Our take on the Dual Run Capacitor Round CBB65 70/7.5uF 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 air conditioner compressors, heat pumps and condenser fan motors. It packs two capacitances in one can: 70uF for the compressor (HERM) and 7.5uF for the fan (FAN), sharing a common terminal (C). The metallized polypropylene element in an aluminum case is rated 450V AC, 50/60Hz, ±5% tolerance, with a 40/85/21 climatic category. It suits anyone replacing a failed or weak dual capacitor on a single-phase HVAC motor; the main trade-off against single-value capacitors is that both ratings must match the old part exactly, and the 70uF compressor side is a large value that fits only motors specifying it.

Pros
  • Two capacitances in one can: 70uF compressor plus 7.5uF fan
  • 450V AC rating gives headroom on 240V systems
  • ±5% tolerance keeps motor starting close to spec
  • Three labeled terminals (HERM, FAN, C) simplify wiring
  • Aluminum case with 40/85/21 rating for heat resistance
Cons
  • Must match both microfarad values and voltage exactly
  • 70uF is a high compressor value; not a universal replacement
  • Round 63mm diameter may not fit every mounting bracket
  • No discharge resistor or bleed-down feature mentioned
  • Single unit only, so no spare on hand

About the Dual Run Capacitor Round CBB65 70/7.5uF 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 with metallized polypropylene film in a round aluminum case. It has low loss, heat resistance and resistance to overvoltage shock, and it is made for long service life.

It is used for starting and running a single-phase motor in a 50Hz/60Hz AC power system. The top has three terminals: HERM for the compressor, FAN for the fan, and C for the common line. Each terminal has 4 pins.

It fits air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC equipment, generators, illuminating lamps and fans. It can replace 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 a dual capacitor with 70uF on the compressor side and 7.5uF on the fan side, rated 450V AC or lower. Match both microfarad values and the voltage rating; a different value can damage the motor.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor, FAN to the condenser fan motor, and C is the common line shared by both. Each terminal has four pins.
Is 450V AC enough for my system?
Yes for typical 240V residential AC and heat pump systems, since the rating exceeds the running voltage with margin. Never use a capacitor rated below the original's voltage.
What size is the can?
It is round, about 63mm (2.5 inch) in diameter and 150mm (5.9 inch) long. Check your mounting bracket and clearance before ordering.
Does it work on 50Hz and 60Hz power?
Yes, it is rated for both 50Hz and 60Hz single-phase AC systems.
What is in the box?
One CBB65 dual run capacitor. Wiring and mounting hardware are not included.
