Our take on the Dual Run Capacitor Round CBB65 30/3uF 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 30+3 µF at 450V AC, with three top terminals: HERM for the compressor, FAN for the fan, and C for the common line. It uses metallized polypropylene film in a 50 mm diameter, 125 mm long aluminum case, rated for 50/60 Hz and a 40/85/21 climate category. It is a service part for single-phase motors in air conditioners, heat pumps, compressors and similar HVAC equipment. Compared with single-value capacitors, one can replaces two, which saves space and wiring inside the unit.

Pros
  • One can covers both compressor (30 µF) and fan (3 µF) circuits
  • 450V AC rating suits most residential condenser units
  • Three clearly marked terminals (HERM, FAN, C) simplify wiring
  • Metallized polypropylene film gives low loss and good heat resistance
  • Aluminum case with 4-pin terminals per post for secure connections
Cons
  • Must match the original capacitance and voltage exactly; wrong values damage the motor
  • Requires discharging before removal for safety
  • No mounting bracket or hardware included
  • Round 50 mm can may not fit every mounting clamp
  • Not a universal part; some units need different µF splits

About the Dual Run Capacitor Round CBB65 30/3uF 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, anti-overvoltage shock resistance and a long service life.

The body is metallized polypropylene in an aluminum case. 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 equipment, generators, illuminating lamps and fans. Replace the capacitor with a new one if the one in your motor or compressor is burnt out or weak.

Questions and answers

Will this replace my old 30/3 µF capacitor?
Yes, if your old capacitor is a dual run type rated 30 µF for the compressor and 3 µF for the fan at 450V AC or lower. Match the capacitance and voltage on the old label before ordering.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor circuit, FAN to the fan motor, and C to the common line. Each post has four pins for the lead connections.
Is it safe to install myself?
Only if you are comfortable working with line voltage. Shut off power at the breaker and discharge the old capacitor before touching the terminals.
What size is the can?
It is about 50 mm in diameter and 125 mm long, so check the space and clamp in your unit before fitting it.
Does it work on 50 Hz and 60 Hz systems?
Yes, it is rated for both 50 Hz and 60 Hz AC power systems.
