Our take on the Dual Run Capacitor Round CBB65 40/10uF 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 rated 40+10uF at 450V AC, with a metallized polypropylene element in an aluminum case. It has three top terminals (HERM, FAN, C) with four pins each, so one part serves both the compressor and the condenser fan on a single-phase AC motor. It suits AC, heat pump and refrigeration repair where the original capacitor is weak or burnt out. Against single-value capacitors it saves a second part and wiring, but it is a generic part with no brand backing, so match the ratings exactly.

Pros
  • Dual 40+10uF section covers compressor and fan in one part
  • 450V AC rating and ±5% tolerance match common OEM specs
  • Three labeled terminals (HERM, FAN, C) simplify wiring
  • Aluminum case with metallized polypropylene element resists heat
  • Fits a 55mm diameter, 125mm long round can
Cons
  • Generic part with no recognized capacitor brand
  • No discharge resistor or mounting strap included
  • Must match the original microfarad rating exactly or the motor runs wrong
  • Single unit only, no spare

About the Dual Run Capacitor Round CBB65 40/10uF 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 capacitor has an aluminum case and metallized polypropylene construction. Three terminals sit on top, labeled 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 systems, generators, illuminating lamps and fans. Replace it with a new one if the capacitor in your motor or compressor is burnt out or weak.

Questions and answers

Will this replace a 40/10uF 440V capacitor?
Yes, if the original is a dual 40+10uF round can. The 450V AC rating meets or exceeds a 440V original, and the 55mm diameter and 125mm length must fit the mounting space.
What do the HERM, FAN and C terminals mean?
HERM feeds the compressor, FAN feeds the condenser fan motor, and C is the common line. Each terminal has four pins for the push-on connectors.
Can I use it on a 50Hz system?
Yes. It is rated for 50/60Hz AC systems, so it works on both North American 60Hz and 50Hz power.
Does it fit both air conditioners and heat pumps?
Yes. It is used in AC compressors, heat pump condensers, refrigerators, motors and similar single-phase equipment, as long as the ratings match.
What is in the box?
One CBB65 dual run capacitor. No mounting bracket, strap or wiring is included.
How do I know my old capacitor is bad?
A weak or burnt-out capacitor shows a bulged top, leaking oil, or a compressor or fan that hums and won't start. Confirm with a capacitance meter before replacing.
