed or weak capacitor in an air conditioner compressor, heat pump condenser or single-phase motor. Buyers should match the microfarad values, voltage rating and case size to the original part before ordering.

Pros
  • Dual section covers compressor and fan in one can
  • 450V AC rating gives headroom over 370V parts
  • Metallized polypropylene film for low loss
  • Clear HERM, FAN and C terminal markings
  • Aluminum case with 40/85/21 climatic rating
Cons
  • Only fits equipment needing this exact 55/7.5 µF split
  • No mounting bracket or hardware included
  • Must be discharged and wired correctly or it fails fast
  • Wrong capacitance can damage the compressor motor

About the Dual Run Capacitor Round CBB65 55/7.5uF mfd 450V AC 40/85/21 Aluminum Case with Terminal for Air Conditioner Compressor Motor Heat Pump Condenser

This CBB65 dual run capacitor is built for starting and running single-phase motors in 50Hz/60Hz AC power systems. It has low loss, heat resistance and resistance to overvoltage shock, with a long service life. It has an aluminum case and metallized polypropylene construction.

Three terminals sit on top: HERM for the compressor, FAN for the fan and C for the common line. Each terminal has 4 pins. It is used in air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC equipment, generators, lamps and fans. It can replace a burnt-out or weak capacitor on a motor or compressor.

Questions and answers

How do I know this capacitor fits my unit?
Check the old capacitor's label for 55+7.5 µF, 450V AC and a 63 mm diameter by 125 mm case. The terminal layout should also match HERM, FAN and C on top.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor, FAN to the fan motor and C to the common line. Each terminal has four pins for the wire leads.
Can I use a 370V capacitor instead of this 450V one?
Only if the original part was rated 370V. A 450V rating is safe where 370V was specified, but never go lower than the original voltage.
Does the capacitance tolerance matter?
Yes. This part is ±5%, which is tight enough for compressor and fan circuits. A capacitor far off its rated value can cause hard starting or motor overheating.
What is in the box?
One CBB65 dual run capacitor. No bracket, screws or wiring instructions are included.
When should a run capacitor be replaced?
When the compressor hums but does not start, the fan runs slowly, or the top of the can looks bulged or burnt. Test with a capacitance meter before swapping.
