Our take on the Dual Run Capacitor Round CBB65 45/10uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser

This is a round CBB65 dual run capacitor rated 45+10uF at 370V AC, with a metallized polypropylene element in an aluminum case. It has three top terminals — HERM for the compressor, FAN for the fan and C for common — each with four pins, so one part covers both the compressor and condenser fan circuits. It suits AC, heat pump and refrigeration repair where the original capacitor has failed or gone weak. Against single-value capacitors it saves a separate fan cap and wiring, but it is a plain 370V part, not the higher-rated 440V units some techs prefer for headroom.

Pros
  • Two values in one can: 45uF compressor and 10uF fan
  • Tight ±5% tolerance
  • TUV recognized
  • Aluminum case with heat and overvoltage resistance
  • Clear HERM/FAN/C terminal labeling
Cons
  • 370V AC rating, not the 440V some techs prefer
  • Round 55mm case may not fit every mounting bracket
  • Only one capacitor in the box; no mounting hardware
  • Must match the original capacitance exactly or the motor runs wrong

Questions and answers

Will this replace my old 45/10uF capacitor?
Yes, if your original is a dual run cap with the same 45+10uF values and 370V or lower rating. Match the capacitance and voltage on the old label before ordering.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor, FAN to the condenser fan motor and C to the common line. Each terminal has four pins for the wire leads.
Can I use it on a 440V system?
No. This cap is rated 370V AC. Use a 440V-rated capacitor where the original or the nameplate calls for it.
Does it work for heat pumps and refrigeration too?
Yes. It is built for single-phase motors in 50/60Hz systems, including heat pump condensers, refrigerators and compressors.
What size is the case?
About 135mm tall and 55mm in diameter (5.3 x 2.2 inches). Check your mounting space before installing.
What is in the box?
One CBB65 dual run capacitor. No mounting bracket or screws are included.
