Our take on the Dual Run Capacitor Round CBB65 30/7.5uF 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 for single-phase AC motors: 30 µF for the compressor (HERM) and 7.5 µF for the fan (FAN), with a shared common terminal. It is rated 450V AC, 50/60Hz, ±5% tolerance, in a 125x50mm aluminum case with three four-pin terminals. It suits air conditioners, heat pumps, condensers and other motor start/run duty. Against single-value capacitors it replaces two parts with one can, but it is a generic part: match the microfarad ratings, voltage and terminal layout to the old unit before buying.

Pros
  • Two capacitances in one can: 30 µF compressor plus 7.5 µF fan
  • 450V AC rating gives headroom over 370V parts
  • Metallized polypropylene with low loss and heat resistance
  • Labeled HERM, FAN and C terminals for straightforward wiring
  • Aluminum case with 40/85/21 climatic rating
Cons
  • Generic part: brand and manufacturing quality vary
  • No mounting bracket or hardware included
  • Must match exact µF values and terminal layout or the motor runs wrong
  • Fails like any run capacitor; no diagnostic help in the box

About the Dual Run Capacitor Round CBB65 30/7.5uF 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 capacitor has an aluminum case and metallized polypropylene construction. Three terminals sit on top: HERM for the compressor, FAN for the fan, and C for the common line. Each terminal has 4 pins.

It is used in air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC systems, generators, lamps and fans. It can replace a motor or compressor capacitor that is burnt out or weak.

Questions and answers

Will this replace a 30/7.5 µF 370V capacitor?
Yes, if the ratings and terminal layout match. The 450V AC rating is higher than 370V, which is acceptable; never go lower on voltage. Confirm the old can reads 30+7.5 µF and has HERM, FAN and C terminals.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor circuit (30 µF), FAN to the fan motor (7.5 µF), and C is the common line shared by both. Each terminal has four pins.
What size is it?
The case is about 125mm long and 50mm in diameter (roughly 4.9 x 2 inches). Measure the old capacitor and its mounting space before ordering.
Can I use it on a refrigerator or a plain motor?
Only if that motor needs a 30 µF and 7.5 µF split and is rated for 450V AC at 50/60Hz. For a single-value motor, a single run capacitor is the correct part.
Is it safe to replace myself?
Only with the power off and the old capacitor discharged, since it can hold a charge. If you are not comfortable working on HVAC line voltage, have a technician do it.
