Our take on the Dual Run Capacitor Round CBB65 70/5uF mfd 450V AC 40/85/21 Aluminum Case with Terminal for Air Conditioner Compressor Motor Heat Pump Condenser

This is a round dual run capacitor for single-phase AC motors: 70 µF for the compressor (HERM) and 5 µF for the fan (FAN), rated 450V AC at 50/60 Hz. The metallized polypropylene element sits in a round aluminum case about 4.9 inches long and 2.5 inches across, with three four-pin terminals on top. It is the standard replacement part when an AC compressor or condenser fan motor hums, starts slowly or won't start. Against single-value capacitors it saves a slot and a wiring step, but it must match the original's two capacitance values and its physical size to fit the mounting strap and cover.

Pros
  • Two values in one can: 70 µF compressor and 5 µF fan
  • 450V AC rating gives headroom over 370V parts
  • ±5% tolerance on rated capacitance
  • Labeled HERM, FAN and C terminals simplify wiring
  • Round aluminum case with standard 2.5-inch diameter
Cons
  • Must match both capacitance values and the can size exactly
  • No mounting strap or hardware included
  • Only one capacitor in the box
  • Wrong value or wiring can damage the compressor

About the Dual Run Capacitor Round CBB65 70/5uF 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, resistance to overvoltage shock and a long service life.

The body is metallized polypropylene in an aluminum case. Three terminals on top are marked HERM, FAN and C, with 4 pins per terminal. HERM connects to the compressor, FAN to the fan, and C to the common line.

It is used in air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC equipment, generators, illuminating lamps and fans. It replaces a motor or compressor capacitor that is burnt out or weak.

Questions and answers

Will this replace my old dual run capacitor?
Only if your old part is also 70 µF for the compressor and 5 µF for the fan, rated 450V AC or lower, and the same round 2.5-inch diameter fits your strap and cover. Check the label on the old can before ordering.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor circuit, FAN to the condenser fan motor, and C to the common line. Each terminal has four pins, so several wires can land on one post.
Is 450V AC enough for my unit?
450V AC covers most residential and light commercial single-phase compressors and fan motors that specify 370V or 440V. Do not use it where the original is rated higher.
Does it come with a mounting bracket?
No. The box contains one capacitor only. Reuse the existing strap or bracket from the old capacitor.
How do I know the old capacitor is bad?
Common signs are a compressor or fan that hums without starting, slow starts, or a bulged top. A multimeter capacitance test confirms it before you replace anything.
