Our take on the Dual Run Capacitor Round CBB65 50/7.5uF 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 50+7.5 uF at 370V AC, with a metallized polypropylene element in an aluminum case. It has three top terminals labeled HERM (compressor), FAN, and C (common), each with four pins, and measures about 5.3 inches tall by 2.2 inches across. It suits single-phase motors in 50/60 Hz systems: air conditioner compressors, condenser fans, heat pumps and similar HVAC gear. The two-pack format means a spare for the next failure; the main trade-off against single capacitors is that both sections must match your motor's ratings, and the 370V rating is below 440V units used on some larger systems.

About the Dual Run Capacitor Round CBB65 50/7.5uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser 2 Pack

This CBB65 dual run capacitor is built for starting and running a single-phase motor in a 50Hz/60Hz AC power system. It combines two capacitances, 50 uF and 7.5 uF, in one round aluminum case. It is TUV recognized.

The capacitor is made of metallized polypropylene. It has low loss, heat resistance, resistance to overvoltage shock and a long service life. The top has three terminals, each with 4 pins: HERM for the compressor, FAN for the fan, and C for the common line.

It suits air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC systems, generators, lamps and fans. Use it to replace a capacitor that is burnt out or weak.

Questions and answers

Will this replace my old dual run capacitor?
Only if the old part reads 50 uF for the compressor and 7.5 uF for the fan at 370V AC or higher. Match the uF values and the voltage rating, then wire HERM, FAN and C to the same terminals as before.
Is 370V enough, or do I need 440V?
370V AC is fine for many residential condenser and heat pump motors. If your old capacitor is marked 440V, buy a 440V replacement instead of stepping down.
How do I wire the three terminals?
HERM goes to the compressor circuit, FAN to the fan motor, and C to the common line. Each terminal has four pins, so leads seat firmly. Discharge the old capacitor and cut power before touching anything.
What size is the case?
About 5.3 inches tall and 2.2 inches in diameter. Check the space in your unit and your mounting bracket before ordering, since no strap is included.
What is in the box?
Two CBB65 capacitors. No mounting hardware, wires or instructions are included.
Can I use it on a refrigerator or generator?
It works on single-phase motors in 50/60 Hz systems, including some refrigerators, fans and generators, as long as the capacitance and voltage match the motor's spec.
