Our take on the Dual Run Capacitor Round CBB65 35/7.5uF 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 rated 35+7.5 µF at 450V 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, and it is built for 50/60 Hz single-phase motor start and run duty in air conditioners, heat pumps, compressors and refrigerators. The 40/85/21 climatic rating and ±5% tolerance put it in line with the general-purpose dual run capacitors sold for HVAC repair. It suits a DIYer or technician replacing a weak or burnt-out capacitor with the same 35/7.5 µF, 450V rating; the round 55 mm case and 125 mm body length must fit the existing strap and wiring space.

Pros
  • Dual section covers compressor and fan in one can
  • 450V AC rating gives headroom on 240V systems
  • ±5% tolerance matches typical OEM specs
  • Four pins per terminal for secure lead seating
  • Aluminum case resists heat and corrosion
  • Works on 50 Hz and 60 Hz supplies
Cons
  • Must match the old capacitor's µF ratings exactly
  • Round 55 mm can may not fit every mounting strap
  • No discharge resistor or bleed-down built in
  • Single unit only, no mounting hardware included

About the Dual Run Capacitor Round CBB65 35/7.5uF 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, resistance to overvoltage shock and a long service life.

The metallized polypropylene capacitor sits in a round 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 suits air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC equipment, generators, lamps and fans. It can replace a capacitor in a motor or compressor that is burnt out or weak.

Questions and answers

Will this replace my old 35/7.5 µF capacitor?
Yes, if the old can reads 35 µF for HERM and 7.5 µF for FAN at 370V or 450V. Match both capacitance values and the voltage rating; a higher voltage rating is fine, different µF values are not.
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 shared by both. Wire each lead to the same terminal it came from on the old capacitor.
Does the 450V rating matter on a 240V system?
It gives margin over the roughly 240V the capacitor sees in a residential unit, and it is the common rating for this size. Never substitute a lower voltage rating.
Will it fit my unit?
The case is about 125 mm long and 55 mm across, so check the strap and clearance in your control box. Measure the old can before ordering.
Is it safe to discharge before handling?
Yes. Capacitors hold a charge after power is off; short the terminals with an insulated resistor before touching the leads, and cut power at the breaker first.
What is in the box?
One CBB65 dual run capacitor. Mounting straps and wiring are not included.
