Our take on the Dual Run Capacitor Round CBB65 50/10uF 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 50+10uF 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, C for common), each with four pins, and is built for 50/60Hz single-phase motors in air conditioners, heat pumps and compressors. The 40/85/21 climatic rating covers operation up to 85°C, which matters on hot condenser decks. It is a standard replacement part rather than a premium brand unit, so fit and terminal layout matter more than brand name when choosing between rivals.

Pros
  • Dual section covers compressor and fan in one can
  • 450V AC rating gives headroom over 370V parts
  • Three labeled terminals with four pins each for secure connections
  • Aluminum case and 40/85/21 rating suit hot outdoor units
  • ±5% tolerance is tight for this class of capacitor
Cons
  • No mounting strap or bracket included
  • Round 55mm diameter may not fit every OEM bracket
  • Unbranded part, so quality control varies between units
  • No discharge resistor or bleed-down feature mentioned

About the Dual Run Capacitor Round CBB65 50/10uF 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 a single-phase motor in a 50Hz/60Hz AC power system. It has low loss, heat resistance, resistance to overvoltage shock and a long service life. It replaces a capacitor that is burnt out or weak.

The aluminum case holds a metallized polypropylene element. 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 can be used with air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC systems, generators, illuminating lamps and fans.

Questions and answers

Will this replace a 50/10uF 450V capacitor?
Yes, if your old can is a dual section rated 50+10uF at 450V AC or lower voltage. Match the capacitance and voltage, and check that the round case fits your bracket.
What do the HERM, FAN and C terminals mean?
HERM connects to the compressor, FAN to the condenser fan motor, and C to the common line. Each terminal has four pins for the lead wires.
Can I use it on a 370V circuit?
Yes. A 450V AC rating is a higher voltage class than 370V, so it can replace a 370V part as long as the capacitance values match.
What size is the case?
The body is about 135mm long and 55mm in diameter (5.3 x 2.2 inches). Measure your old capacitor and its mounting space before ordering.
Does it work for heat pumps and refrigeration?
Yes. It is intended for single-phase motors in 50/60Hz systems, including heat pump condensers, air compressors and refrigerators.
What is in the box?
One CBB65 dual run capacitor. No mounting bracket, strap or wiring is included.
