Our take on the Dual Run Capacitor Round CBB65 45/5uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser 2 Pack

This is a round CBB65 dual run capacitor rated 45+5 µF at 370V AC, with a metallized polypropylene element in an aluminum case. It has three top terminals — HERM for the compressor, FAN for the condenser fan and C for common — each with four pins, and it is TUV recognized. It suits air conditioners, heat pumps and other single-phase motors that need a 45 µF compressor section and a 5 µF fan section. The two-pack format matters because these parts fail with age and heat, and a spare saves a second trip. Compared with single-section capacitors it replaces two parts with one can; the trade-off is that both sections must match your motor's ratings.

Pros
  • Dual section covers compressor and fan in one part
  • 370V AC rating with ±5% tolerance
  • TUV recognized
  • Aluminum case resists heat and overvoltage shock
  • Three clearly marked terminals (HERM, FAN, C)
  • Two-pack gives a spare
Cons
  • Must match both capacitance values and voltage exactly
  • Round 55 mm diameter may not fit every mounting bracket
  • No discharge resistor or bleed-down built in
  • Terminal layout differs from some original parts

About the Dual Run Capacitor Round CBB65 45/5uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser 2 Pack

This is a CBB65 dual run capacitor in a round aluminum case, sold as a 2-pack. It is used for starting and running a single-phase motor in a 50Hz/60Hz AC power system. It is rated 45+5uF at 370V AC.

The capacitor has low loss, heat resistance and resistance to overvoltage shock, and it is TUV recognized. The top has three terminals, each with 4 pins. HERM connects to the compressor, FAN to the fan, and C to the common line.

It suits air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC systems, generators, lamps and fans. Replace it if the capacitor on your motor or compressor is burnt out or weak.

Questions and answers

Will this replace a 45/5 µF 370V capacitor?
Yes, if your old part is marked 45+5 µF at 370V AC or lower voltage, with the same three-terminal HERM/FAN/C layout. Match both capacitance numbers and never go below the original voltage rating.
Can I use it on a 440V system?
No. This capacitor is rated 370V AC. A 440V circuit needs a capacitor rated for that voltage.
How do I wire the HERM, FAN and C terminals?
HERM takes the compressor lead, FAN takes the condenser fan lead and C takes the common line. Each terminal has four pins, so the leads push on directly. Power off and discharge the old capacitor before touching it.
What size is the case?
The body is about 4.9 inches tall and 2.2 inches in diameter. Check the space and bracket in your unit before ordering.
Is one capacitor enough for both the compressor and the fan?
Yes. The 45 µF section runs the compressor and the 5 µF section runs the fan, so one can replaces two separate capacitors.
Does it come with mounting hardware?
The pack contains two capacitors. Mounting brackets and screws are not included, so reuse the existing strap or bracket.
