This is a round CBB65 dual run capacitor rated 45+10uF at 370V AC, with a metallized polypropylene element in an aluminum case. It has three top terminals — HERM for the compressor, FAN for the fan and C for common — each with four pins, so one part covers both the compressor and condenser fan circuits. It suits AC, heat pump and refrigeration repair where the original capacitor has failed or gone weak. Against single-value capacitors it saves a separate fan cap and wiring, but it is a plain 370V part, not the higher-rated 440V units some techs prefer for headroom.

This CBB65 dual run capacitor is rated 45+10 uF at 370V AC. It is built with metallized polypropylene in a round aluminum case. It is TUV recognized and has low loss, heat resistance and resistance to overvoltage shock.
The top has three terminals 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 is used for starting and running single-phase motors in 50Hz/60Hz AC power systems. Typical uses include air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC equipment, generators, lamps and fans. It can replace a capacitor in a motor or compressor that is burnt out or weak.
